As the title reads, the copy of <expected> in gtk3-libwebrtc configuration's libstdc++ is guarded behind __cpp_concepts >= 202002. This is a problem because clang 18 is compliant (with C++23) but unfortunately cannot be used to build code using std::expected. - https://github.com/llvm/llvm-project/pull/87998 - https://www.reddit.com/r/cpp/comments/1b6f3s4/comment/ktbkwze/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button
