GCC Build Docker for Ubuntu

GCC 12

Build gcc-12/amd64 for Ubuntu 20.04

Run the following command to build gcc-12/amd64:

cd amd64/gcc-12-ubuntu
docker build -t gcc-12.2.0:ubuntu-20.04 .
docker run --rm --entrypoint cat gcc-12.2.0:ubuntu-20.04 /gcc-12.2.0-1-ubuntu-20.04.deb > /tmp/gcc-12.2.0-1-ubuntu-20.04.deb

Install

Now you can install it:

sudo apt install -y /tmp/gcc-12.2.0-1-ubuntu-20.04.deb

Set gcc-12 as high priority:

sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-12 12
sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-12 12

For convenience, add /usr/lib64 to LD_LIBRARY_PATH environment:

export LD_LIBRARY_PATH=/usr/lib64:$LD_LIBRARY_PATH
echo "export LD_LIBRARY_PATH=\"/usr/lib64:\$LD_LIBRARY_PATH\"" >> ~/.bashrc
