[Mingw-users] dlltool/g++ problem solution

[Johannes B. <zyn...@gm...>]

Hi everyone,
Thanks for the many answers, I finally managed to get it right.
Ornamenting the .def like a Christmas-Tree didn't help, but I found
the following solution:

def-file:
LIBRARY mydll.dll
EXPORTS
       function1 @ 1 NONAME
       function2 @ 2 NONAME
       ...

dlltool --input-def mydll.def --output-lib mydll.lib
       
function-declarations:
__declspec(dllimport) __stdcall function1(int a, long b);
__declspec(dllimport) __stdcall function1(char *a, long b, bool c);
...

Thanks for the info Lloyd!
When I found out I needed __declspec(dllimport) I looked into the
attribute-list and saw the following:

dllimport: On the PowerPC running Windows NT, the dllimport attribute causes
the compiler to call the function via a global pointer to the function
pointer that is set up by the Windows NT dll library. The pointer name
is formed by combining __imp_ and the function name.

If you know what dllimport is doing you can actually understand this
passage! ("puzzles are always easy when you know the answer")
But why only PowerPC on NT? Oh well...


Thanks for the help everyone,
Johannes Blume
