[Wine] Debugging issues on MacOSX

[begemott]

Hello,

I have examined different possibilities to run a Windows program on Mac and it seems to me that Wine is the best one. 
Since the program I will try to run is complex I decided to test debugging capabilities of Wine.

What I did (tried)?

1. My system is: Mac Mini, Mac OS X 10.6.3.
2. I downloaded Wine 1.1.43 and built it successfully with:

Code:

export CFLAGS="-arch i386 -m32"
export CXXFLAGS="$CFLAGS"
export CPPFLAGS="-I/usr/X11/include"
export LDFLAGS="-L/usr/X11/lib"

./configure
make depend && make
(I didn't make install)




3. I created a very simple WTL based test application. It is a dialog with two buttons (OK, Cancel). Pressing OK purposely generates division 
by zero exception. Then I copied the .exe, .cpp, .h, .pdb files in a /test directory on my Mac.

4. I ran this application by ./wine /test/WTLTest.exe > ./error.log 2>&1
Then pressed OK and the program crashed. Here is a portion from the log:



Code:

use TrueType fonts please install a version of FreeType greater than

Now the questions:

1. Why there is no symbol information(line numbers etc.) for my executable? As far as I know Wine has its own implementation 
of imagehlp.dll that deals with debug symbols of PE executables. 
On the other hand I downloaded the demo of CrossOver Mac and it 
reported the source code information perfectly well.

2. Why there is no symbol information for the Wine modules? AFAIK the default Wine build includes symbol info by default and I have built Wine from source.

3. The annoying "Wine cannot find the FreeType font library.". 
Whatever I did I didn't succeed to install FreeType. But.. this is another story...

Does anyone have any idea how to deal with the debugging problems?

Regards.
