How to install the C++ Boost Libraries on Windows

By Andres Jaimes

September 27, 2012

Boost is a set of high-quality libraries that speed up C++ development. They are included in most linux distributions and some of them are already part of the C++ Standard Library. In the Windows environment, you have to install them in order to take advantage of them.

If you are using Microsoft Visual Studio, you can avoid the following steps by downloading a binary version from http://www.boostpro.com/download/ and skip to the Testing section in this document.

Before we start, you may want to read my previous article on installing a C++ compiler on Windows.

Installation

Download and unzip the boost source code from http://www.boost.org/ . I will unzip it to C:optc-libs, but you can use the one you prefer. After you unzip, open a command line and go to your selected folder:

Start bootstrap.bat and specify your toolset. Toolsets supported by this script are: borland, como, gcc, gcc-nocygwin, intel-win32, metrowerks, mingw, msvc, vc7, vc8, vc9, vc10, vc11. In my case I will use the mingw toolset:

All required files for compilation should be ready. Now you have to define a installation directory and specify a toolset. Toolsets here are a little bit different from the ones we used before:

• acc: Hewlett Packard, Only very recent versions are known to work well with Boost
• borland: borland
• como: Comeau Computing, Using this toolset may require configuring another toolset to act as its backend
• darwin: Apple, Apple’s version of the GCC toolchain with support for Darwin and MacOS X features such as frameworks.
• gcc: The Gnu Project, including Cygwin and MinGW
• hp_cxx: Hewlett Packard, Targeted at the Tru64 operating system.
• intel: Intel****
• msvc: Microsoft
• sun: Sun, Only very recent versions are known to work well with Boost.
• vacpp: IBM, The VisualAge C++ compiler.

Since I’m using MinGW I will use gcc.

At this time you can go get a cup of coffee. Or maybe two.

When compilation ends, go to your selected installation path (watch out!, this is not the folder where you originally unzipped the source code). You will find two folders: include and lib. Both folders should contain files. That means you are done and ready for the testing phase.

If any of the afore mentioned folders is empty then we have problems. Common problems arise due to selecting the wrong toolset for compiling, so if your lib folder is empty try choosing a different toolset. If error persist, take a look at the compilation output. Errors must be shown there, specially at the last lines of the output.

Testing

From your IDE create a file named main.cpp and copy the following text onto it:

It’s time to compile (and link)

In order to let your compiler know where to look for the headers and libraries, you have to follow the next steps. You can usually accomplish them by right clicking on your project and selecting Properties or Options.

Add the following path to your includes list:

Add the following path to your additional library directories list

Important: if you are using Netbeans, you should only type /installation/path/lib (you have to omit the C:). For a very strange reason, Netbeans adds a forward slash at the beggining of the parameter /L used to compile (only when it begins with C:) resulting in an unknown path. This might be fixed in later versions.

If you are using a gnu compiler (that is Cygwin or MinGW), you must also add the specific library to the linker. If you are using Microsoft Visual Studio you can skip this step because it includes the so called auto-linking support. But, in my case, I have to add the following library to my libraries list so the linker performs without complaints:

This file name is composed by:

• The standard lib prefix. DLL’s do not use it.
• The library name boost_regex.
• The toolset used to compile it, in my case mgw47, that is MinGW version 4.7.
• The threading tag mt, which indicates if the library accepts multithreading.
• The ABI tag, that can be: d for debugging, s for static linkage or g, y, p which are not covered in this text.
• The version tag.
• The extension, which can be .lib or .a.

You are ready. Build the program.

Time to execute it

The program you just compiled (and linked) can parse a text file looking for a line starting with the text “Subject:” in it. So to test it, copy and paste the following text into an empty text file and name it test.txt (save it in the folder where your .exe file resides):

Now, from a command prompt type:

If everything goes right you should see the following text:

Conclusion

At this point, boost should be ready on your Windows computer. I suggest you read about this tremendous library since it can help you make your life a lot easier.

C++ — Qt Framework — Using QOpenGLWidget to display a window for moving shapes with keyboard and mouse

In the past tutorials about Qt and OpenGL we saw how to deal with some basic tasks.

