[Octave-bug-tracker] [bug #42760] configure deteced libqrupdate cannot locate libblas.so.0, octave build anyway

[John W. Eaton]

Follow-up Comment #6, bug #42760 (project octave):

I don't think there is enough detail in this report for me to understand what
is really happening.

It appears that somehow you no longer have libblas.so.0 on your system, but
some library is still linked to it.  Perhaps that is a packaging bug?  Or some
library that Octave is linked with that uses libblas.so.0 was not removed when
libblas.so.0 was removed from your system?

When did you remove libblas.so.0?  Before or after configuring and building
Octave?

Are the Octave libraries linked directly with libblas.so.0?  I think you would
have to look at the link commands for liboctave, liboctinterp to see as ldd
seems to just report the full list of all libraries that are linked, even if
not directly.

Is some other library linked directly with libblas.so.0?  What does ldd tell
you if you ask for the list of libraries linked to the arpack and qrupdate
libraries?
