No issues at all.

And I looked my spec was:

openblas@0.3.29~bignuma~consistent_fpcsr+dynamic_dispatch+fortran~ilp64+locking+pic+shared build_system=makefile patches:=1a2401f symbol_suffix=none threads=none

and yours is:

 -       ^openblas@0.3.29~bignuma~consistent_fpcsr+dynamic_dispatch+fortran~ilp64+locking+pic+shared build_system=makefile patches:=1a2401f symbol_suffix=none threads=none arch=darwin-sequoia-m1 %c,cxx=apple-clang@17.0.0 %fortran=gcc@15.1.0

Those look the same.

I also saw that OpenBLAS 0.3.30 is out so I added that and installed and it worked as well. The PR is here:

#754

Perhaps you can try that version?

When I tried again, it is now installing v0.3.30 but I get the same error

What am I doing wrong ?

So, well, that's identical.

And it just installed on my home laptop as well.

My only other thought is libLTO.dylib isn't installed? I mean I see:

❯ find /Library/Developer/CommandLineTools/ -name libLTO.dylib
/Library/Developer/CommandLineTools/usr/lib/libLTO.dylib

I might need to invoke the name of @haampie and see if he knows anything (or if he can refer us to someone).

[cpraveen]

I do have the libLTO.dylib file.

[mathomp4]

Well I am stumped. It must be some sort of difference in environment or setup, but my Spack setup is fairly stock and my environment (while admittedly crazy) isn't that crazy in regards to Spack. The most exciting thing I have set is SPACK_SKIP_MODULES=1 which, well, does nothing with this.

[Chrismarsh]

I'm not seeing this problem on aarch64, but a colleague is seeing this on x86_64 mac.

Is that the difference here? lll these patches fixing it are guarded behind aarch64 conditionals, so I am wondering if they should be, but aren't, being applied on x86_64 macos and that is what is causing the difference?

[cpraveen]

I still get this error on arm macs, and I switched to netlib-lapack.

[Chrismarsh]

@cpraveen do you have xcode installed, which reports version 26 (pkgutil --pkg-info=com.apple.pkg.Xcode)?

In the make file
https://github.com/OpenMathLib/OpenBLAS/blob/993fad6aebbce34a97d3f8c34d6d79d35b64cc48/Makefile.system#L441

this check obtains xcode = 26, and never tries the CLI tools, which reports 16.
Thus the lto fix is never applied, and thus it fails.

I only have CLI tools installed, which picks up version 16 and thus the fix is applied. I bet @mathomp4 also only has the cli tools installed.

Currently testing this and if this is the problem I will submit a PR for spack and upstream

[Chrismarsh]

As well, I can't find INTERPROCEDURAL_OPTIMIZATION enabled in the cmake builds which is also be a confounding factor as that's confirmed to build no problem.

[mathomp4]

@Chrismarsh well nuts. I now see this:

  >> 12533    make: *** [Makefile:176: tests] Error 2

it's a bit mangled, but it's the same thing.

I just tried installing OpenBLAS 0.3.30 with spack using GCC 15.2 and I get that error.

And I do have the latest xcode installed:

❯ xcodebuild -version
Xcode 26.0.1
Build version 17A400
