Detailed steps on how to reproduce the bug

when llvm is installed through homebrew, and cmake uses the /opt/homebrew/opt/llvm/bin/clang compiler, juceaide fails to link.

What command are you running to get to that point?

I think you might need to report this to the juce team... Does juce build from the modules/juce submodule?

If not, does it build from the juce tip?

My process for compiling tracktion_engine is:

$ brew install llvm
$ cmake -DCMAKE_BUILD_TYPE=Debug -B build

I tried building juce:master and it compiled fine:

edw@goat ~/github/JUCE (master) $ which clang
/opt/homebrew/opt/llvm/bin/clang
edw@goat ~/github/JUCE (master) $ cmake . -B cmake-build -DJUCE_BUILD_EXAMPLES=ON -DJUCE_BUILD_EXTRAS=ON -DCMAKE_BUILD_TYPE=Debug

Hmm, I can't even get that far:

Can I ask how you're specifying cmake to use llvm?
For the above I used

export CPPFLAGS="-I/opt/homebrew/opt/llvm/include"
export CC=/opt/homebrew/opt/llvm/bin/clang
export CXX=/opt/homebrew/opt/llvm/bin/clang++

Sorry for the late response.
I'm doing:

export PATH="/opt/homebrew/opt/llvm/bin:$PATH"
export CC=clang
export CXX=clang++

I'm sorry but I can't get this to work either.

I can't even build juce as it can't seem to find the MacOS SDK libraries and frameworks, even though the -isysroot looks correct. If you get any further let me know but at the moment only AppleClang is officially supported on macOS I'm afraid.

It's all good. I was actually using homebrew llvm by accident, and was confused why it wasn't working.
AppleClang is perfectly capable.
