I’ve successfully built SDL from source using bcc 5.5.1 but any SDL test
application using it crashes right away at startup. I’m looking for some
help and/or guidance on how to resolve this issue.
Just to fill in some info, SDL-1.2.14 was used. The project’s compiled as
a dll with multithreading enabled and linked to C runtime dynamically.
I’ve also rebuilt it with debugging info. When I step through with a
debugger up to the point of crash it seems to be coming from
redirect_stdout in the sdlmain. If I remove sdlmain.lib and use the
source file sdl_win32_main.c directly in the SDL test project then that
doesn’t crash anymore. Instead it just crashes later on at SDL_Init
routine.
I’ve already checked the calling conventions used and they all seem to
match up – everything is using cdecl. I’ve also checked and made sure
the compiled sdl.dll and the test application was using the same dynamic
C runtime instead of statically linked.
The SDL wiki under Borland section mentions to use the -b to make sure
enum’s are same size as int but that option is enabled by the compiler by
default unless explicitly turned off. I did rebuild SDL with that
compiler/linker switch just to be sure though.
When it crashes, it’s always a access violation in trying to write to
some address(c000005). Like for example during a typical SDL init attempt
like this:
// initialize SDL video
if ( SDL_Init( SDL_INIT_VIDEO ) < 0 )
{
printf( “Unable to init SDL: %s\n”, SDL_GetError() );
return 1;
}
After the call into SDL_Init(), control doesn’t flow back into the test
application. Instead it crashes somewhere bizarre like somewhere in
ntdll.dll with something having to do with NTDLL.RtlEnterCriticalSection.
When I inspect the stack trace at that point I usually get something like
this:
:77982269
:0044A04C
:0043F02B
:0043F7C4
:0043EF25

SDL_CreateSemaphore(1)
SDL_CreateMutex()
SDL_CreateSemaphore(1)
SDL_CreateMutex()
SDL_CreateSemaphore(1)
//and it keeps repeating… seems stuck in infinite mutual recursion…
//is this normal?
I’m not sure what else to try at this point as I’m pretty stumped. If
anyone have any suggestions or need me to provide more info please feel
free to add it to the comments.
Thanks
