Example getting C++ modules working with clang>=18
If you don't have the latest LLVM with LIBCXX_INSTALL_MODULES=On configured
as an explicit option, I provide an ArchLinux PKGBUILD which can be used. You
can also inspect this PKGBUILD file if you want to build LLVM yourself
(regardless of your Linux distribution)
- a modern LLVM+Clang configured with
LIBCXX_INSTALL_MODULES=On(>=18 rc1) - CMake >= 3.28
- Ninja (you must use ninja -- Unix Makefiles will absolutely not work)
cmake -GNinja -Bbuild -DCMAKE_CXX_COMPILER=/path/to/modern/clang++
cmake --build build
