Porting an SDL_image program from Linux to Windows, Mac

SDL Development

Should be as simple as building it on those target platforms.

SDL rarely needs system specific code. If it does, it’s usually for endian-correction (so as long as you stay on x86 you’re good), and even then that isn’t necessary for your program.------------------------

has been very helpful with getting a mingw setup working with SDL and SDL_image on windows.

However, though the program does compile, it doesn’t run as it does on Linux. Instead of displaying the image, it displays a black screen (and prints no errors). I’m going to keep searching the documentation, but I’d still be interested in any hints.

I can’t see why. You sure test.png is in the proper folder?------------------------

Perhaps something happens that loses your rendering context? I’m not an
expert on this subject, but I do know from experience and from this list
that when I use SDL + opengl in windows, and I do something that changes the
rendering context (any call to SDL_SetVideoMode, basically), then the
context is lost. The resulting problems include that loaded textures are no
longer accessible, and must be reloaded.

Do you make calls to SDL_SetVideoMode after loading images? If so, you may
have to reload images.

Thanks,
