Hello,
I am working on a Mac build of Octave 3.4.0. It's almost complete: it passes 6908 tests, has 2 known failures, and 5 unexpected ones. All of these five are due to the same issue, an exception inside SLATEC: "Chebyshev series too short for specified accuracy". I don't know Fortran and I'm not sure how to best debug the issue. The compilers I am using are gcc and gfortran 4.2.1.
Any ideas?
Best regards,
Camillo Lugaresi
I've not seen this error.
Where did you get your gfortran?
http://r.research.att.com/gfortran-42-5664.pkg
What dependencies did you install?
All, except for gnuplot and ghostscript.
What was the result of running /configure? (it gives a summary at the end)
Finally, please copy-n-paste the actual error.
I'll attach the configure summary and the output of make check. I'm throwing in fntests.log as well.
Thanks,
Camillo

There may be another problem, but since you're building a 64bit app you'll need to take care of a bug in Apple's blas. The problem is discussed in the developer's copy of README.MacOS http://hg.savannah.gnu.org/hgweb/octave/file/64ae43e0e1c0/README.MacOSThere is a patch intended for the developer's sources at the link below that will allow the configure script to detect the problem and apply the wrapper. https://savannah.gnu.org/patch/?7468
I didn't know that there were issues with LAPACK routines as well. Do you have a test case?
CL No I don't. I've only been reading along on the developer's mail-list.
I'll forward the link to those working on the wrapper which has been submitted to the Octave patch tracker.
Ben
Thank you. Should I subscribe to that mailing list as well? Apart from those 5 test failures, I think I put together a pretty nice Mac build of Octave. Perhaps it could be useful to others.
