These are the first the first two lines causing problems
(note, if I comment a line out the very next one comes up,
for all the api it seems, even exotica works)
WINVER = link_c_func2(edx, "WINDOWS_VERSION",{NULL},C_UINT)
REPORT_MODE = link_c_proc2(edx, "REPORT_MODE", {C_POINTER,
C_INT})
All the C_ vars seem fine, and I've got limited knowledge on
linking Eu with C dll's so I can't see anything else.
Any help to fix this would be appreciated because as soon as
I can fix the exotica api I can release the library.
Cheers.
