But maybe someone else can reuse your scripts to make them work with MXE. I have come up with a temporary solution in Python and I have been able to produce a working application bundle of Octave for Mac OS X. I have committed all the scripts to my repo since it will be handy to have them all at one place.

Make sure you have created octave.app in the "dist" directory inside mxe-octave-anirudha. You can find information on how to use standalone.py is present inside the file.

I think I'm in need of a bit more detail.  I've cloned your repo.  Does your repo include all the mxe stuff and your changes?  I see a configure.ac and Makefile.in.  Do I start with autoconf -> configure -> make?  To build a Darwin app are there any specific options needed?

Oops! Sorry for missing that out. Do autoconf -> ./configure --enable-native-build --enable-shared --disable-static --target=darwin --build=darwin --host=darwin --enable-pic-flag --enable-64 -> sudo make octave
