How to Check What Compilers Are Installed on CentOS/RHEL/Ubuntu Linux

osetc

This post will guide you how to check what compilers are install on your CentOS/RHEL/Ubuntu/Debian Linux system. How do I check if GNU GCC Compiler is installed on Linux. How do I list all available compilers that can be installed in Linux.

Check What Compilers Are Installed

Assuming that you have installed core development tools in your Linux system, and you want to check what compilers are installed, how to achieve the results in different Linux distribution system.

For Ubuntu/Debian Linux:

If you are using the Ubuntu/Debian Linux, you can use the dpkg command to check what compilers have been installed in your system. Issue the following command:

$ dpkg --list | grep compiler

Outputs:

devops@devops-osetc:~$ dpkg --list | grep compiler
ii g++ 4:5.3.1-1ubuntu1 amd64 GNU C++ compiler
ii g++-5 5.4.0-6ubuntu1~16.04.4 amd64 GNU C++ compiler
ii gcc 4:5.3.1-1ubuntu1 amd64 GNU C compiler
ii gcc-5 5.4.0-6ubuntu1~16.04.4 amd64 GNU C compiler
ii hardening-includes 2.7ubuntu2 all Makefile for enabling compiler flags for security hardening
ii libllvm3.8:amd64 1:3.8-2ubuntu4 amd64 Modular compiler and toolchain technologies, runtime library
ii libxkbcommon0:amd64 0.5.0-1ubuntu2 amd64 library interface to the XKB compiler - shared library

For the above outputs, you can know that the GNU GCC compiler has been installed. and you can use it to compile C or C++ programs on your Linux system.

For CentOS/RHEL Linux:

If you are using the Centos/RHEL Linux, and you can use the “yum install installed” command to check what compilers are installed. Issue the following command:

# yum list installed | grep gcc

or

# yum list installed | grep java

or

# yum list installed | grep automake

Outputs:

[root@osetc_test working]# yum list installed | grep -i --color compiler

Check C/C++ Compiler is Installed

If you want only check if C/C++ compiler is installed on Linux, you can run the following command:

$ type -a gcc

or

$ which gcc

Outputs:

[root@osetc_test working]# type -a gcc
gcc is /usr/bin/gcc
[root@osetc_test working]# which gcc
/usr/bin/gcc

Check C/C++ Compilers Version

To check the version of GNU GCC C/C++ Compiler on your Linux system, you can issue the following command:

$ gcc --version

outpus:

[root@osetc_test working]# gcc --version
gcc (GCC) 4.4.7 20120313 (Red Hat 4.4.7-23)

Check which Fortran Compiler is installed

To check the version of installed fortran compiler on your Linux system, type the following command:

$ gfortran -v

outputs;

[root@osetc_test working]# gfortran -v

Check All Available Compilers Can be Installed

If you want to check the list of available compilers can be installed in your system, you can execute the following command:

Install Compiler in Linux

To install compilers on your Linux system, you can use the yum command to install the specific compiler, such as: GNU GCC compiler, you can run the following command:

$ sudo yum install gcc

or

$ sudo yum groupinstall "Development Tools"

If you are using the Ubuntu or Debian Linux, you can use the following command to install GNU GCC compiler:

$ sudo apt-get update
$ sudo apt-get install build-essential
