Hi there; I feel like I'm "nearly there" with porting this game to run with winelib, a version checked out from winehq CVS about a week ago. Because I wanted my build system to be cross-platform, and WINE only as a stop-gap, I'm using the Jam build system and so can't directly take advantage of winemaker. Plus I would rather learn and document how the build process works manually, since I can't find this information anywhere else. Anyhow I now have the 400-odd source files compiling happily against my wine header files once I'd excised the need for Direct3D. I have a directory full of object files with external references to Win32 functions and a WinMain function. So to do the final linking step I've used (based on watching the example winemine build process): $WINE/tools/winebuild/winebuild \ -fPIC -DSTRICT -D_REENTRANT \ -exe LSNClient.exe -mgui Builds/native-debug-linux/Source/*.o \ -L$WINE/dlls -luser32 -lgdi32 -ladvapi32 -lkernel32 -lddraw -ldsound \ -lwinmm -ldisplay -ldispdib >Source/LSNClient.exe.c and then compiled & linked LSNClient.exe.c to the rest of the object files with the -shared flag, which leaves me with a shared library. Sideline: am I correct in thinking that winebuild's job is to scan the supplied object files for Win32 dependencies and construct the necessary glue code to load the needed .dll.so files? What's the reason that the linking process can't correspond more closely to "normal" linking, i.e. where I could just supply -lddraw -lwine to my program to produce a final binary? I then run ../wine/wine LSNClient.exe to try to run the game, and get this error: err:module:BUILTIN32_LoadLibraryExA loaded .so but dll display.dll still not found - 16-bit dll or version conflict. err:module:PE_fixup_imports Module (file) display.dll (which is needed by Y:\Work\Nemesis\LSNClient.exe) not found Any idea what might be going wrong, or how I could diagnose it? More generally, the natively compiled .exe runs okay (if grindingly slowly, and with a couple of display glitches) under the binary loader, but I assumed that if I could produce a native version I'd be avoiding a lot of overhead and make my debugging job easier since I could use familiar GNU tools to debug my portability code as I wrote it. What efficiency gains will I make compiling a native "shared library exe" with gcc as opposed to just compiling with Visual C and running it under the normal WINE binary loader? I'm interested in how the latter works efficiently, so any advice in this direction would be appreciated-- I've thought on more than one occasion that maybe I should skip the WINE stop-gap and port it to SDL all at once, but the idea of being able to gradually wean the game off Win32 is appealing. cheers, -- Matthew Bloch Bytemark Computer Consulting Limited http://www.bytemark.co.uk/ tel. +44 (0) 8707 455026
