Problem compiling Octave3

I'm trying to compile Octave3 from the AUR.
I'm getting an error buy I don't know why.
I'm pretty sure I've got all of the dependencies, but I'm getting this:

Re: Problem compiling Octave3

Thanks.  I'm not a programmer so I'm struggling to understand the problem.  Is it that mxarray.h needs to be patched?  If so, where do I find the patch?  Or do I simply need to insert '#include <cstring>' in the header of mxarray.h?

You need to just do that, but it's better doing it with a patch.
A tarball of PKGBUILD with the patch, and the package itself are available there :
http://shining.toofishes.net/pkg/

If you don't trust me, you should just use the PKGBUILD to be able to check things carefully
If you do, you can use the package directly to save the compile time.

Re: Problem compiling Octave3

I've noticed that if I invoke /usr/bin/octave-3.0.0 as root then everything works fine, but if I invoke it as an unprivileged user I get an error "warning: addpath: /usr/lib/octave-devel/octave/3.0.0/oct/i686-pc-linux-gnu: No such file or directory" AND the 'time()' function won't work or any of the time-related functions eg. "error: `time' undefined near line 1 column 1".

I'm going to try compiling the source code again, but I would be interested to know if it's a bug in the package or something wrong with my Arch install.

It works here... I compiled it with a PKGBUILD based on the comments on AUR.

Re: Problem compiling Octave3

Yeah, I've just compile the source code and I'm getting the same errors.  It seems that when I'm root, octave looks for

/usr/lib/octave3/octave/3.0.0/oct/i686-pc-linux-gnu

but when I'm a non-privileged user it's looking for

/usr/lib/octave-devel/octave/3.0.0/oct/i686-pc-linux-gnu

I removed octave-devel before installing octave3 but, obviously, I didn't do it correctly.  Can anyone tell me how to fix this above problem?
