Well, I guess this is a way of telling me that I didn't include enough info.
:)
I'm not intimating that this is a problem with Cygwin or the gcc (ld)
port per se, I'm just trying to find out if maybe there is a different way
that some libs export their methods. Or maybe there is a quirk I'm unaware
of. Let me reiterate that I have been able to link against other libs in
this same api using this same version of gcc on this same version of
Cygwin...so it's clear that it's possible.
Anyway, here is a listing of what happens during make when the error occurs.
Maybe this will be provide more insight:
gcc -v -mno-cygwin -L./lib -Wl,--add-stdcall-alias -shared -o cpic.dll
cpic.o -lwcpic32 -lwappc32 -wincsv32

Note that this is a DLL I'm trying to build, but I'm also unable to link
when just building an executable that uses this same lib. BTW, searching for
cminit AT 12 on wcpic32.lib does come back with results.
I hope this provides enough info.
TIA,
