1 week ago What are your requirements in terms of supported clang/libc++ versions? I think the code uses some modern features (C++20 and higher) that your library version does not support.
Interestingly, I cannot compile master either but for a different reason. It seems some code is missing.

1 week ago I just tested it with the same version (clang 14) and got the same problems. However, it works if I use 15.0.0 version preinstalled on my Mac:
Apple clang version 15.0.0 (clang-1500.3.9.4)
Target: arm64-apple-darwin23.6.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/binI'm not sure if this is really a problem of outdated Clang or an outdated libc++. Is it possible for you to test Clang 15?

1 week ago The compiler does not seem to be the problem (I assume the warnings are harmless), maybe the library

1 week ago No ... The above shows the output of running cmake -DCMAKE_BUILD_TYPE=Release -S . -B ./build ... I.e. I have clang 15 now. However running cmake --build ./build --target rat -j 10 still fails due to e.g. "format file not found"

1 week ago I see. I think on Linux, the compiler always uses libstdc++ as standard implementation which is not provided by Clang and thus upgrading Clang doesn't change anything. It seems to be not so trivial to upgrade libstdc++ without also upgrading the Ubuntu version though.
However, Clang provides libc++ which you might be able to use by passing -stdlib=libc++ to the compiler (e.g., by adding it to CPPFLAGS).

1 day ago This did not help much. After running cmake -DCMAKE_BUILD_TYPE=Release -S . -B ./build, I manually edited build/CMakeCache.txt and set CMAKE_CXX_FLAGS:STRING=-stdlib=libc++. But now It complains about several other things
