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.

The commands I used were ...

sudo make clean
autoconf

./configure --enable-native-build --enable-shared --disable-static \
            --target=darwin --build=darwin --host=darwin \
            --enable-pic-flag --enable-64

It seems --enable-64 doesn't work right now. It won't work until I write a patch to generate code with 8 byte signed integer value.

sudo make octave

fgrep -in MXE_SYSTEM Makefile
11:MXE_SYSTEM := darwin

Iv'e attached the bzip2 log.

Ben, I don't find any reason why bzip2 doesn't compile on your system. I saw your logs and the only explanation I can give is that you might have forgotten to do "hg update" after doing "hg pull". Can you please check and let me know?
