 |
|
Hi all.
I have a trouble with pspgl on my psp. I tried to convert my program from sdl to sdl+pspgl. So, when my program reachs first gl function ( glMatrixMode(GL_PROJECTION) ), psp hangs up.
my example code:
| Code: |
#include <stdlib.h>
#include <stdio.h>
#include <unistd.h>
#include <signal.h>
#include <SDL/SDL.h>
#include <SDL/SDL_ttf.h>

/*
#include <GL/gl.h>
#include <GL/glu.h>
*/

#include <pspkernel.h>

#include <pspthreadman.h>
#include <pspdisplay.h>
#include <pspnet_inet.h>
#include <pspnet.h>
#include <psputility.h>
PSP_MAIN_THREAD_ATTR(THREAD_ATTR_USER);
#define printf pspDebugScreenPrintf
/*

I had to make a lot of changes to compile this, so I don't know if this is the solution for you, but it doesn't worked until I add PSP_HEAP_SIZE_KB(-1024);
I think I'm using a newer SDK than yours, in the main.c changes aren't a lot, but the makefile is completely different:

I have the latest sdk from the svn. I've updated my firmware to 5.00M33-6 and compile your code. So, psp hangs up the same way as with my code.

| Looks like the pspgl context wasn't initialized. As far as I know SDL should do that setup if it was built properly. Are you sure it was built with pspgl support? The output of "nm /usr/local/pspdev/psp/lib/libSDL.a | grep GL" should show if it was. Also, try compiling other SDL OpenGL PSP apps that you know work, that will let you know your build system is OK. |

I have not such application yet :-). So, I searched this and other forums, I found several similar unresolved problems with running SDL + pspgl programs. Looks like a bug in pspgl or sdl psp port.
Thank for the reply! |

Thanks!
I tried to configure with --enable-video-psp option and this functions had appeared in the lib.
But this option is documented neither in the README.PSP nor in the ./configure --help output. |

| Post the output of the configure script here. It will tell you if it found PSPGL. |

Sorry. Everything fine. There is no option --enable-video-psp :-). I have understood why my SDL was without PSPGL functions. First, my pspsdk was built without pspgl. After I built pspgl, I configured sdl and called make without make clean. Stupid error.
Thank you for the help! |
