[Octave-bug-tracker] [bug #54276] Linking issues

[John W. Eaton]

Follow-up Comment #9, bug #54276 (project octave):

I'm not sure, but the errors seem to indicate that liboctave is not properly
linked with the lapack and blas libraries.

Was liboctave relinked after you reconfigured with the


LDFLAGS=-L/work/logiciels/rh7/lapack/3.6.1/lib --with-lapack=-llapack
--with-blas=-lblas


options?

What happens if you delete liboctave/liboctave.la and run make again?  I see
the following output for relinking liboctave on my system:

Note that in the link command includes -llapack and -lblas.  What happens for
you?
