Fails to compile with clang11

[SpaceIm]

README claims that clang11 is supported, but when I try the basic example with clang11 on Linux, compilation fails:

Could you provide exact minimum supported versions of major compilers please (gcc, clang, msvc, apple-clang, though I guess apple-clang is not supported at all since it fails to compile even with latest version apple-clang 14 due to lack of std::ranges support)?

I will double check it later and update readme with specific versions of compilers, but CI works fine with clang-11
https://github.com/victimsnino/ReactivePlusPlus/actions/runs/3284620515/jobs/5410805522

-- The CXX compiler identification is Clang 11.0.0

[victimsnino]

Double-checked: clang-11 is possible to build RPP without any issues

[SpaceIm]

Do you link to libstdc++ or libc++?

[victimsnino]

manually - not. Just doing

export CC=clang
export CXX=clang++
cmake -B build -DRPP_BUILD_TESTS=1
cmake --build build --parallel 12

Closing due to inactivity and no way to reproduce it
