\"yumIn this tutorial, we will take a look at how to install GCC on CentOS 7<\/strong>. GCC or GNU Compiler Collection is released by the Free Software Foundation and as the name suggests, it is a very useful collection of programming compilers such as C, C++, Objective-C, Objective-C++, Fortran, Java, Go and Ada. GCC is an official compiler of the GNU operating system but also it is a standard compiler on many Unix operating systems such as Linux.\u00a0Installing GCC on CentOS 7<\/strong>, is really an easy task and it shouldn’t take more than 10 minutes.<\/p>\n

<\/p>\n

1. Update the server<\/strong><\/h2>\n

First of all log in to your CentOS 7 VPS via SSH as user root<\/p>\n

ssh root@IP_Address -p Port_number<\/pre>\n
and make sure that all installed packages on the server are up to date<\/p>\n
yum -y update<\/pre>\n
2. Install GCC from repository<\/strong><\/h2>\n
GCC can be easily installed from the official CentOS repositories. Run the following command to install GCC on your server<\/p>\n
yum -y install gcc<\/pre>\n
Once the installation is completed, you can the version of GCC installed on your server<\/p>\n
gcc --version\r\n\r\ngcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-16)\r\nCopyright (C) 2015 Free Software Foundation, Inc.\r\nThis is free software; see the source for copying conditions. There is NO\r\nwarranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.<\/pre>\n
As might be seen from the output, the GCC version distributed by CentOS 7 is 4.8.5 which is not the latest version of GCC.<\/p>\n
You may also want to install gcc-c++. It will automatically include the C++ library and compile files with extensions that indicate they are C source as C++, instead of as C.<\/p>\n
yum -y install gcc-c++<\/pre>\n
3. Install GCC from source<\/strong><\/h2>\n
If you need a newer version of GCC than the one distributed by the official CentOS 7 repositories you can install it from source.<\/p>\n
It is highly recommended to start a screen session before starting the installation. Run the following command<\/p>\n
screen -U -S gcc<\/pre>\n
Download the tarball of the GCC version you want to install. In our example we will use GCC version 7.3.0<\/p>\n
wget http:\/\/ftp.mirrorservice.org\/sites\/sourceware.org\/pub\/gcc\/releases\/gcc-7.3.0\/gcc-7.3.0.tar.gz<\/pre>\n
Unpack the tar archive and change the current working directory<\/p>\n
tar zxf gcc-7.3.0.tar.gz\r\ncd gcc-7.3.0<\/pre>\n
Install bzip2 and run the ‘download_prerequisites’ script to download some prerequisites needed by GCC. You have to run this from the top level of the GCC source tree.<\/p>\n
yum -y install bzip2\r\n.\/contrib\/download_prerequisites<\/pre>\n
Once the prerequisites are downloaded execute the following command to start configuring the GCC build environment<\/p>\n
.\/configure --disable-multilib --enable-languages=c,c++<\/pre>\n
Once it is completed, run the following command to compile the source code. It may take a few hours for the compilation to complete, so sit back and relax.<\/p>\n
make -j 4\r\nmake install<\/pre>\n
4. Verify GCC installation on CentOS 7<\/h2>\n
After the compilation process is completed. You can check if GCC is properly installed.<\/p>\n
gcc --version\r\n\r\ngcc (GCC) 7.3.0\r\nCopyright (C) 2017 Free Software Foundation, Inc.\r\nThis is free software; see the source for copying conditions.  There is NO\r\nwarranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.\r\n<\/pre>\n
