Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.

@martin-frbg, all unix builds fail with:

make[1]: *** No rule to make target 'cspmv.o', needed by 'libs'.  Stop.

Where should this object file be coming from? 🤔

[martin-frbg]

interface/zspmv.c - maybe your download of the source tarball was truncated ?

[isuruf]

@martin-frbg, it seems like there are two different code patterns

ifneq ($(NO_LAPACK), 1)

and

ifndef NO_LAPACK

We have NO_LAPACK=0 in the build script here which works fine with the first pattern, but is not for the second pattern.

[martin-frbg]

Eh, thought the unqualified ifdefs had died out already, and no recent change in this function (though the interval for this release was definitely too long)

[martin-frbg]

Ok, I see I added them myself two months ago :(

[h-vetinari]

Thank you both! Seems the patch I came up with here is working, so I opened https://github.com/xianyi/OpenBLAS/pull/3972.

[h-vetinari]

Hm, seems osx-arm64 cross-compilation is unhappy as well...

Copying the static library to $PREFIX/lib
install: libopenblas_sandybridgep-r0.3.22.a: No such file or directory
make[1]: *** [Makefile.install:66: install] Error 71

[martin-frbg]

You'll need my 3975 on top of your patch, but it is now looking as if there is something else broken in 0.3.22 - maybe "just" corner cases of ZGETF2 plus a few changed accuracies from LAPACK 3.11.0, maybe more. I'll probably release 0.3.23 as soon as the dust settles.

[martin-frbg]

now you'd need PR 3980 for the regression in GETF2 as well, may make sense to wait for 0.2.23 unless you want to support checking 0.3.22 for further defects

I don't mind backporting / testing further until we're sure that all things are sorted out for 0.3.23 (PR 3980 needed 3978 as well).

osx-arm still unhappy...

Copying the static library to $PREFIX/lib
install: libopenblas64__sandybridgep-r0.3.22.a: No such file or directory
make[1]: *** [Makefile.install:71: install] Error 71

[martin-frbg]

how come osx-arm is named sandybridge ? Is the install step not repeating the build arguments (and thus going with an autodetect of the build host) ?

We didn't change the build instructions since 0.3.21 (where this didn't happen), so either we were implicitly relying on something undocumented, or something broke.

[martin-frbg]

Well, the build is undoubtedly for an ARM64 system (using kernels from the arm64 subtree and culminating in the success message mentioning libopenblas64_vortexp as the name of the library. But the subsequent make install you are attempting appears to lack all parameters, so no concept of cross-compile or -target exists and getarch is run again to identify the build host. This step has never been automated, and in fact a warning is printed at the end of compilation that you need to repeat the exact same set of compile arguments in the install step.

[martin-frbg]

released 0.3.23 now with the fixes (plus a few Raptor Lake cpuids)

[h-vetinari]

Cross-compilation still unhappy in #151; I don't have time to look at it this week.

[h-vetinari]

Superseded by #151
