clang 12.0.0 -- ld: unsupported tapi file type '!tapi-tbd' in YAML file .../libSystem.tbd

[jakirkham]

• I read the conda-forge documentation and could not find the solution for my problem there.

Issue:

Have started seeing this recently with clang version 12.0.0 and python version 3.10. Did not see this issue when using clang version 11.1.0. Also not seeing this with python version 3.9 or earlier (though appear to be getting clang version 12.0.1 in those cases). Not sure why clang version 12.0.1 is not getting installed with python version 3.10.

ld: unsupported tapi file type '!tapi-tbd' in YAML file '/Applications/Xcode_13.2.1.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/lib/libSystem.tbd' for architecture x86_64

Details about conda and system ( conda info ):

Using conda-incubator/setup-miniconda@master

[jakirkham]

Forcing clang version 12.0.1 fixes the issue. That said, am unclear on why 12.0.0 is picked up instead of 12.0.1 in this case.

[isuruf]

Linked log shows ld64 being used from defaults. That was the issue.

Only conda-forge is specified here

Perhaps conda-incubator/setup-miniconda needs some other configuration we are missing

Edit: Looks like it is issue ( conda-incubator/setup-miniconda#207 )
