I'd like to know how to compile with this version of GCC from Github:

https://github.com/parmance/par_offload

I've cloned it in my directory but I'm new to Ubuntu and don't know how to install and use from Github. There's no src directory to call make from.

  Shouldn't the Makefile in the main directory be what you want?

  "par_offload" is a gcc version. See 2.2 System Requirements linuxfromscratch.org/lfs/downloads/stable/… .... Building "par_offload" : cd [folder-with-par_offload] && mkdir build-par_offload && cd build-par_offload/ && ../par_offload/configure --prefix=/usr/local/gcc82 --program-suffix=82 --enable-languages=c,c++ --disable-multilib --disable-libstdcxx-pch && make && sudo make install

  @Knud Larsen after trying out your answer , I did manage to build this version of gcc. However , when trying to compile MyFile.cc with g++ -std=c++17 -fpar_offload MyFile.cc -o MyFile I get the error "-fpar_offload not found , did you mean -foffload" . Does this occur because I need something else installed or because of the par_offload gcc?

  The version appears to be gcc version 9.0.0 20180509 (experimental) (GCC). ... (I guessed on 8.2.0) . ... I renamed to /usr/local/gcc82/bin/gcc9, g++9. My OK "test command" is $ g++9 -std=c++17 -fpar-offload cc-new.cc, (where "cc-new.cc" is my test file.) Note : Do not use g++ but g++-[new-name]. ... Note2 : No underscore in option "-fpar-offload".

GCC, the Ubuntu build prerequisites are :
sudo apt install g++ autoconf libtool gawk flex bison binutils-dev libelf-dev libmpfr-dev libgmp-dev libmpc-dev texinfo

Prepare the OS for a "gcc build" : Make /bin/sh a link to bash → cd /bin/ && sudo rm -f sh && sudo ln -s bash sh

Build the "experimental par_offload gcc-9.0.0" : gcc requires a build directory outside the source code directory ....

cd [folder-with-par_offload] 
mkdir build-par_offload 
cd build-par_offload/ 
../par_offload/configure --prefix=/usr/local/gcc9 --program-suffix=9 --enable-languages=c,c++ --disable-multilib --disable-libstdcxx-pch
make
sudo make install 
cd /usr/bin/
sudo ln -s /usr/local/gcc9/bin/gcc9
sudo ln -s /usr/local/gcc9/bin/g++9

My "OK test command" is $ g++9 -std=c++17 -fpar-offload cc-new.cc, (where "cc-new.cc" is my test file.) : The file a.out is created.
