Re: Octave-Forge on OS X

[Per Persson]

I got (most of) the octave-forge stuff up and running, a quick scan 
tells me that the following stuff wasn't installed:

./extra/engine/NOINSTALL
./extra/fake-sparse/NOINSTALL
./extra/mex/NOINSTALL
./extra/patches/NOINSTALL
./extra/perl/NOINSTALL
./extra/tk_octave/NOINSTALL
./extra/ver20/NOINSTALL
./extra/Windows/NOINSTALL
./main/audio/NOINSTALL
./main/image/NOINSTALL
./main/linear-algebra/NOINSTALL
./main/plot/NOINSTALL
./main/sparse/NOINSTALL
./nonfree/gpc/NOINSTALL
./nonfree/splines/NOINSTALL

Some of those are disabled by default, some because they didn't compile 
on *first try* and some because I don't have XWindows installed on that 
machine.

It is a matter of working around the same bugs in Apples devtools as 
with octave itself. This should all be set correctly in mkoctfile 
**except** for the libstc++ bug that requires you to extract all the .o 
from libstdc++.a and link them explicitly.
I did some poking around and pinpointed libstdc++/cstrmain.o as the 
problem.

Try this: add an extra directory somewhere and inside that dir, do "ar 
-x /usr/lib/libstdc++.a". Then add that directory to "objfiles" in 
mkoctfile.

Follow the instructions for installing octave-forge. (I had to run "make 
install" in each of the subdirs to get install to work)

That should be it, but I'm writing from memory with the aid of some 
sketchy notes I took;-)

I'll attach part of my mkoctfile to serve as an example.

HTH,
Per

PS. If you do get it to work, let me know.
