:: failed to verify openblas-lapack integrity

Ah, false alarm. I ran it again, giving it a bit more time, and eventually it did successfully complete.

When I try to build this, I get a seemingly endless hang with 100% CPU usage at the following lines, which I think are some sort of build test:

rm -f ?BLAT3.SUMM
OMP_NUM_THREADS=2 ./sblat3 < ./sblat3.dat
rm -f ?BLAT2.SUMM
OMP_NUM_THREADS=2 ./sblat2 < ./sblat2.dat

I left it running for a full hour and it never made any progress past there. So I killed those two processes, at which point makepkg quit with

/bin/sh: line 1: 31772 Killed OMP_NUM_THREADS=2 ./sblat3 < ./sblat3.dat
Makefile:59: recipe for target 'level3' failed
make[1]: *** [level3] Error 137
make[1]: *** Waiting for unfinished jobs....
/bin/sh: line 1: 31779 Killed OMP_NUM_THREADS=2 ./sblat2 < ./sblat2.dat

Makefile:111: recipe for target 'tests' failed
make: *** [tests] Error 2
==> ERROR: A failure occurred in build().

==> ERROR: Makepkg was unable to build openblas-lapack.

Is there something I should be doing differently, or is this known already?

On my PC, I tested that 2.9 is much slower, 20%~25%, than 2.8.

@Xyne
I have updated the PKGBUILD to let it provide itself. :)

There is already a discussion in openblas package. gborzi, the maitainer, prefers to keep openblas as simple as possible.

Hi,

The package should also "provide" openblas if it provides all of the same functionality (and more).

Have you discussed merging your optimizations into the openblas package?

Regards,
Xyne

This package is based on gborzi's openblas. openblas does not work as "drop in" as I expected. Thus, I enabled lapack and cblas within openblas.

This version works with Xiao0er's python2-numpy-openblas
