In the future, please use WikiFormatting, fill in the Port field and Cc the port maintainers (port info --maintainers octave), if any.

The issue is that, somehow, LAPACK is not being found. What does "port installed atlas" return?

If you haven't already, please try:

sudo port clean octave
sudo port selfupdate
sudo port upgrade outdated
sudo port install octave +atlas+gcc5+glgui+gui+qtgui

and see if that works. Sometimes cruft happens and cleaning it out works; sometimes not. Always worth a try. If this fails, then attach the new (whole, clean) build log to this ticket & post that you've added the attachment.

Thank you. Unfortunately this did not work and resulted in apparently the same error. I am attaching the new logs.

Thank you for this very useful suggestion. Indeed I had found atlas had been installed with +nofortran. So I was in a process of re-installing atlas with gfortran, which took more than 24 hours. After that octave configured and build without a problem, except a warning that arpack had been built with +accelerate and likely cause crash. So I am now trying to re-install arpack with +atlas, but that is a different story. Thank you again. A question, though, is why the port did not detect this atlas problem.

[michaelld (Michael Dickens)]

Good suggestion! I had no idea that atlas +nofortran would fail. I don't use atlas (too long to build; I use openblas instead). Can you test the patch I just attached to this ticket to see if it works for you with your "atlas +nofortran" port active?

Octave has undergone significant changes recently (r148698).
Any chance this issue has been resolved?

[MarcusCalhoun-Lopez (Marcus Calhoun-Lopez)]

With no further updates, let us assume this is now fixed.
If not, we can open a ticket specifically for octave 4.
