What's your cpu? I can reproduce with an old xeon, but all my other machines pass the test fine.

At this step it has stopped. Tried several times. Tried on a new install as well.

The previous version ( was installed without any such difficulty.

[Edit] The issue mentioned above happens on both 0.5.22 and 0.5.23. Any workarounds will be appreciated as it is urgent.

Parallel build fails here as well, adding MAKE_NB_JOBS=1 to _config solves it.

/usr/bin/ld: ../libopenblas_skylakexp-r0.3.22.a: member ../libopenblas_skylakexp-r0.3.22.a(saxpy.o) in archive is not an object

Changing options to options=(!emptydirs !makeflags !buildflags) solves the problem.

i can confirm - parallel build fails also for me (on a 5950x):

workaround working for me:

make -j1 ${_config} libs netlib shared

Building 0.3.22 fails for me when parallel build is enabled (I have -j20 set as part of my MAKEFLAGS in makepkg.conf). The build process fails with either "bus error" or the attempt to allocate petabytes of memory. I had to add "-j1" to _config to make it build.

There is a bug report from February sounding a bit like this but it is supposed to be fixed already:

Hi there! As I have been suggesting to all scientific packages to date, it would be very beneficial to also include FFLAGS//FCFLAGS on the PKGBUILD. Something along the lines of if defined FFLAGS on the environment (within makepkg), then FFLAGS=${FFLAGS}, else use $CFLAGS (for example)

sha256sum is still the same for me. I'm curious if you use this address:, is the sha256sum the same?

Cebtenzzre commented on 2022-01-27 21:09 (UTC)

The sha256sum of the patch changed. It is now 972aa53d2fbbe76b46a1cd1a9e53ddfeb42968e701e0cb8894a5bc3c1072847d.
