Hi all,
I'm trying to write a DLL using GNAT 3.15p on Windows XP. The DLL needs to
export functions with the StdCall calling convention so that they can be
called from Visual Basic. Using samples/dll/ from the gwindows distribution
as a starting point, I haven't been successful in getting this to work.
If I just change the occurrences of pragma Export (C... to pragma Export
(StdCall..., the Ada test driver program call_gw_dll.adb fails to link because
the link library libgw_in_a_dll.a exports "_pop_a_window" only, while the
linker wants "pop_a_window@0". Neither of these is the "_pop_a_window@0" I
would have expected to see for a StdCall function.
Does anybody have a minimal set of code for a DLL, test program, and makefile
that demonstrates building a StdCall DLL using GNAT on Windows?
Best regards,
John
