in Modules/_ctypes/ctypes.h:

typedef struct {
[..]
        ffi_type *atypes[0];
} ffi_info;

AFAIK, arrays must be of size > 0.
_Most_ compilers accepts this, but not all
(especially my HP-UX compiler).

Please change *atypes[0] to *atypes[1]!

Bye,
Johannes

Thomas, could you take a look?

[theller]

I can, and probably will, change this in Modules/_ctypes/ctypes.h. However, I'm afraid it will not help the OP too much because it seems he cannot sucessfully compile the libffi sources with this HP-UX compiler anyway because of at least *some* other problems.

I have the impression that libffi is GCC-specific, and unless someone provides a complete patch for the HP-UX (or other) compilers it will probably stay this way.

Fixed in release25-maint branch (SVN rev. 56354) and trunk (SVN rev. 56355).
