Can't build with `LLVM_BUILD_STATIC=ON`

[dustdfg]

When I start building I get following error:

CMake Error at cmake/modules/CheckCompilerVersion.cmake:88 (message):
  libstdc++ version must be at least 7.4.
Call Stack (most recent call first):
  cmake/config-ix.cmake:16 (include)
  CMakeLists.txt:949 (include)

But I use Fedora 41 and installed libstdc++-static libstdc++-devel libstdc++ packages. Trying to compile LLVM 19.1.16. As compiler use system provided clang clang++ lld

As far as I know fedora does not provide static glibc

But it complains about libstdc++ not about glibc

@Andarwinux thanks for pointing to glibc

Installing glibc-static helped. Not like compilation already finished but at least it started so I think issue can be re-clarified as misleading error message

CMake tests whether the compiler is working or whether a library or function is available by building an executable, but since you specify -static but do not have static glibc installed, all such attempts will fail, including attempts to detect the STL version provided by the C++ compiler.
You can use -DCMAKE_TRY_COMPILE_TARGET_TYPE=STATIC_LIBRARY to make CMake pass such tests without linking, but expect this will cause other things to not work. This option is often used to build low-level libraries with dependency loops such as compiler-rt.

It finished compilation. I think I am closing
