- Build PPC64LE libraries with the lastest gcc available to
take advantage of instruction sets in later CPUs used in
the CPU specific kernels (jsc#SLE-18143, bsc#1197721).
For fortran use the stock compiler to avoid compatibility
issues between different versions of libfortran.
This is relevant for Leap/SLE only. It may be dropped once
gcc < 10 is no longer supported.
- Do the same for x86_64 on SLE to make sure Cooperlake support
is built properly.
- Remove:
* Do-not-attempt-to-check-host-CPU-if-TARGET-is-set.patch
* Create-independent-kernel-Makfile-configuration-when-building-DYNAMIC_ARCH.patch
* For-DYNAMIC_ARCH-don-t-use-sbgemm_r-as-parameter.c-doesn-t-get-build.patch
Instead, add from upstream:
* Define-sbgemm_r-to-fix-DYNAMIC_ARCH-builds.patch
* Remove-extraneous-and-wrong-definition-of-sbgemm_r-on-x86_64.patch
* Fix-checks-for-AVX512-and-atomics.patch
* Revert-AVX512-capability-check-from-PR-1980-moved-to-build.patch
* Use-CC-and-full-command-line-instead-of-hard-coding-gcc-for-AVX512-checking.patch
* Utilize-compiler-AVX512-capability-info-from-c_check-when-building-getarch.patch
- Update to v0.3.20:
* general:
some code cleanup, with added casts etc.
fixed obtaining the cpu count with OpenMP and OMP_PROC_BIND unset
fixed pivot index calculation by ?LASWP for negative increments other
than one
fixed input argument check in LAPACK ? GEQRT2
improved the check for a Fortran compiler in CMAKE builds
disabled building OpenBLAS' optimized versions of LAPACK complex SPMV,

Please, update to OpenBLAS to 3.17, as some optimizations were causing segfaults and reverted. See: https://github.com/xianyi/OpenBLAS/blob/develop/Changelog.txt.
It seems that octave 6.3.0 build failures (on test phase) may be associated to this on Tumbleweed.
OK, this really needs a better explanation. I have Tumbleweed and Leap 15.3 installed on different computers, and on both of them I use the Science repo to provide some more packages I need. Downgrading to default versions (3.13 on Leap and 3.14 on Tumbleweed) fixes the problem with Octave, as I was able to build version 6.3 and also run the tests (make check-local) without unknown failures. It probably affects other numerical packages too.

Hi,
Now it is something less trivial (or, perhaps, more). Julia version 1.8.5 (and probably some older versions of 1.8.x series too) needs integer indexes of vectors and matrices to be 64 bits, that means, there is a need to build adjusted "flavors" of some libraries.
For openBLAS, the "flavored" version must be compiled with "INTERFACE64=1" option.
Of course, other libraries that are linked against openBLAS will need "flavored" versions too. SuiteSparse, qrupdate, sundials and arpack-ng, at least.
The relevant sources of information are: https://docs.octave.org/v7.3.0/Compiling-Octave-with-64_002dbit-Indexing.html https://savannah.gnu.org/bugs/?57771 https://github.com/Reference-LAPACK/lapack/issues/666
On my computer, I built "proto" packages with the needed adjustments, but, of course, the "ideal" way is to have an established standard for package and libraries names.
It should be noted that, once "flavored" libraries are built, not only we will be able to build Julia but also a special version of Octave.
May I collaborate with the effort to make it happen, let me know.
OK, I will fork the current project so that my modifications can be debated. Still, I have one doubt, how do I pass a definition to rpmbuild when using build.opensuse.org infrastructure?
What I mean is that, on my computer, to generate the binary package with 64 bits indexes, I use: rpmbuild --define "index64 1" openblas.spec
I have no idea how to do this under build.opensuse.org.
Branched. Will do the same on SuiteSparse, arpack-ng, qrupdate and sundials, but would appreciate if I get an input about what may be the best practices, names and definitions to be used, or if it seems to be OK the way I did.