Let’s see this time something a bit more advanced with the QOpenGLWidget class in order to display a scene from a window with a shape.

C++ — Qt Framework — Using OpenGL texture with index array

Playing with colors can be fun but what about textures?

What about something really realistic?

In this OpenGL tutorial for Qt we are going to apply a texture on our dear triangles.

C++ — Qt Framework — Using 1 OpenGL VAO and 2 VBOs with only 1 array for both position and color of each vertex

As we saw, in the last tutorial about using a VAO and VBO to handle 2 different objects on the scene with OpenGL, it’s possible to have 2 arrays of vertex: one to manage the position and one to deal with the color.

C++ — Qt Framework — Using OpenGL VAO and VBO to handle 2 different objects on the scene

VAO (Vertex Array Object) and VBO (Vertex Buffer Object) were introduced to help programmers since OpenGL 3.0.

So it’s not a recent features but if you just started learning OpenGL it could be very complex to understand.

With Android we haven’t a classic ComboBox like in other frameworks but we have instead a Spinner.

Actually it’s exactly the same and only the name differs.

Python 3 — PySide2 — Setting up and using Qt Designer

PySide2 is a Python API for the Qt framework.

This API is made with Shiboken2, the Python binding generator.

It means that you can write your code in Python and use the Qt framework as you’d do with C++.

C++ — Boost — Converting std::vector to Boost.Python Numpy ndarray

You have a C++ std::vector and you want to convert it to a Boost.Python Numpy ndarray.

But, once the ndarray got, you want to get back to the C++ array.

Let’s see that in this Boost.Python tutorial.

C++ — Boost — Using Boost.Python Numpy from_data()

If you are using Python then NumPy is quite interesting for manipulating arrays.

But how do we do that with C++ and Boost.Python NumPy extension?

If you are a scientist and interested in Python, you certainly already know the NumPy package.

In this tutorial I’ll propose to explain how to install it on Windows in order to be used with the Boost.Python library.

We’ll also make an Hello world example.

Installing boost on Windows using MinGW-w64 (gcc 64-bit)

Boost is easy when you are using headers or pre-compiled binaries for visual studio, but it can be a pain to compile from source on windows, especially when you want the 64-bit version of MinGW to use gcc/g++. This installation process should be thorough enough to simply copy and paste commands, but robust enough to install everything you need.

Note: if you need to install any of the libraries that need dependencies, see this great answer from stack overflow

Get files needed for install

Get the MinGW installer mingw-w64-install.exe from Sourceforge
Get the boost_1_68_0.zip source from Sourceforge
Note: This should work perfectly with other versions of boost as well
Copy these to a new folder
C:\install
It should now contain the following two files

Run the installer

Run mingw-w64-install.exe
Click next
Change the Architecture from i868 to x86_64

Click next and keep the default install location
Click next to start the install
Click Finish to exit the installer

After the install, add a hard link (junction) to the folder

Open a command prompt AS ADMIN

• windows key -> type «cmd»
• right click «command prompt»
• Run as administrator
  Enter the following command to create a link to MinGW folder in C:\
  mklink /J C:\MinGW «C:\Program Files\mingw-w64\x86_64-8.1.0-posix-seh-rt_v6-rev0\mingw64»

Add MinGW to the system PATH

Add this to the session and system PATH environment variable
set PATH=%PATH%;C:\MinGW\bin
setx /M PATH «%PATH%»
Check to ensure proper install
g++ —version should return the following info

Navigate to install

unzip to «install/boost_1_68_0»

powershell -command «Expand-Archive C:\install\boost_1_68_0.zip C:\install»
This takes about 15 minutes
cd C:\install\boost_1_68_0

Make directories for building and install

mkdir C:\boost-build
mkdir C:\install\boost_1_68_0\boost-build
mkdir C:\boost

cd C:\install\boost_1_68_0\tools\build
prepare b2
bootstrap.bat gcc
Build boost.build with b2
b2 —prefix=»C:\boost-build» install
Add C:\boost-build\bin to your session PATH variable
set PATH=%PATH%;C:\boost-build\bin

navigate back up to the boost unzipped root directory
cd C:\install\boost_1_68_0
Build boost with b2
b2 —build-dir=»C:\install\boost_1_68_0\build» —build-type=complete —prefix=»C:\boost» toolset=gcc install
This is going to take awhile, so try to run this command right before beginning the director’s cut of Lord of the Ring Return of the King.
When this is done you should see the following output

