Find gcc on linux

Where is My Linux GNU C or GCC Compilers Are Installed?

W here is my GNU C compiler? Where does the GNU C (gcc) compiler reside in the RHEL / Fedora / Debian / Ubuntu / CentOS Linux installation? How do I install GNU c/c++ compiler in Linux operating systems?

The GNU Compiler Collection (GCC) is a compiler system. It was created by the GNU Project supporting various programming languages such as C (gcc), C++ (g++), Objective-C, Objective-C++, Fortran (gfortran), Java (gcj), Ada (GNAT), and Go (gccgo).

You need to use the which command to locate c compiler binary called gcc. Usually, it is installed in /usr/bin directory.

Syntax

Open a terminal and then type the following which command to see Linux C Compiler location:
$ which g++
$ which cc
$ which gcc
Sample outputs:

Another option is to use the type command as follows:
$ type -a gcc
$ type -a cc
$ type -a g++
OR use the command command as follows:
$ command -V gcc
$ command -V cc
$ command -V g++
Sample outputs:

Installing GNU compiler collection

You need to use the up2date command or yum command or apt-get command/apt command to install GNI C/C++ (gcc) and required libs as per your Linux distro.

Note: You must login as root using su — or sudo -s command and then use command as per your distro.

If you are using Red Hat Enterprise Linux version 4.0 or older , type the command:

If you are using CentOS/Fedora Linux or RHEL version 5.0 or above , type the command:

# yum group install «Development Tools»

If you are using Debian /Ubuntu Linux , type the command:

$ sudo apt-get install build-essential
OR
# apt-get install build-essential

Writing a sample test code

You can create a sample c code as follows:
$ vi foo.c
Append the following code:

Compile it as follows:
$ cc foo.c -o foo
$ ls -l foo
$ ./foo
Sample outputs:

please help me how to solve this problem.

hi, when i type the command ‘ yum install gcc’ , i got a reply as ‘you need to be a root to perform this command…”
what does it mean??

It means you need to be superuser by using the command:
su

Then it will prompt for a password, then you will be able to install using the same command.

As an alternative log in as the root user.

when i giv the command “yum install gcc”, it says i need to be a root to perform this command… wht shld i do??

It means you need to google “you need to be a root to perform this command…”.

I have centos installed,
ls -l glibc-*

How to install gcc ?
thx a lot

I had the need to be in root to perform this command error so I thought Id share the solution I found (im using centOS). I used the command – sudo yum install gcc-c++

BUT that is for c++ compiling so for C use sudo yum install gcc

It seems that you need to put sudo in front of the command to use root 0.o maybe.

Sudo will raise the priv level of the currently logged in user to execute the task listed after it (you can also find out more with: man sudo), it is like right clicking in Windows and selecting to run as administrator.

I have several error to comiple SPEC2006. can you help
specmake: icc: Command not found
Error with make ‘specmake build’
specmake: *** [spec.o] Error 127
Command returned exit code 2
Error with make!

how i get my c++ compiler in linux please give me steps n how i will compile my program

hey what should we give for password? it’s not taking any characters

just enter your password(log in one)
it will not show any thing on display but type your password & press enter .
installation will start

i want to clean gcc4.3 in ubuntu and install gcc2.96 .
i dont know how do .
please help me .
thanks

Please let me know how can I install gcc on my RHEL6

i got error msg -can not access archive while insataling gcc
what i have to do

Hi,
I found below error. Please help.

Hi,
I am using Kubuntu
When I am giving command “# apt-get install gcc”
It will give error like this,

Package gcc is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package ‘gcc’ has no installation candidate

Can you help me ?

Hi when I type in yum it says command not found. Help.

I got exactly what i was looking for in this tutorial, Thanks!

Hello,
Thank you for the useful information. I have an issue when I use the “type” command, it gives the following output:

gcc is /usr/bin/gcc
gcc is /bin/gcc

The same case is repeated when I run type cc and g++. Can you please help me to resolve this because Im having compiling issues.

Installing GCC

This page is intended to offer guidance to avoid some common problems when installing GCC, the official installation docs are in the Installing GCC section of the main GCC documentation. N.B. those installation docs refer to the development trunk, the installation instructions for released versions are included in the release sources.

For most people the easiest way to install GCC is to install a package made for your operating system. The GCC project does not provide pre-built binaries of GCC, only source code, but all GNU/Linux distributions include packages for GCC. The BSD-based systems include GCC in their ports collections. For other operating systems the Installing GCC: Binaries page lists some third-party sources of GCC binaries.

If you cannot find suitable binaries for your system, or you need a newer version than is available, you will need to build GCC from source in order to install it.

Building GCC

Many people rush into trying to build GCC without reading the installation docs properly and make one or more of these common mistakes:

do not run ./configure from within the source directory, this is not supported. You need to run configure from outside the source directory, in a separate directory created for the build (this is a FAQ)

if GCC links dynamically to the GMP, MPFR or MPC support libraries then the relevant shared libraries must be in the dynamic linker’s path, both when building gcc and when using the installed compiler (this is also a FAQ)

Support libraries

See Installing GCC: Prequisites for the software required to build GCC. If you do not have the GMP, MPFR and MPC support libraries already installed as part of your operating system then there are two simple ways to proceed, and one difficult, error-prone way. For some reason most people choose the difficult way. The easy ways are:

If it provides sufficiently recent versions, use your OS package management system to install the support libraries in standard system locations. For Debian-based systems, including Ubuntu, you should install the packages libgmp-dev, libmpfr-dev and libmpc-dev. For RPM-based systems, including Fedora and SUSE, you should install gmp-devel, mpfr-devel and libmpc-devel (or mpc-devel on SUSE) packages. The packages will install the libraries and headers in standard system directories so they can be found automatically when building GCC.

Alternatively, after extracting the GCC source archive, simply run the ./contrib/download_prerequisites script in the GCC source directory. That will download the support libraries and create symlinks, causing them to be built automatically as part of the GCC build process. Set GRAPHITE_LOOP_OPT=no in the script if you want to build GCC without ISL, which is only needed for the optional Graphite loop optimizations.

The difficult way, which is not recommended, is to download the sources for GMP, MPFR and MPC, then configure and install each of them in non-standard locations, then configure GCC with —with-gmp=/some/silly/path/gmp —with-mpfr=/some/silly/path/mpfr —with-mpc=/some/silly/path/mpc, then be forced to set LD_LIBRARY_PATH=/some/silly/path/gmp:/some/silly/path/mpfr:/some/silly/path/mpc/lib in your environment forever. This is silly and causes major problems for anyone who doesn’t understand how dynamic linkers find libraries at runtime. Do not do this. If building GCC fails when using any of the —with-gmp or —with-mpfr or —with-mpc options then you probably shouldn’t be using them.

Configuration

See Installing GCC: Configuration for the full documentation. A major benefit of running srcdir /configure from outside the source directory (instead of running ./configure) is that the source directory will not be modified in any way, so if your build fails or you want to re-configure and build again, you simply delete everything in the objdir and start again.

For example, configuring and building GCC 4.6.2 (with support for C, C++, Fortran and Go) should be as simple as:

The make step takes a long time. If your computer has multiple processors or cores you can speed it up by building in parallel using make -j 2 (or a higher number for more parallelism).

If your build fails and your configure command has lots of complicated options you should try removing options and keep it simple. Do not add lots of configure options you don’t understand, they might be the reason your build fails.
