Can't compile some SDL + OpenGL stuff ...

[gambiting]

Hi! I'm working on new game for NeoFlash Spring contest,and I can't compile my very early source :P.I guess I have all needed libs,so I don't know what's the problem.Also,the same source compiles to linux executable without problems.Errors I have are:

Please help.

[gambiting]

Ok,I repaired it - I removed glMultMatrixf from libriary source,and removed #include <iostream> from main.cpp - it wasn't needed.
But now I have much bigger problem - I want to run it through PSPLink,and all I get is:

Code: Select all

Also,I can see a cursor on a black screen,so I guess that at last SDL inits properly.When I start it from XMB it just hangs.Any ideas please?
I guess it's memory overflow,but this code at this stage ir VERY simple,and also I have build_prx=1 and PSP_HEAP_SIZE_MAX(); set.

[gambiting]

<double post,sorry>

[Insert_witty_name]

Try PSP_HEAP_SIZE_KB(20480) instead of PSP_HEAP_SIZE_MAX().

[gambiting]

Try PSP_HEAP_SIZE_KB(20480) instead of PSP_HEAP_SIZE_MAX().

Still the same error.

Well, you can either use the gdb for PSP in the sdk, or you can add prints to the screen (part of the debug code in the sdk). The print method is probably more popular, even on PCs. If you look through most programs, you'll find status prints all over. You'll find examples of using those debug prints in most PSP apps. It's pretty simple and works well enough for most devs.

Gdb debug gives:

I will try to figure out where it hangs with some debug output.I will write when I solve it.

[gambiting]

Ok,I figured out what's the problem,I made a debug statements like that:

Code: Select all

bool init_all()
{
	pspDebugScreenInit();
	
    //Initialize SDL
	if&#40; SDL_Init&#40;SDL_INIT_VIDEO&#41; < 0 &#41;
	&#123;
		return false;    
	&#125;
	printf&#40;"\t SDL_INIT Done!\n"&#41;;
    
	if&#40; SDL_SetVideoMode&#40; SCREEN_WIDTH, SCREEN_HEIGHT, SCREEN_BPP, SDL_OPENGL&#41; == NULL &#41;
	&#123;
		return false;
	&#125;
	printf&#40;"\t SDL_setVideoMode Done!\n"&#41;;
    
    //Initialize OpenGL
	if&#40; init_GL&#40;&#41; == false &#41;
	&#123;
		return false;    
	&#125;
	printf&#40;"\t initGL Done!\n"&#41;;
    

    
	return true;    
&#125;

And,inside init_GL function:

Code: Select all

bool init_GL()
{
    //Set clear color
	
	printf("\t initializing ....\n");
	glShadeModel(GL_SMOOTH);
	printf("\t shade model Done!\n");
	glClearColor(0.0f, 0.0f, 0.0f, 0.5f);
	printf("\t clear color Done!\n");
	glClearDepth(1.0f);
	printf("\t clear depth!\n");
	glEnable(GL_DEPTH_TEST);
	printf("\t gl_depth_test Done!\n");
	glDepthFunc(GL_LEQUAL);
	printf("\t depth func Done!\n");
	glMatrixMode( GL_PROJECTION );
	printf("\t matrix mode Done!\n");
	glLoadIdentity();
	printf("\t load identity Done!\n");
	gluPerspective(54.0f,(GLfloat)SCREEN_WIDTH/(GLfloat)SCREEN_HEIGHT,1.0f,1000.0f);
	printf("\t perspective Done!\n");
	glMatrixMode( GL_MODELVIEW );
	printf("\t model view2 Done!\n");
	glLoadIdentity();
	printf("\t load identity 2 Done!\n");
	SDL_GL_SetAttribute( SDL_GL_RED_SIZE, 8 );
	SDL_GL_SetAttribute( SDL_GL_GREEN_SIZE, 8 );
	SDL_GL_SetAttribute( SDL_GL_BLUE_SIZE, 8 );
	SDL_GL_SetAttribute( SDL_GL_ALPHA_SIZE, 8 );
	SDL_GL_SetAttribute( SDL_GL_DEPTH_SIZE, 16 );
	SDL_GL_SetAttribute( SDL_GL_DOUBLEBUFFER, 1 );
	printf("\t set atributes Done!\n");
	//glHint(GL_PERSPECTIVE_CORRECTION_HINT, GL_NICEST);
    
	if( glGetError() != GL_NO_ERROR )
	{
		return false;    
	}
    
	return true;
}

When I run it on PSP now,I can see:

Code: Select all

SDL_INIT Done!
SDL_setVideoMode Done!
initializing....

and then it hangs.So now I know that every simple OpenGl instruction will hang it - now the question is - why??? I thought that opengl is working fine on slim??

Ok,I found on the other thread that I have to recompile SDL with sdl support( -DHAVE_OPENGL cflag set),so I did.Now it won't compile with such errors:

[danzel]

Change the link order of your libraries, the LIBS line for DSP looks like:

LIBS= -lSDL_image -lSDL_mixer -lSDL -lGLU -lGL -lpng -ljpeg -lz -lm -lstdc++ -lc -lc -lpsputility -lpspdebug -lpspgu -lpspge -lpspdisplay -lpspctrl -lpspvfpu -lpspuser -lpsprtc -lpsppower -lpspdebug -lpspge -lpspaudio -lpspctrl -lpspnet -lpspnet_inet -lpspnet_apctl -lpspnet_resolver -lpsputility -lpspuser -lpsphprm -lpspsdk

DSP doesn't use freetype, slide that in around -lpng I think (assuming you are using it).

Hi

Thanks to gambiting i succeeded to compile my first application that uses SDL and OpenGL !
Actually i had to add the following libs to build correctly : -lpspirkeyb -lpspkernel -lpsppower
Does anybody else needed to add these libs to build a SDL/GL app ?

cheers

It all depends on what the game links to / requires. Im pretty sure a lot of the newer kernel games require these libs installed.
