So I can redo >the patch with the calls :) Typically you use MultiByteToWideChar() for any input strings and then WideCharToMultiByte() for possible output strings. You can look at shlwapi/path.c and other files in there to see how this is usually done. Depending on the place where you do it, it might be preferable to use dynamically allocated buffers instead of using stack space as Wine is already using quite a lot of stack. Principle: WCHAR *textW; INT countW = MultiByteToWideChar(CP_ACP, 0, textA, -1, NULL, 0); if((textW = HeapAlloc(GetProcessHeap(), 0, countW * sizeof(WCHAR)))) { MultiByteToWideChar(CP_ACP, 0, textA, -1, textW, countW); /* Do the Widechar call */ HeapFree(GetProcessHeap(), 0, textW); } Rolf Kalbermatter

Hi Dimi, Thanks for helping out. I made the changes you suggested to the gcc-mingw.mak file for STLPort. When I go make it does a: wineg++ -I../stlport -W -Wno-sign-compare -Wno-unused -Wno-uninitialized -mno-cygwin -O2 -D_STLP_USE_DYNAMIC_LIB dll_main.cpp -c -o ../lib/obj/MINGW32/ReleaseD/dll_main.o which throws up a world of errors, such as: In file included from ../stlport/cstdlib:25, from ../stlport/stl/debug/_debug.c:160, from ../stlport/stl/debug/_debug.h:418, from ../stlport/utility:40, from dll_main.cpp:35: /usr/include/c++/3.3.2/cstdlib:97: error: `div' not declared /usr/include/c++/3.3.2/cstdlib:102: error: `ldiv' not declared /usr/include/c++/3.3.2/cstdlib: In function `ldiv_t std::div(long int, long int)': I'm sure its something simple but I'm still not comfortable around gcc/winegcc. thanks, Scott. > -----Original Message----- > From: Dimitrie O.

Using winelib in python module
by Nikolay A. Liber 07 Sep '04

07 Sep '04

Hi All Have anybody tried to use winelib in python modules? I need to make python bindings to some propritary DLL that available as a binary only. I made shared library that simply dynamicaly loads that DLL using winelib mono hack. It works perfectly when I link it with simple C test program but crashes when I load in python module. Just a call to SharedWineInit() causes python to crash Program received signal SIGSEGV, Segmentation fault.

D3D7: textures, mipmaps, DDSCAPS_COMPLEX
by andrejoh＠c2i.net 06 Sep '04

06 Sep '04

Hi! First some good news (for me at least): Cedega from CVS can now be used to play Anarchy Online! [1] To get this working, Marius Grigoriu had to implement support for DDSCAPS_COMPLEX in the Cedega code; this support seems to be lacking in Wine. I've had a look at the patch, and both the Cedega and Wine implementations -- they are quite similar, but do have some differences in the texture creation part. In particular, Cedega has a lot of additional code in create_texture, and the parts in Wine's version seems to reside in the function create_mipmaps in the Cedega file (dlls/ddraw/ddraw/main.c). As far as I've understood things, the Cedega DDraw code is under the AFPL license, and cannot be merged with the Wine LPGL code; thus I've not looked further into that (the changes seems to be related to cube map support). However, the patch from Marius is released under the X11 license, and can be applied to Wine with minor tweaking (due to support for compressed textures in the Wine code). Should this be applied to the Wine tree (depending on me having ported it correctly, of course)? For reference, I've included the related part from the original patch as well (see also [1]). Unfortunately, even with this patch, running AO under Wine crashes with some texture related code: First chance exception: divide by zero in 32-bit code (0x419c6d5c).

Hacking in the AO code base (as in disabling certain textures), I've been able to get all the way into the client, but with almost no rendering. Any further help would be greatly appreciated!

Don't crash on failing DRIVER_FindFromHDrvr
by Uwe Bonnes 06 Sep '04

06 Sep '04

Hallo, I sent a patch to prevent wine from crashing last friday. It happend, when DRIVER_FindFromHDrvr returned NULL. No I found out, that I had sent that patch before last year. Eric answered > this doesn't seem right to me: either the loading fails and we shouldn't > get a valid handle, or it succeeds and we should be able to find it > there's must be something wrong elsewhere > could you please send a -debugmsg +driver,+module,+winmm to see what > happens ? and like before, I can't reproduce the error after reverting the patch: > the error no longer exists. I guess some registry entry was corrupt and a > successfull run corrected it later. > > However I see a lot of check after DRIVER_FindFromHDrvr() in other parts of > the code... If one dose "grep -3 DRIVER_FindFromHDrvr wine/dlls/winmm/*", every other usage of DRIVER_FindFromHDrvr is like if ((lpDrv = DRIVER_FindFromHDrvr(hDrvr)) != NULL) Why should expecting a NULL return be wrong? It happens, as the the crashes show.

Does changing the line 575 (in device.d, dlls/d3d8) to be if (ppBackBuffer) IDirect3DSurface8Impl_AddRef((LPDIRECT3DSURFACE8) *ppBackBuffer); make any difference - Looks like the app is doing an odd way to work out how many back buffers there are. Jason
