Add ALMA9 and install libc++ on debian-clang
- Add ALMA9 with clang v16 and LLD linker (not via CVMFS)
- Add libc++ (LLVM C++ STL) to
debian-clang
The idea is to build in both debian-clang
and alma9-cern
with LLVM's libcxx to ensure we can build both standard libraries. Requires adding -stdlib=libc++
to the compile arguments (maybe meson cpp_stdlib=libc++
works as well, needs testing).
