[Mingw-users] From VC++ to MinGW: unrealistic?

[Sylvain B. <syl...@li...>]

Hello,

I have a program here, that uses Visual C++ 6, MFC and DirectX 7.

My problem is that I want to 'port' it to GCC so that developers can
freely contribute to the development without requiring them to use an
expensive tool.
I myself only have the Introductory version of VC++,
which allows me to compile the program but do not permits its
distribution (a splash screen is automatically inserted in every .exe
so that I do not forget about that).
I plan to replace MFC with a cross-platform library such as wxWindows
or Gtk+ next.


So I first tried to replace the VC++ compiler with MinGW: I did a
makefile that uses all the includes and libraries directory of VC++,
just to see if I first can release a legally linked
application. Result: a 80+KB dump of syntax errors and ISO C++
non-compliance, and not any .o file compiled.


That afraid me! And I would like to know your point:
- Is it possible to compile Microsoft headers with MinGW? 
- Is my MinGW-porting task possible?
- If yes, how much of the code will I have to rewrite?


Thanks,
