Patch by me to fix crash described below. --ryan. To: sdl@libsdl.org From: Rainer Deyke <rainerd@eldwood.com> Date: Tue, 16 Aug 2005 01:08:18 -0600 Subject: [SDL] Bug report: SDL_CreateRGBSurface with SDL_HWSURFACE crashes If SDL is in full-screen mode with a hardware video surface on OS X, SDL_CreateRGBSurface with SDL_HWSURFACE crashes. The crash occurs on line 109 of SDL_Surface.c. This was tested on OS X 10.3.9 with both SDL 1.2.8 and the latest CVS. Here is a small C++ program that demonstrates the problem: #include "SDL.h" #include <stdio.h> namespace { void wait_for_key() { SDL_Event e; printf("%d\n", SDL_GetAppState()); while (SDL_WaitEvent(&e)) { if (e.type == SDL_KEYDOWN || e.type == SDL_QUIT) return; } } } int main(int, char *[]) { SDL_Init(SDL_INIT_VIDEO); SDL_Surface *screen = SDL_SetVideoMode(640, 480, 32, SDL_FULLSCREEN | SDL_HWSURFACE); SDL_Surface *s = SDL_CreateRGBSurface(SDL_HWSURFACE, 640, 480, 32, screen->format->Rmask, screen->format->Gmask, screen->format->Bmask, screen->format->Amask); wait_for_key(); if (s) SDL_FreeSurface(s); SDL_Quit(); printf("Success!\n"); return 0; }

The reason these libraries are built outside of the standard XFree86
tree is so that they can be linked as shared object code directly into
SDL without causing any symbol collisions with code in the application.

You can't link static library code into shared libraries on non-x86
Linux platforms.  Since these libraries haven't become standard yet,
we'll just include them directly.

These sources are synchronized with XFree86 4.2.1
