Setup and installation of GHDL
Even though GHDL is generally available in linux distributions package system, SpinalHDL depends on bugfixes of GHDL codebase that were added after the release of GHDL v0.37. Therefore it is reccomended to install GHDL from source. The C++ library boost-interprocess, which is contained in the libboost-dev package in debian-like distributions, has to be installed too. boost-interprocess is required to generate the shared memory communication interface.
sudo apt-get install build-essential libboost-dev git
sudo apt-get install gnat # Ada compiler used to buid GHDL
git clone https://github.com/ghdl/ghdl.git
sudo make install
Also the openjdk package that corresponds to your Java version has to be installed.
