Build GCC from source [GCC v12.2.0]

In this article, we have presented the steps to build any version of GCC from source and install it.

Table of contents:

1. Step 1: Get source code of GCC
2. Step 2: Configure GCC
3. Step 3: Build and Install GCC
4. Complete steps

Step 1: Get source code of GCC

Clone the source code of GCC using this command:

git clone https://github.com/gcc-mirror/gcc.git
cd gcc

Checkout to the version you need. If we need the version 12.2.0, then the command is as follows:

git checkout releases/gcc-12.2.0

Skip the above step if you want to build the latest version of GCC.

Step 2: Configure GCC

To configure the GCC to build the desired features, use the following command:

./contrib/download_prerequisites
cd ..
mkdir objdir
cd objdir
$PWD/../gcc-12.2.0/configure --prefix=$HOME/GCC-12.2.0 --enable-languages=c,c++,fortran,go

If you want to build the compiler for only C programming language, the last command is updated as follows:

$PWD/../gcc-12.2.0/configure --prefix=$HOME/GCC-12.2.0 --enable-languages=c

Step 3: Build and Install GCC

To build GCC from source after configuration, use the following command:

make -j
make install

Once done, restart the session and check the version of GCC using the following command:

gcc --version

Complete steps

Following is the complete compiled steps to build GCC version 12.2.0 from source:

git clone https://github.com/gcc-mirror/gcc.git
cd gcc
git checkout releases/gcc-12.2.0
./contrib/download_prerequisites
cd ..
mkdir objdir
cd objdir
$PWD/../gcc-12.2.0/configure --prefix=$HOME/GCC-12.2.0 --enable-languages=c,c++,fortran,go
make -j
make install

With these steps in this article at OpenGenus, you must be able to build and install any version of GCC.
