Please stage together with https://build.opensuse.org/request/show/1153127!
Currently, openSUSE:Factory:Staging:E.

- Remove DYNAMIC_LIST for aarch64 for older gcc versions: This has
  been fixed upstream.

- Update to version 0.3.26:
  * General:
    - Improved the version of openblas.pc that is created by the
      CMAKE build.
    - Fixed a CMAKE-specific build problem on older versions of
      MacOS.
    - Worked around linking problems on old versions of MacOS.
    - Corrected installation location of the lapacke_mangling
      header in CMAKE builds.
    - Added type declarations for complex variables to the
      MSVC-specific parts of the LAPACK header.
    - Significantly sped up ?GESV for small problem sizes by
      introducing a lower bound for multithreading.
    - Imported additions and corrections from the Reference-LAPACK
      project:
      + Added new LAPACK functions for truncated QR with pivoting
        (Reference-LAPACK PRs 891&941).
      + Handle miscalculation of minimum work array size in corner
      	cases (Reference-LAPACK PR 942).
      + Fixed use of uninitialized variables in ?GEDMD and
      	improved inline documentation.
      + Fixed use of uninitialized variables (and consequential
      	failures) in ?BBCSD.
      + Added tests for the recently introduced Dynamic Mode
      	Decomposition functions.
      + Fixed several memory leaks in the LAPACK testsuite.
      + Fixed counting of testsuite results by the Python script.

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.


Andre Barros's avatar

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.