You can now delete «C:\install» and «C:\boost-build»

Boost C++ Libraries

. one of the most highly regarded and expertly designed C++ library projects in the world. — Herb Sutter and Andrei Alexandrescu, C++ Coding Standards

Getting Started on Windows

A note to Cygwin and MinGW users

If you plan to use your tools from the Windows command prompt, you’re in the right place. If you plan to build from the Cygwin bash shell, you’re actually running on a POSIX platform and should follow the instructions for getting started on Unix variants. Other command shells, such as MinGW’s MSYS, are not supported—they may or may not work.

1 Get Boost

The most reliable way to get a copy of Boost is to download boost_1_55_0 .7z or boost_1_55_0 .zip and unpack it to install a complete Boost distribution. 1

2 The Boost Distribution

This is a sketch of the resulting directory structure:

The organization of Boost library headers isn’t entirely uniform, but most libraries follow a few patterns:

Some older libraries and most very small libraries place all public headers directly into boost \.

Most libraries’ public headers live in a subdirectory of boost \, named after the library. For example, you’ll find the Python library’s def.hpp header in

Some libraries have an “aggregate header” in boost \ that #includes all of the library’s other headers. For example, Boost.Python’s aggregate header is

Most libraries place private headers in a subdirectory called detail \, or aux_ \. Don’t expect to find anything you can use in these directories.

It’s important to note the following:

The path to the boost root directory (often C:\Program Files\boost\ boost_1_55_0) is sometimes referred to as $BOOST_ROOT in documentation and mailing lists .

To compile anything in Boost, you need a directory containing the boost \ subdirectory in your #include path. Specific steps for setting up #include paths in Microsoft Visual Studio follow later in this document; if you use another IDE, please consult your product’s documentation for instructions.

Since all of Boost’s header files have the .hpp extension, and live in the boost \ subdirectory of the boost root, your Boost #include directives will look like:

depending on your preference regarding the use of angle bracket includes. Even Windows users can (and, for portability reasons, probably should) use forward slashes in #include directives; your compiler doesn’t care.

Don’t be distracted by the doc \ subdirectory; it only contains a subset of the Boost documentation. Start with libs \ index.html if you’re looking for the whole enchilada.

3 Header-Only Libraries

The first thing many people want to know is, “how do I build Boost?” The good news is that often, there’s nothing to build.

Nothing to Build?

Most Boost libraries are header-only: they consist entirely of header files containing templates and inline functions, and require no separately-compiled library binaries or special treatment when linking.

The only Boost libraries that must be built separately are:

A few libraries have optional separately-compiled binaries:

• Boost.DateTime has a binary component that is only needed if you’re using its to_string/ from_string or serialization features, or if you’re targeting Visual C++ 6.x or Borland.
• Boost.Graph also has a binary component that is only needed if you intend to parse GraphViz files.
• Boost.Math has binary components for the TR1 and C99 cmath functions.
• Boost.Random has a binary component which is only needed if you’re using random_device.
• Boost.Test can be used in “header-only” or “separately compiled” mode, although separate compilation is recommended for serious use.
• Boost.Exception provides non-intrusive implementation of exception_ptr for 32-bit _MSC_VER==1310 and _MSC_VER==1400 which requires a separately-compiled binary. This is enabled by #define BOOST_ENABLE_NON_INTRUSIVE_EXCEPTION_PTR.

4 Build a Simple Program Using Boost

To keep things simple, let’s start by using a header-only library. The following program reads a sequence of integers from standard input, uses Boost.Lambda to multiply each number by three, and writes them to standard output:

Copy the text of this program into a file called example.cpp.

To build the examples in this guide, you can use an Integrated Development Environment (IDE) like Visual Studio, or you can issue commands from the command prompt. Since every IDE and compiler has different options and Microsoft’s are by far the dominant compilers on Windows, we only give specific directions here for Visual Studio 2005 and .NET 2003 IDEs and their respective command prompt compilers (using the command prompt is a bit simpler). If you are using another compiler or IDE, it should be relatively easy to adapt these instructions to your environment.

