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

Where 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.


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


Display gcc version:

Type the following command
$ gcc -v
Sample outputs:

 Reading specs from /usr/lib/gcc/x86_64-redhat-linux/3.4.6/specs
Configured with: ../configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --enable-shared --enable-threads=posix --disable-checking --with-system-zlib --enable-__cxa_atexit --disable-libunwind-exceptions --enable-java-awt=gtk --host=x86_64-redhat-linux
Thread model: posix
gcc version 3.4.6 20060404 (Red Hat 3.4.6-3)

Installing GNU compiler collection

You need to use the up2date or yum or apt-get command to install gcc and required libs.

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:

# up2date gcc

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

# yum install gcc

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

$ sudo apt-get install gcc
# apt-get install gcc

    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??

    • Brian November 17, 2012, 2:05 pm

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

      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.

  • vidhu July 21, 2012, 2:03 pm

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

    • Halluka August 2, 2013, 4:22 pm

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

    How to install gcc ?
    thx a lot

  • cameron August 29, 2012, 4:17 am

    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.

    • Brian November 17, 2012, 2:08 pm

      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 am using Kubuntu
    When I am giving command “# apt-get install gcc”
    It will give error like this,
    Reading package lists… Done
    Building dependency tree
    Reading state information… Done
    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 ?
