Re: DOSBox 0.70 crashes on me

Posted on 2007-03-10, 21:11

I don't deny that I am a control freak when it comes to configuration management. I spend so much time at work, trying to maintain a build-environment that will allow us to re-create our applications and databases from scratch. I want consistency, repeatability, script-ability, and documentation of …

You need directx headers for directx to be compiled. Check the configure...you should see some lines - checking for ddraw.h... I have downloaded and extracted the latest DirectX SDK (dxsdk_feb2007.exe). I am a little unsure where to put them in my /mingw tree. From various comments I found, it …

SDL_dx5video.c: I can read the comments as well as anyone else. Is this a particular problem with DOSBox on some platforms, or is it just to prevent problems, should they happen? It was this diff: -#if 0 /* FIXME: enable this when SDL consistently reports lost surfaces */ +#if 1 /* FIXME: enable …

Okay - I think I understand the WM_SYSKEY issue now. The standard SDL-1.2.11 correctly passes these SYSKEY-events (e.g. ALT-key, F10, ..) to the Windows window-manager(?) so ordinary SDL/Windows applications will behave like they they always do and focus on the window-menu (with File, Edit, Help, …

A change to let DOSBox handle all keyinput? No, reverting a change. So with an unmodified SDL, the SDL-application would get control of the PrtScr/SysRq key on the keyboard? And with DOSBox, that is not desired? If so, why not keep SDL unchanged, accept the event in DOSBox, and pass it back to the …

here are my changes patch -p1 < sdl11rel.diff I look at those diffs, and here is my interpretation: SDL_video.c: Switch the order of the WINDIB and DDRAW drivers in the bootstrap-list, so DDRAW comes before WINDIB. But why? What do this accomplish? DDRAW is faster/better/more compatible across …

Aha! Thanks gulikoza: Looks like configure don't find ddraw.h: $ grep ddraw config.log configure:20: checking ddraw.h usability conftest.c:124:19: ddraw.h: No such file or directory | #include configure:65: checking ddraw.h presence conftest.c:90:19: ddraw.h: No such file or directory | #include …

Added a little debugging output to SDL_video.c:SDL_VideoInit(): for ( i=0; bootstrap[i]; ++i ) { fprintf( stderr, "JBA3: Checking for driver '%s' against bs[%i]('%s')\n", driver_name, i, bootstrap[i]->name ); if ( SDL_strncmp(bootstrap[i]->name, driver_name, SDL_strlen(bootstrap[i]->name)) == 0 ) { …

SDL_VIDEODRIVER=ddraw does not exist, that's why sdl crashes. directx and windib are the only available options. Why don't you compile in debug mode and check where it crashes? :) It dies (as expected) in sdlmain.cpp:main(), around line 1379: #if defined (WIN32) #if SDL_VERSION_ATLEAST(1, 2, 10) …

Ran all the SDL-test programs with SDL_VIDEOMODE=directx. No failures in the test-programs, but dosbox crashes. UPS!!! That was totally wrong. Noticed that it is not SDL_VIDEOMODE, it is SDL_VIDEODRIVER! Re-did the test with SDL_VIDEODRIVER=directx, and SDL_VIDEODRIVER=ddraw, and now the test- …

One maybe related issue... Trying to force windib with SDL_VIDEODRIVER and having output=ddraw will only show blank screen. It's funny cause output=surface works with windib. Log: SDL_Init: Starting up with SDL windib video driver. Try to update your video card and directx drivers! CONFIG:Loading …
