[Mingw-users] Exporting classes to MS Visual C++

[Marcello P. <te...@at...>]

Hi Mingw team,
I was trying to compile Blitz++ but as you know Microsoft is not able to
do a decently updated compiler.
Unfortunately I know well MFC, and for many other reasons I cannot
switch completely to an other compiler.

So I though to make a DLL with Mingw and then create a library from it
using
the two Microsoft utilities together:
DUMPBIN /EXPORTS <.DLL file name>    (or, better,   dllwrap ...
--output-def )
LIB /DEF:namedll.def /MACHINE:IX86

Everything is working perfectly with C functions, but not with C++
classes.
There are two problems:
1) it is hard to decipher the name mangling of Microsoft's compiler
(especially for overloaded functions)
2) I need to export the virtual table
It seems possible to export/import the virtual table but  I'm wondering
if the virtual table would be managed by the gnu compiler in way
compatible with the MS Visual C++ compiler.

What do you think ?
Do I have to give up ?
