Hi All,
First, thanks to all for the excellent work on Wine. I'm a Crossover Office user, and I anxiously await each week's Wine Weekly Newsletter as well to keep myself up with happenings in the Wine world. You guys truly rock.
But I digress. Here's the real reason for my e-mail:
I need to port one of my company's MFC-based application to Linux. My first thought was to use Winelib.
I understand from everything that I've read that I need to recompile MFC using Wine. Easier said than done, though. I've spent several hours just trying to get everything setup correctly, and things are still not compiling correctly.
First, some questions: - My initial attempt at compiling MFC was on the MFC source code from VS.NET 2003. After not being able to get a satisfactory Makefile configuration for compling that version of MFC, I figured that perhaps VS98's version of MFC was more commonly recompiled by Wine developers, so I'm currently trying to compile VC98's MFC. Is there a preferred version of MFC that I should be compiling, or are they all equally difficult? ;-) - I have the following RPM packages installed on my Mandrake 10.1 OS: libwine1-20040813-2mdk, winelib-0.3-1mdk, libwine1-devel-20040813-2mdk, wine-20040813-2mdk. I have also downloaded the latest wine source code from 20050111. As mentioned before, I also have Crossover Office installed. In your opinion, is there a more compatible or better set of libraries to use when compiling? Anybody compiled MFC using the Mandrake packages before? (FYI, wineg++ --version and winegcc --version both report that they are g++/gcc (GCC) 3.4.1. - Also, should I be using an older version of Wine's source code, instead of the very recent 20050111 version that I've currently got on my system?
I've read the Winelib documentation on compiling MFC and have combed through the mailing list archives as much as possible to get to where I'm currently at. After running winemaker on the VC98 source code directories and tweaking the resulting VC98/MFC/src/Makefile quite a bit, I also put the following #defines at the top of VC98/MFC/src/stdafx.h:
#define _AFX_PORTABLE #define _FORCENAMELESSUNION #define _AFX_NO_DAO_SUPPORT #define _AFX_NO_DHTML_SUPPORT #define _AFX_NO_OLEDB_SUPPORT #define _AFX_NO_RICHEDIT_SUPPORT #define _AFX_NO_ATL_SUPPORT
(That seems to be basically what the Winelib docs tell me to do.)
Anyway, here's the current output when I run 'make -f Makefile' in the VC98/MFC/src directory:

Funny how gcc is telling me to use -fpermissive, when I'm already using it. Anyway, that's probably a red herring.
If I can gain a clear understanding of the current steps needed to successfully compile MFC, I'd be more than happy to contribute updated 'Compiling MFC' docs to the Winelib docs to help out future developers that may be in a similar predicament as me.
Thanks in advance for any help you can give me.
