❯ clang --version
Apple clang version 15.0.0 (clang-1500.1.0.2.5)

scip-clang commit: 3035e46

The binaries that are build require rpath to be set:

❯ otool -L /private/var/tmp/_bazel_varun/556335f3782e99575c0c742955be4ea7/execroot/scip_clang/bazel-out/darwin_arm64-opt-exec-2B5CBBC6/bin/external/llvm-project/clang/clang-tblgen

        /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1336.61.1)

        @rpath/libunwind.1.dylib (compatibility version 1.0.0, current version 1.0.0)

But there is no LC_RPATH command in the output of otool -l

Consequently, there is a failure when attempting to run the binaries (here is an example)

  Reason: no LC_RPATH's found

I cannot quite tell what changed from before -- is libunwind missing from some system directory, is it not getting built for some reason, was LC_RPATH set before but it isn't being set now...

It looks like libunwind is present in the toolchain.

It looks like #461 should fix this to some extent (the CI build pipeline works for macOS - https://github.com/sourcegraph/scip-clang/actions/runs/8106024167), still need to figure out my local build.