Command Prompt Basics

In Windows, a command-line tool is invoked by typing its name, optionally followed by arguments, into a Command Prompt window and pressing the Return (or Enter) key.

To open a generic Command Prompt, click the Start menu button, click Run, type “cmd”, and then click OK.

All commands are executed within the context of a current directory in the filesystem. To set the current directory, type:

followed by Return. For example,

Long commands can be continued across several lines by typing a caret ( ^) at the end of all but the last line. Some examples on this page use that technique to save horizontal space.

4.1 Build From the Visual Studio IDE

From Visual Studio’s File menu, select New > Project…

In the left-hand pane of the resulting New Project dialog, select Visual C++ > Win32.

In the right-hand pane, select Win32 Console Application (VS8.0) or Win32 Console Project (VS7.1).

In the name field, enter “example”

Right-click example in the Solution Explorer pane and select Properties from the resulting pop-up menu

In Configuration Properties > C/C++ > General > Additional Include Directories, enter the path to the Boost root directory, for example

In Configuration Properties > C/C++ > Precompiled Headers, change Use Precompiled Header (/Yu) to Not Using Precompiled Headers. 2

Replace the contents of the example.cpp generated by the IDE with the example code above.

From the Build menu, select Build Solution.

To test your application, hit the F5 key and type the following into the resulting window, followed by the Return key:

Then hold down the control key and press «Z», followed by the Return key.

4.2 Or, Build From the Command Prompt

From your computer’s Start menu, if you are a Visual Studio 2005 user, select

All Programs > Microsoft Visual Studio 2005 > Visual Studio Tools > Visual Studio 2005 Command Prompt

or, if you’re a Visual Studio .NET 2003 user, select

All Programs > Microsoft Visual Studio .NET 2003 > Visual Studio .NET Tools > Visual Studio .NET 2003 Command Prompt

to bring up a special command prompt window set up for the Visual Studio compiler. In that window, set the current directory to a suitable location for creating some temporary files and type the following command followed by the Return key:

To test the result, type:

4.3 Errors and Warnings

Don’t be alarmed if you see compiler warnings originating in Boost headers. We try to eliminate them, but doing so isn’t always practical. 4 Errors are another matter. If you’re seeing compilation errors at this point in the tutorial, check to be sure you’ve copied the example program correctly and that you’ve correctly identified the Boost root directory.

5 Prepare to Use a Boost Library Binary

If you want to use any of the separately-compiled Boost libraries, you’ll need to acquire library binaries.

5.1 Simplified Build From Source

If you wish to build from source with Visual C++, you can use a simple build procedure described in this section. Open the command prompt and change your current directory to the Boost root directory. Then, type the following commands:

The first command prepares the Boost.Build system for use. The second command invokes Boost.Build to build the separately-compiled Boost libraries. Please consult the Boost.Build documentation for a list of allowed options.

5.2 Or, Build Binaries From Source

If you’re using an earlier version of Visual C++, or a compiler from another vendor, you’ll need to use Boost.Build to create your own binaries.

There is also an experimental CMake build for boost, supported and distributed separately. See the Boost.CMake wiki page for more information.

5.2.1 Install Boost.Build

Boost.Build is a text-based system for developing, testing, and installing software. First, you’ll need to build and install it. To do this:

1. Go to the directory tools \ build \ v2 \.
2. Run bootstrap.bat
3. Run b2 install —prefix=PREFIX where PREFIX is the directory where you want Boost.Build to be installed
4. Add PREFIX \ bin to your PATH environment variable.

5.2.2 Identify Your Toolset

First, find the toolset corresponding to your compiler in the following table (an up-to-date list is always available in the Boost.Build documentation).

If you previously chose a toolset for the purposes of building b2, you should assume it won’t work and instead choose newly from the table below.

