fatal error: too many errors emitted, stopping now [-ferror-limit=]

I prepared a copy of llvm-clang-Darwin-arm64-16.0.0. I think the clang version should be consistent with the system, but the error is the same. It seems that the basic definition header file cannot be found and the compilation cannot be completed.

Try update your os and xcode command line tools to latest, and rerun xcode-select, cause last github action show macos build is ok.

I saw you updated llvm, and now I can build the project on macos 15, thank you very much!

However, I encountered a new problem, it seems that only the Editor target cannot use lsp properly, if I turn off CMAKE_UNITY_BUILD for this target, everything works fine. I haven't been able to find the problem, this solution can only be my temporary measure.

[FlyAndNotDown]

What means is lsp ? I tried build in Windows / macOS, build is OK.

[justforlxz]

lsp is a language server. I use vim to develop projects and need to use lsp to provide c++ jump, type reminder and other functions.

build is ok, only lsp not working. It seems to be related to compile_commands.json. If CMAKE_UNITY_BUILD=OFF, there will be every cpp compilation command in json, but if it is ON, there will only be unity-related ones.

I checked some information and it seems that clangd does not support it yet. It doesn’t matter. I can solve it locally.

[justforlxz]

My problem has been solved.
