I'm trying to make a basic SDL program for my Slim.
This is the source:
main.c
| Code: | #include <stdio.h>
#include <stdlib.h>
#include <pspkernel.h>
#include <pspdebug.h>
#include <SDL/SDL.h>
/* Exit callback */
int exit_callback(int arg1, int arg2, void *common) {
sceKernelExitGame();
return 0;
}
/* Callback thread */
int CallbackThread(SceSize args, void *argp) {
int cbid;
cbid = sceKernelCreateCallback("Exit Callback", exit_callback, NULL);
sceKernelRegisterExitCallback(cbid);
sceKernelSleepThreadCB();
return 0;
}
/* Sets up the callback thread and returns its thread id */
int SetupCallbacks(void) {
int thid = 0;
thid = sceKernelCreateThread("update_thread", CallbackThread, 0x11, 0xFA0, 0, 0);
if(thid >= 0) {
sceKernelStartThread(thid, 0, 0);
}
return thid;
}
void Slock(SDL_Surface *screen)
{
if ( SDL_MUSTLOCK(screen) )
{
if ( SDL_LockSurface(screen) < 0 )
{
return;
}
}
}
void Sulock(SDL_Surface *screen)
{
if ( SDL_MUSTLOCK(screen) )
{
SDL_UnlockSurface(screen);
}
}
void DrawPixel(SDL_Surface *screen, int x, int y,
Uint8 R, Uint8 G, Uint8 B)
{
Uint32 color = SDL_MapRGB(screen->format, R, G, B);
switch (screen->format->BytesPerPixel)
{
case 1: // Assuming 8-bpp
{
Uint8 *bufp;
bufp = (Uint8 *)screen->pixels + y*screen->pitch + x;
*bufp = color;
}
break;
case 2: // Probably 15-bpp or 16-bpp
{
Uint16 *bufp;
bufp = (Uint16 *)screen->pixels + y*screen->pitch/2 + x;
*bufp = color;
}
break;
case 3: // Slow 24-bpp mode, usually not used
{
Uint8 *bufp;
bufp = (Uint8 *)screen->pixels + y*screen->pitch + x * 3;
if(SDL_BYTEORDER == SDL_LIL_ENDIAN)
{
bufp[0] = color;
bufp[1] = color >> 8;
bufp[2] = color >> 16;
} else {
bufp[2] = color;
bufp[1] = color >> 8;
bufp[0] = color >> 16;
}
}
break;
case 4: // Probably 32-bpp
{
Uint32 *bufp;
bufp = (Uint32 *)screen->pixels + y*screen->pitch/4 + x;
*bufp = color;
}
break;
}
}
void DrawScene(SDL_Surface *screen)
{
//Slock(screen);
int x,y;
x=0;
y=0;
for(x=0;x<480;x++)
{
for(y=0;y<272;y++)
{
DrawPixel(screen, x,y,y/2,y/2,x/3);
}
}
//Sulock(screen);
SDL_Flip(screen);
}
int main(int argc, char *argv[])
{
pspDebugScreenInit();
SetupCallbacks();
if ( SDL_Init(SDL_INIT_AUDIO|SDL_INIT_VIDEO) < 0 )
{
pspDebugScreenPrintf("Unable to init SDL: %s\n", SDL_GetError());
exit(1);
}
SDL_Surface *screen;
screen=SDL_SetVideoMode(480,272,0,SDL_HWSURFACE|SDL_DOUBLEBUF);
if ( screen == NULL )
{
pspDebugScreenPrintf("Unable to set 480x272 video: %s\n", SDL_GetError());
exit(1);
}
int done=0;
while(done == 0)
{
SDL_Event event;
while ( SDL_PollEvent(&event) )
{
if ( event.type == SDL_QUIT ) { done = 1; }
if ( event.type == SDL_KEYDOWN )
{
if ( event.key.keysym.sym == SDLK_ESCAPE ) { done = 1; }
}
}
DrawScene(screen);
}
SDL_Quit();
sceKernelSleepThread();
return 0;
}

and my makefile:
| Code: | TARGET = SDL_test
OBJS = main.o
CFLAGS = -O2 -G0 -Wall
CXXFLAGS = $(CFLAGS) -fno-exceptions -fno-rtti
ASFLAGS = $(CFLAGS)
LIBDIR =
LIBS = -lmad -lpspaudiolib -lpspaudio -lpsppower
LDFLAGS =
EXTRA_TARGETS = EBOOT.PBP
PSP_EBOOT_TITLE = SDL_test
PSPSDK=$(shell psp-config --pspsdk-path)
PSPBIN = $(PSPSDK)/../bin
CFLAGS += $(shell $(PSPBIN)/sdl-config --cflags)
LIBS += $(shell $(PSPBIN)/sdl-config --libs)
include $(PSPSDK)/lib/build.mak |
Compiling works
But when i put in into my GAME directory on my psp and try to start it, it gives an error: "The game could not be started" |
