using MFC with cygwin

using MFC with cygwin

[serj]

Hello,

I have unix console application. I want to use this application as a
back-end for windows GUI application. This GUI application is written
using MFC. I find out that there is no way to use cygwin *.o objects
and *.dll libraries in VC++ projects because of gcc and msvc compiler
uncompatibilities.

So i cannot use cygwin+gcc to compile my back-end and msvc to compile
GUI front-end. Am i right?

I cannot use msvc to compile entire project.

Can i compile MFC GUI application using cygwin+gcc? I tried to do it
but i have some problems:
Compiler cannot find MFC headers and some win32 headers like tchar.h.
I copy tchar.h to cygwin's win32 include directory and use gcc with
-I<path_to_mfc_headers> option.

But i still have problems:

/cygdrive/c/visualstudio/vc98/mfc/include/afx.h:621: variable or field `__fastca
ll' declared void
/cygdrive/c/visualstudio/vc98/mfc/include/afx.h:621: parse error before `('
/cygdrive/c/visualstudio/vc98/mfc/include/afx.h:1523: confused by earlier errors
, bailing out

So can i combine cygwin API functions with MFC?

I believe Metrowerks CodeWarrior for Windows comes with MFC.

http://www.metrowerks.com/

CodeWarrior is a much more standards-compliant compiler than VC++ and I think 
even more than g++, but it has a "compatibility mode" that allows it to compile 
a lot of broken VC++ code.

Maybe if you ported MFC, you could distribute a patch instead of your port.

Alternatively, maybe you could help me port ZooLib to Cygwin.  If you succeeded 
(or helped me to) the changes could be folded into the ZooLib distribution and 
everyone would benefit.  ZooLib is open source under the MIT license and is a 
lot nicer API than MFC.

http://zoolib.sourceforge.net/

some documentation can be had at http://www.goingware.com/zoolib/cookbook/

Best,

Hm, someone's been digging around in the email archives! ;-)
Actually, that's good to see.

While I won't argue the slight semantic differences pointed out
here between what I said and this response, I believe we both agree 
it makes the same point, at least in the context of Cygwin.  Anyone
that wants to can try to port MFC to any Win32-based compiler they
want but they will end up with something restricted by the Microsoft
license.

MFC was not ported to VC; it did not exist prior to VC.

I am 95% sure that (some) Borland compilers license (include) MFC. You might
be correct that it has not been ported, but Microsoft licenses it. The VC
compiler includes the MFC source code so it would not be too much work to
port (unlicensed). I assume that if source code existed that did the same
thing as MFC then it could be entirely legal.

I think the original question was about a console program that used MFC and
I would probably suggest not using MFC for that.

No one has ported MFC to any compiler besides VC++.  And while
it could be done, the benefits are minimal since the Microsoft
license would prevent you from distributing the result.

I'm not sure what problems you're refering to with regard to VC++
linking against Cygwin-made DLLs/LIBs.  This should be possible so
long as you take some care in not mixing C runtimes.
