Hi! This is the friendly conda-forge automerge bot!

I considered the following status checks when analyzing this PR:

• linter: passed
• azure: failed

Thus the PR was not passing and not merged.

Interesting, something is causing ninja install in install_llvm.sh to repeat the full build from build.sh.

I remember that this happened before in clangdev, where this was caused/fixed by:

@isuruf: I marked as clang_bootstrap 11.rc builds as broken to avoid different compilers in top level build vs output level build envs which caused make to recompile.

This would seem to point to the merge of https://github.com/conda-forge/clang-compiler-activation-feedstock/pull/91 as the culprit, but the compilers are actually the same between build.sh and the libllvm16 output:

build.sh:

    clang_bootstrap_osx-64: 14.0.6-h6ddedbb_4         conda-forge
    libcxx:                 14.0.6-hccf4f1f_0         conda-forge

libllvm16:

    clang_bootstrap_osx-64: 14.0.6-h6ddedbb_4         conda-forge
    libcxx:                 15.0.7-h71dddab_0         conda-forge

I'm not 100% if that's causing it, but what did stand out was a difference in the libcxx being pulled in (https://github.com/conda-forge/libcxx-feedstock/pull/108 was merged after #198).

@isuruf, if you have an idea what's going on here, your input would be much appreciated.

Did you run a verbose ninja build?

So ninja --verbose install doesn't give much more info (aside from spelling out the full call), it just starts recompiling immediately:

+ cd build
+ ninja --verbose install

(note I didn't shorten the lines; the ... at the end is how they appear in azure for osx-arm)
