Advice on MacOS development environment? (ld: library not found for -Lsystem)

[Nathan Martinez]

Hi guys - I'm setting up a MacOS dev environment to work on ClickHouse. Trying to do the steps here (specifically, cmake -G Ninja -DCMAKE_BUILD_TYPE=RelWithDebInfo -S . -B build) throws the error ld: library not found for -lSystem.

Any advice to work around this? I've read online that the LIBRARY_PATH, LD_LIBRARY_PATH, or DYLD_LIBRARY_PATH variables may help ld find the needed libraries, but I can't get it to work.

Anyone have advice beyond the ClickHouse MacOS setup doc for setting up their MacOS environment? Would love to just copy someone's setup.

Things I already did to setup my dev env:

1. Installed everything from the brew install... step here
2. Do the PATH, CC, and CXX environment variables from this step
3. Confirm LLVM clang is being used instead of Apple clang (already got around that error)

Full compiler output:

ClickHouse % cmake -G Ninja -DCMAKE_BUILD_TYPE=RelWithDebInfo -S . -B build

Thanks in advance.

Also, anyone have advice on configuring CLion on MacOS so code navigation works well? Thank you again.