Toolset Name	Vendor	Notes
acc	Hewlett Packard	Only very recent versions are known to work well with Boost
borland	Borland
como	Comeau Computing	Using this toolset may require configuring another toolset to act as its backend
darwin	Apple Computer	Apple’s version of the GCC toolchain with support for Darwin and MacOS X features such as frameworks.
gcc	The Gnu Project	Includes support for Cygwin and MinGW compilers.
hp_cxx	Hewlett Packard	Targeted at the Tru64 operating system.
intel	Intel
msvc	Microsoft
sun	Sun	Only very recent versions are known to work well with Boost.
vacpp	IBM	The VisualAge C++ compiler.

If you have multiple versions of a particular compiler installed, you can append the version number to the toolset name, preceded by a hyphen, e.g. intel-9.0 or borland-5.4.3 . On Windows, append a version number even if you only have one version installed (unless you are using the msvc or gcc toolsets, which have special version detection code) or auto-linking will fail.

5.2.3 Select a Build Directory

Boost.Build will place all intermediate files it generates while building into the build directory. If your Boost root directory is writable, this step isn’t strictly necessary: by default Boost.Build will create a bin.v2/ subdirectory for that purpose in your current working directory.

5.2.4 Invoke b2

Change your current directory to the Boost root directory and invoke b2 as follows:

For a complete description of these and other invocation options, please see the Boost.Build documentation.

For example, your session might look like this: 3

Be sure to read this note about the appearance of ^, More? and quotation marks ( «) in that line.

The option “—build-type=complete” causes Boost.Build to build all supported variants of the libraries. For instructions on how to build only specific variants, please ask on the Boost.Build mailing list.

Building the special stage target places Boost library binaries in the stage \ lib \ subdirectory of the Boost tree. To use a different directory pass the —stagedir= directory option to b2.

b2 is case-sensitive; it is important that all the parts shown in bold type above be entirely lower-case.

For a description of other options you can pass when invoking b2, type:

In particular, to limit the amount of time spent building, you may be interested in:

• reviewing the list of library names with —show-libraries
• limiting which libraries get built with the —with-library-name or —without-library-name options
• choosing a specific build variant by adding release or debug to the command line.

Boost.Build can produce a great deal of output, which can make it easy to miss problems. If you want to make sure everything is went well, you might redirect the output into a file by appending “ >build.log 2>&1 ” to your command line.

5.3 Expected Build Output

During the process of building Boost libraries, you can expect to see some messages printed on the console. These may include

Notices about Boost library configuration—for example, the Regex library outputs a message about ICU when built without Unicode support, and the Python library may be skipped without error (but with a notice) if you don’t have Python installed.

Messages from the build tool that report the number of targets that were built or skipped. Don’t be surprised if those numbers don’t make any sense to you; there are many targets per library.

Build action messages describing what the tool is doing, which look something like:

5.4 In Case of Build Errors

The only error messages you see when building Boost—if any—should be related to the IOStreams library’s support of zip and bzip2 formats as described here. Install the relevant development packages for libz and libbz2 if you need those features. Other errors when building Boost libraries are cause for concern.

If it seems like the build system can’t find your compiler and/or linker, consider setting up a user-config.jam file as described here. If that isn’t your problem or the user-config.jam file doesn’t work for you, please address questions about configuring Boost for your compiler to the Boost.Build mailing list.

6 Link Your Program to a Boost Library

To demonstrate linking with a Boost binary library, we’ll use the following simple program that extracts the subject lines from emails. It uses the Boost.Regex library, which has a separately-compiled binary component.

There are two main challenges associated with linking:

1. Tool configuration, e.g. choosing command-line options or IDE build settings.
2. Identifying the library binary, among all the build variants, whose compile configuration is compatible with the rest of your project.

Most Windows compilers and linkers have so-called “auto-linking support,” which eliminates the second challenge. Special code in Boost header files detects your compiler options and uses that information to encode the name of the correct library into your object files; the linker selects the library with that name from the directories you’ve told it to search.

The GCC toolchains (Cygwin and MinGW) are notable exceptions; GCC users should refer to the linking instructions for Unix variant OSes for the appropriate command-line options to use.

