How to build the latest?

[Tatsh]

The latest version needs C++ module support in a version 17 of LLVM/Clang it seems?

Even if I use the binary, it mentions .so files I do not have on my machine. You would either have to make all of that static or have a way to build without module support.

That's work in progress.

Ok. Latest version I can build is 128.

I was able to build with Clang 16 (with libcxx installed) like so:

cmake -DCMAKE_CXX_FLAGS='-ggdb -march=native -mtune=native -pipe -ftree-vectorize' -G Ninja -Wno-dev '-DCMAKE_EXPERIMENTAL_CXX_SCANDEP_SOURCE=${CMAKE_CXX_COMPILER_CLANG_SCAN_DEPS} -format=p1689 -- <CMAKE_CXX_COMPILER> <DEFINES> <INCLUDES> <FLAGS> -x c++ <SOURCE> -c -o <OBJECT> -MT <DYNDEP_FILE> > <DYNDEP_FILE>'
ninja

Do not include optimisation flags like -O2 or it will fail with the following:
