Building

Prerequisites:

0. get meson from pip. Do not use ubuntu package, it is too old.

1. get godot: https://docs.godotengine.org/en/stable/contributing/development/compiling/index.html

2. get clang 18+

   wget https://apt.llvm.org/llvm.sh
   chmod +x llvm.sh
   ./llvm.sh 18 all
   

   Without 'all' it will not install libc++

   To register it with update-alternatives on ubuntu, use this script: https://gist.github.com/junkdog/70231d6953592cd6f27def59fe19e50d

3. Build it with following options: scons platform=linuxbsd use_llvm=yes arch=x86_64 linker=lld cxxflags="-stdlib=libc++" linkflags="-stdlib=libc++"

4. Install ninja

   aptitude install ninja-build
   

Building project

Make build dir

meson setup --native-file clang.native.ini --prefix ABSOLUTE/PATH build

where ABSOLUTE/PATH is absolute path to the following subfolder: ui/godot/project

Then build as usual

cd build
ninja .

Then install compiled library

cd build
meson install --skip-subprojects
