Has anyone successfully built Octave on a machine with OSX 10.7 installed. I attempted to do this with Octave 3.4.2 using MacPorts. The error I got does not seem to me to be a problem with the portfile, but with the build process. The log file error message was:

I did successfully use the same port command to install octave on a different machine running snow leopard. This installation still runs fine after upgrading to lion (OSX 10.7).
Liam, I'm seeing the same error when I attempt to build Macports' octave-devel on OSX 10.7. I've seen similar errors in the past, which those with an understanding of c/c++ have often fixed very quickly for me. Eventually, I'll search through the mail-list to find one of those past examples. Perhaps it will be clear from that what needs to be done. I'm in the middle of upgrading my computer, so I don't know when I'll get to it.
Apparently the error is due to Apple's Carbon framework.
I've been using Carbon for FLTK, and my impression is that we'll need Carbon for the Qt stuff. Thus, I assume all MacOS users will eventually be impacted.
A discussion of the same problem by developers of OpenSceneGraph is at the link below.
Looks like a solution is possible, but it is beyond my skill set.

--without-framework-carbon \ to the list of configure options in the portfile downloaded by my previous attempt to install octave-devel. I found the portfile in q slightly different location than listed by Sebastian; mine was at: /opt/local/var/macports/sources/rsync.macports.org/release/ports/math/octave-devel/Portfile Anyway, with this change it did build Octave 3.4.2 64 bit successfully using the gcc 4.5 compiler set. I was wondering about the qt stuff. I didn't know about the OpenSceneGraph discussion, but I did look up Apple's instructions on how to deal with the deprecated method and it didn't look like it would be hard for someone with the proper 'skill set."
When I do start up octave, I get a warning that no graphical display was found. But plotting works fine both with gnuplot and fltk. When I go to print or save a graph with fltk, I get warnings that fig2dev, epstool, and pstoedit are not available. I don't know what these are needed for; I always print/save to pdf which works fine without them. I installed the latter two separately with MacPorts which eliminated two of the warnings. Macports doesn't have a fig2dev port, but I'm going to try to install if from source when I get a chance.
Ben, there are a couple of questions I have for you regarding the fltk backend. When I plot using Helvetica for either the axis or text fonts, the screen display shows a oblique font. The printed/saved graph doesn't do this, nor does gnuplot. Do you know what that is about? Also, going from either gnuplot to fltk or, particularly, the reverse, after making plots does not work very well. Do you know a work around? |
