PSPGL - Compiled lib ok, demos not so much[Solved]

Post by Kojima »

I succesfully downloaded and maked the library without any problems, but when making the demos I get the following error,

Code: Select all

C:\pspdev\pspgl\tests>make
mkdir .deps
convert firefox.png rgba:firefox.raw
Invalid Parameter - rgba:firefox.raw
make: *** [firefox.raw] Error 4
I removed the rule that invokes convert and then I was greeted with,

Code: Select all

C:\pspdev\pspgl\tests>make
make: *** No rule to make target `firefox.o', needed by `bezier.elf'.  Stop.
Which I assume is because convert never run, but I don't know really. Anyone else run into these problems? ( I can compile pspsdk demos fine )

Thanks, I'll have another stab at Cyngwin.
-edit- Do you know how to manually download the package you mentioned in that thread?
(Sorry for the dumb questions, but I've never used cyngwin before other than for about 20 mins a year or so back)

Does anyone know of a reason why cygwin would omit most of it's dev tools btw? I recall it taking an hour or so to install before, but now it takes under 10 mins and doesn't install vital tools like cc1.

Got it working by directly linking to the imageshack convert, but now there's a bunch of new errors,

Code: Select all

C:\pspdev\pspgl\tests>make
C:\convert firefox.png rgba:firefox.raw

considering it was only one file, I removed it and remaked, this time I get,

Code: Select all


C:\pspdev\pspgl\tests>make
make: *** No rule to make target `depthtest.elf', needed by `all'.  Stop.
Any ideas?

Got it compiled ago in the end.

For anyone else running into trouble with it, it's because you need zlib and libpng installed before hand.
I couldn't get libpng installed(Wouldn't compile out of the box, and I didn't feel like trying to fix it) so I just removed the screenshot code from the demos and voila, it all worked.

I guess you're not using the libpng and zlib from svn.ps2dev.org. They both work.

It is sometimes hard to know which library needs which other library, and in what order you need to install them. For instance libpng needs zlib installed first, and i think also another library.

I did grab them both from the svn, but libpng wouldn't compile.
zlib compiled fine first time.

In fact, libpng is the only lib I ever downloaded from ps2dev's svn that hasn't worked, so I guess it's just as arwin says a missing library, but I wasn't in the mood to figure out which one.

Did you bother to read the libpng README.PSP file? From the readme:
Requirements:

zlib

No I didn't.

Got another problem now, everything generally is working, but there's one function that can't be linked for some reason.

undefined reference to `gluOrtho2D'

I'm linking to lglu so I don't think it's that. Any ideas?

From looking at the pspgl source, gluOrtho2D doesn't appear to be implemented. Use glOrtho() instead. Here's my method for setting up 2D space for the gui:

Code: Select all

void pspRenderer::setup2D()
{
	GLCHK(glViewport( 0, 0, 480, 272 ));
	GLCHK(glMatrixMode( GL_PROJECTION ));
	GLCHK(glLoadIdentity());
	
	GLCHK(glOrtho(0.0, 480.0, 0.0, 272.0, -2.0, 2.0 ));
	GLCHK(glMatrixMode( GL_MODELVIEW ));
	GLCHK(glLoadIdentity());
}

Thanks Z, I'll give it a go. Glad it's possible, really want to lock down the 2d parts of my engine 'fore going 3d.

-edit- fixed it, was just a rouge function call that was screwing up the projection matrix.
