RE: Cross compiling libffi for powerpc32?

["Amit Margalit" <amit dot margalit at siverge dot com>]

Hi,

Yes - I was finally able to compile it. Here is what I used:

./configure --prefix=/store/users/lab/Ltib-mpc8548cds-20071214/rootfs/usr/ --target=powerpc-linux-gnuspe --host=powerpc-linux-gnuspe --build=i686-pc-linux-gnu

Also, after the configure, something was wrong with the header files, so I had to manually make symbolic links of ffitarget.h and ffi.h to /usr/include on target rootfs.

And, the question I asked - whether powerpc32 is supported turned out to be answerable with a yes.

It's just that the documentation keeps referring to powerpc64, and fails to mention that the code for powerpc64 is actually 32/64 capable and I think it is selecting the correct mode in compile-time.
