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;
}

This is the porting of 1.2.0 version of SDL (the latest stable one) to AmigaOS/68k. All the bugs known of the past version have been corrected. And I've added all the new SDL features. This version of SDL needs Cybergraphx V3 (r69+) or CyberGraphX V4 and AHI v3+. Probably it works also with P96 or CGXAga, but it's untested. This version is available as linked library for SAS/C and GCC, only 68k this time, a powerup (ppcemu compatible) and a morphos version will be ready quite soon (i hope). Implemented: - 8/16/24/32bit video modes, both fullscreen and windowed. - Hardware surfaces. - CGX blitting acceleration. - CGX colorkey blitting acceleration. - AHI audio (8/16 bit, with any audio format), always uses unit 0 for now. - Thread support (maybe not 100% compatible with other implementations) - Semaphores - Window resizing and backdrop windows (NEW) - Joystick/Joypad support. To do: - CDRom audio playing support - OpenGL (A guy was working on it but I've lost his tracks :( ) The SAS/C library is distributed with debug info attached, to strip debug info simply add STRIPDEBUG argument to the linker. NOTE: SDL includes debug output using kprintf, to disable it add to your project a function like this: void kprintf(char *a,...) { } Otherwise you can redirect the debug to a console window with sushi, sashimi or similar tools (the default output is the internal serial port). For info, support, bugfix and other feel free to mail me: Gabriele Greco (gabriele.greco@aruba.it) You can find also a small SDL Amiga page at: http://ggreco.interfree.it/sdl.html
