OpenBLAS 0.3.10_1 +native Build Fails on MacOS 10.15.6 and Xcode 12.0

[mascguy (Christopher Nielsen)]

After upgrading to Xcode 12.0 command-line tools, the OpenBLAS +native variant fails to build.

Perusing the log, it looks like it may be failing during the link phase. (Though please keep me honest, as I may be missing something.) Build log file is attached.

This error stands out:

:info:build ld: unsupported tapi file type '!tapi-tbd' in YAML file '/Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk/usr/lib/libSystem.tbd' for architecture x86_64

There's an outstanding ticket mentioning that error from 'ld', though it was logged two months ago. And it's not clear from the ticket whether the creator had one of the Xcode 12 Beta releases installed. (The official Xcode 12.0 release was just published on 9/17/2020, so they definitely weren't using the final version.)

In any case, here's the ticket, in case it's helpful:

ticket:60893

Let me know if you folks need any additional info.

p.s. My apologies for the uncompressed log file. I tried replacing it with a gzipped version, but the original wasn't removed.

Meanwhile, I can't seem to figure out how to remove an attachment. Am I simply getting old, or... ?

please show us the result of

port -v installed | grep ld64

Thanks!
