Have you run into mine, too ? It's not particularly well done (it was my
first SCons tool), but I know it can work because I use it for my own Mex
extension, for which it has yet to fail.
The difference to your approach (and the one from the SCons Wiki) is that I wrapped
the SharedLibrary builder, as opposed to using the mex executable, following .
One thing I can mention if you try this route (be it with or without my tool):
you have to pass "-fno-reorder-blocks" to GCC starting with version 4.5,
otherwise MATLAB crashes (don't ask me why, maybe because of ABI
incompatibilities with its bundled libraries, but that's just a guess).
If you *did* try it and it failed for you for whatever reason and the above
doesn't help, I would definitely like to know!
