Build failure locally

I'm trying to do a clean build for the compiler but it's failing.

The first failure is related to building the early-swift-driver. I'm trying to build with the following command.

utils/build-script --skip-build-benchmarks \
  --skip-ios --skip-watchos --skip-tvos --swift-darwin-supported-archs "$(uname -m)" \
  --sccache --release-debuginfo --swift-disable-dead-stripping --test

But I'm getting the following error.

Building Swift Driver dependency: llbuild
CMake Error at /usr/local/Cellar/cmake/3.22.2/share/cmake/Modules/CMakeTestCXXCompiler.cmake:62 (message):
  The C++ compiler

    "/usr/local/opt/llvm/bin/clang++"

  is not able to compile a simple test program.

  It fails with the following output:

I tried to build without using the early-swift-driver so I tried to build with the same command but added --skip-early-swift-driver at the end. I got another error:

I'm not sure what's the problem. Does anyone know how to solve these issues?

This seems like you have llvm binaries installed in your machine which is llvm clang and cmake is selecting it to compile thing instead of apple clang which ships with Xcode. For example when you run a command ./swift/utils/build-script --release --skip-build-benchmarks --swift-darwin-supported-archs "$(uname -m)" --sccache --skip-ios --skip-tvos --skip-watchos it should appear in the logs:

-- CMake (/opt/homebrew/Cellar/cmake/3.22.2/bin/cmake) Version: 3.22.2
-- CMake Make Program (/opt/homebrew/bin/ninja) Version: 1.10.2
-- C Compiler (/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang) Version: 13.0.0.13000029
-- C++ Compiler (/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang++) Version: 13.0.0.13000029

What does appear in your logs?
I'm not really sure this is the issue, but I'd give a try either specify the Xcode clang compiler... but not sure how to change it in the build script (you could take a look in those cmake variables CXX — CMake 3.23.0-rc2 Documentation), other option you could uninstall llvm binaries and try it, but that don't seem the correct one...

Hope that helps in some way =]

Haha. :smile: You're correct! I completely forgot about that! Thank you!
