[Buildroot] including python when compiling for microblaze

[Johannes Teiwes]

I am currently trying to port the python package in buidroot to the microblaze platform.
I have everything set up with a custom toolchain etc. and it works fine. The problem is
the libffi library, which is required for building any script language (e.g. perl, python)
for buildroot. The exact error message says

configure: error: "libffi has not been ported to microblaze-unknown-linux-gnu."

Has anyone started to port libffi to another platform or even found a specific workaround
for microblaze? Is there any alternative to the libffi library or installing python via buildroot?

Any help is greatly appreciated.

Apparently, libffi has no supported for microblaze, and it seems that
libffi is a mandatory dependency for building Python. It looks like you
have two options:

 *) Port libffi to Microblaze

 *) Use a more lightweight scripting language such as Lua. Python is
    quite heavy for MMU-less systems at 100-180 Mhz such as Microblaze
    systems. Lua is probably a much better fit for this kind of systems.
