[Octave-bug-tracker] [bug #54179] sparse/eigs.m test failure on macOS

[Andrew Janke]

Follow-up Comment #3, bug #54179 (project octave):

Not sure if I'm using DYLD_INSERT_LIBRARIES right, but using it to pull in
OpenBLAS appears to have no effect:


$ OPENBLAS=$(brew --prefix openblas)
$
DYLD_INSERT_LIBRARIES=$OPENBLAS/lib/libblas.dylib:$OPENBLAS/lib/liblapack.dylib:$OPENBLAS/lib/libopenblas.dylib
octave
GNU Octave, version 4.4.0
...
Octave was configured for "x86_64-apple-darwin17.6.0".
...

octave:1> test eigs
***** testif HAVE_ARPACK
 A = toeplitz ([0, 1, zeros(1, 8)], [0, -1, zeros(1, 8)]);
 A = kron (A, eye (10)) + kron (eye (10), A);
 opts.v0 = (1:100)';
 opts.maxit = 5;
 warning ("off", "Octave:eigs:UnconvergedEigenvalues", "local");
 d = eigs (A, 4, "lm", opts);
 assert (d(3:4), [NaN+1i*NaN; NaN+1i*NaN]);
!!!!! test failed

  Location  |  Observed  |  Expected  |  Reason
