Hmm, probably some change octave 2.1.50 and octave-2.1.57. Happens on 2.1.62... It's not so simple as a change in octave between versions. I tried removing the 2.1.57 rpm and installed the 2.1.50 rpm and it still doesn't work on Fedora 3 (but does work on Fedora2). Could this be a library problem? Yes; I actually tried on 2.1.62 and 2.1.50. I think it's a problem in the lapack library. I think it's lapack problem. *** This bug has been marked as a duplicate of 138447 *** Changed to 'CLOSED' state since 'RESOLVED' has been deprecated. |
