[Octave-bug-tracker] [bug #45659] version function: options and return values supported by Matlab

[Mike Miller]

Follow-up Comment #46, bug #45659 (project octave):

With Debian unstable with ATLAS, OpenBLAS, and reference BLAS all installed
together, I get


>> check_blas_ver
ans = OpenBLAS (config: NO_LAPACKE DYNAMIC_ARCH NO_AFFINITY Haswell)



I think you may have a misconfiguration on your system Markus. Octave will
certainly build against any of these options. It looks like you have
configured Octave (maybe intentionally, maybe not) to build against ATLAS, but
you may have OpenBLAS installed and set up to be the default BLAS
implementation.

On my system,
