C/C++ Programming Help Thread

[Durka Durka Mahn]

Still gives me the same error.. :/

[Auraomega]

Well that way does work, I got it direct from NeHe's tutorials on GU, but yeah, your way does seem easier.

@spike021:
Nope, you need to do something along the lines of:

struct SceKernelLoadExecVSHParam param;
memset(&param, 0, sizeof(param));
param.size = sizeof(param);
param.unk5 = 0x10000;
param.vshmain_args = [insert args here];
param.vshmain_args_size = sizeof([args buffer]);

sceKernelExitVSHVSH(&param);

Or something to that extent.

Hmmm, thanks Aura, I'll give it a try later and see if I can work it, otherwise, I'll just use the in-game method.

[Durka Durka Mahn]

Nevermind I got it working now, thanks for the help guys.

For some odd reason the graphics.o file had to be deleted.

[Auraomega]

Hmmm, thanks Aura, I'll give it a try later and see if I can work it, otherwise, I'll just use the in-game method.

Seeing as you can't test it yourself, nor get the arguments yourself just yet, I'd probably go with the in game method for now, and use the "offical" method at a later date when your PSP is more homebrewable, I'd find the arguments for you myself but I'm on 3.52, and I know the arguments changed at 3.71 so its not much help.

Oh, and incase there was any confusion about getting the arguments, write an app and store it in flash0:/vsh/module/vshmain.prx, int main(SceSize args, void* argp) and simply write a file with the arguments in it to have a look at with a hex editor or something. You may need a few dumps to help find what varies and what doesn't. Oh, and don't forget to load the vshmain_real.prx file under vsh mode, normal module loading won't work.

Alright Aura, that will probably help a bit also. I actually do have someone that has been testing the homebrew files and such, but it should be fine. Thanks for the really quick replies too

[Judas]

Aura, maybe you could load the EBOOT from the RAM. Load the EBOOT into the RAM, then instead of passing the path to the EBOOT for argp, pass the pointer to the memory address of it.

[Xsjado7]

How is there any way to use the 'bigger than' and 'smaller than' operators in a switch statement?
For example:

int main()
{
int x;
int y;
x = 50;
y = 100;

switch(y-x)
{
	case (>10):
		//Code
		break;
	case (<10):
		//Code
		break;
}
return(0);
}

[yaustar]

Nope.

[Auraomega]

That failed too, as it doesn't load from a file it has no current working directory.

Back to the drawing board

help.c:54: error: expected '}' before 'COMPILE_TIME'

Please someone tell me where its missing

[Moose]

Shouldn't it be:

 "1+",     "1-compiled , COMPILE_TIME"

I'm probably wrong... but meh.

[eldiablov]

I doubt it, there is no problem with VERSION.

[Moose]

Oh, well then VERSION would be:

"1+\267", "1-Tile World: version , VERSION"

But yeah, I'm wrong

[Archaemic]

COMPILE_TIME is not being #defined.

[eldiablov]

you're right, the header wasn't included with the source. It's anybody's guess how i'm going to find it. But thanks Archaemic.

[Blackbelttcon]

hey i found a piece of code on the internet, and i think it will help download a string from the internet. i dont think the person posted the whole code though.

def download("www.google.com/logo.gif")
{
    def file = new FileOutputStream(address.tokenize("/")[-1])
    def out = new BufferedOutputStream(file)
    out << new URL(address).openStream()
    out.close()
}

if you no what this does, or how to use it, im having trouble compiling because of stupid errors.
thanks

[yaustar]

That isn't C++. I think it is Python or Ruby.

[Blackbelttcon]

o alright, thanks

[Archaemic]

No way that's Python...but it's definitely not C++. It looks vaguely like Java, but it's not.

[SG57]

It's in a language called 'Groovy', an agile dynamic language for the Java Platform.

[NameTaken33]

I just want to get something cleared up for myself. I understand that the PSP can run Lua, but apparently with this thread it can run C++ as well. I was just wondering if it is limited C++ (like ajax and the PSP browser) or can I code the full deal?

You have the full use of C++ language on the PSP.

[Auraomega]

Not strictly a PSP related programming question, but I respect you guys so I'd prefer asking here.

I'm planning on learning graphics on a PC tomorrow, but I'm not sure what to use - OpenGL or DirectX?

2nd question, which compiler/IDE would be best to use for whichever API.

3rd question, which is the best site to learn from?

I did try the NeHe stuff today, but I'm missing gLaux and I couldn't find it in the quick search I had, I'm just wondering if anyone knows of a compiler that comes with this?

Hope you guys don't mind these questions.

1.) I'd choose OpenGL, but me being an Apple guy my opinion may be biased ;). OpenGL is cross-platform though :)

2.) Depends. Visual Studio is a pretty "out-of-the-box" package. I've never used it for anything more than command-line apps though. Code::blocks is very nice also, and I know Yaustar is always recommending it.

3.) Nehe, http://videotutorialsrock.com/, and the free edition of "The Red Book", if you're learning OpenGL. No idea if you plan to use DirectX.

[michaelp]

Code::Blocks! A new version of it was released recently:
http://www.codeblocks.org/
-= Double Post =-

You have the full use of C++ language on the PSP.

What about the standard libraries? I know iostream wouldn't work, but what about <string> or <cmath> or <cstdlib> or <vector> etc.

[Bronx]

It's all there. I'm pretty sure iostream does work, but it doesn't actually print text to the screen. It prints it to textfile created for console output.

[Archaemic]

OpenGL, definitely. It's not bound to Windows.
And yeah, Code::Blocks.

[Anti-QuickJay]

How do I convert decimal to float?
I got float to decimal though.

What? floats hold decimal values. Do you mean double to float?