6.1 Link From Within the Visual Studio IDE

Starting with the header-only example project we created earlier:

1. Right-click example in the Solution Explorer pane and select Properties from the resulting pop-up menu
2. In Configuration Properties >Linker >Additional Library Directories, enter the path to the Boost binaries, e.g. C:\Program Files\boost\ boost_1_55_0 \lib\.
3. From the Build menu, select Build Solution.

6.2 Or, Link From the Command Prompt

For example, we can compile and link the above program from the Visual C++ command-line by simply adding the bold text below to the command line we used earlier, assuming your Boost binaries are in C:\Program Files\boost\ boost_1_55_0 \lib:

6.3 Library Naming

If, like Visual C++, your compiler supports auto-linking, you can probably skip to the next step.

In order to choose the right binary for your build configuration you need to know how Boost binaries are named. Each library filename is composed of a common sequence of elements that describe how it was built. For example, libboost_regex-vc71-mt-d-1_34.lib can be broken down into the following elements:

lib Prefix: except on Microsoft Windows, every Boost library name begins with this string. On Windows, only ordinary static libraries use the lib prefix; import libraries and DLLs do not. 5 boost_regex Library name: all boost library filenames begin with boost_. -vc71 Toolset tag: identifies the toolset and version used to build the binary. -mt Threading tag: indicates that the library was built with multithreading support enabled. Libraries built without multithreading support can be identified by the absence of -mt . -d

ABI tag: encodes details that affect the library’s interoperability with other compiled code. For each such feature, a single letter is added to the tag:

Key	Use this library when:	Boost.Build option
s	linking statically to the C++ standard library and compiler runtime support libraries.	runtime-link=static
g	using debug versions of the standard and runtime support libraries.	runtime-debugging=on
y	using a special debug build of Python.	python-debugging=on
d	building a debug version of your code. 6	variant=debug
p	using the STLPort standard library rather than the default one supplied with your compiler.	stdlib=stlport

For example, if you build a debug version of your code for use with debug versions of the static runtime library and the STLPort standard library in “native iostreams” mode, the tag would be: -sgdpn . If none of the above apply, the ABI tag is ommitted.

-1_34 Version tag: the full Boost release number, with periods replaced by underscores. For example, version 1.31.1 would be tagged as «-1_31_1». .lib Extension: determined according to the operating system’s usual convention. On most unix-style platforms the extensions are .a and .so for static libraries (archives) and shared libraries, respectively. On Windows, .dll indicates a shared library and .lib indicates a static or import library. Where supported by toolsets on unix variants, a full version extension is added (e.g. «.so.1.34») and a symbolic link to the library file, named without the trailing version number, will also be created.

6.4 Test Your Program

To test our subject extraction, we’ll filter the following text file. Copy it out of your browser and save it as jayne.txt:

Now, in a command prompt window, type:

The program should respond with the email subject, “Will Success Spoil Rock Hunter?”

7 Conclusion and Further Resources

This concludes your introduction to Boost and to integrating it with your programs. As you start using Boost in earnest, there are surely a few additional points you’ll wish we had covered. One day we may have a “Book 2 in the Getting Started series” that addresses them. Until then, we suggest you pursue the following resources. If you can’t find what you need, or there’s anything we can do to make this document clearer, please post it to the Boost Users’ mailing list.

—the Boost Developers

[1]	We recommend downloading boost_1_55_0 .7z and using 7-Zip to decompress it. We no longer recommend .zip files for Boost because they are twice as large as the equivalent .7z files. We don’t recommend using Windows’ built-in decompression as it can be painfully slow for large archives.

[2]	There’s no problem using Boost with precompiled headers; these instructions merely avoid precompiled headers because it would require Visual Studio-specific changes to the source code used in the examples.

[3]

In this example, the caret character ^ is a way of continuing the command on multiple lines, and must be the final character used on the line to be continued (i.e. do not follow it with spaces). The command prompt responds with More? to prompt for more input. Feel free to omit the carets and subsequent newlines; we used them so the example would fit on a page of reasonable width. The command prompt treats each bit of whitespace in the command as an argument separator. That means quotation marks ( «) are required to keep text together whenever a single command-line argument contains spaces, as in Also, for example, you can’t add spaces around the = sign as in Оцените статью Вам также может понравиться Windows или Linux: Что лучше выбрать?
