C/C++ Programming Help Thread

[SuperBatXS]

ehh i don't realy understand your question..
go to www.psp-programming.com maby your could learn something there

Lol. He's asking how to load or run eboots in C, you know, the programming language....

[Kwastie]

after I saw the link you gave to him I knew where he was talking about XD

is there a way to copy an int to another int ?!?
because i am working on a stopwatch and i want to store round info, someone any sugestion's

[Mr305]

the prx i am making works with no bugs on 3.10 OE but my 3.03 OE-C PSP will not boot when it is enabled. what must i do to laod my prx in 3.03 OE-C

#include <pspkernel.h>
#include <pspdebug.h>
#include <pspctrl.h>
#include <stdio.h>
#include <stdlib.h>


PSP_MODULE_INFO("XXXX", 0x1000, 1, 1);


#define XXXXX


 //Main function
XXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXX
                } 
                                sceKernelDelayThread(100000);
                                            }     
	return 0;
}

void* getModuleInfo(void)
{
	return (void *) &module_info;
}

It delays 1/10 of a sec... try 3,000,000. That should solve the problem[most common with prx's]

could someone upload that to sendspace or rapidshare plz
preferably sendspace
i get an error when downloading it

hey, would a C compilier work the same way as CYGWIN?
(as in, would it still make eboots in C?)

[yaustar]

Let's clear this up.

First up, you ARE programming in C.

All the compiler does is take C code and compile into a format for a targeted platform.

The PSP toolchain is a C and C++ compiler for the PSP platform.

Other C and C++ compilers exist for other platforms. Eg, PC, GP2X GBA etc.

Cygwin is nothing more then a Linux abstract bash shell for Windows.

[michaelp]

uh huh
so, can i use a C compiler for programming for the PSP?

[yaustar]

uh huh
so, can i use a C compiler for programming for the PSP?

Yes, but you can't just use any C or C++ compiler.

You have to use a C or C++ compiler that TARGETS the PSP platform

[michaelp]

alright, thanks
CYGWIN was a bit too hard to set up for me, so i tried looking for something else
do you know any that work for the PSP?

[yaustar]

DevKitPSP that comes with DevKitPro package. DevKitPSP is a precompiled PSP toolchain. It won't contain any external Libraries such PNG, SDL, MikMod etc. though.

[michaelp]

okay, i just download devkitpsp 10, i'll try installing it on my windows 98 computer and tell you what happens
thanx yaustar!

[SuperBatXS]

Lol, good luck on that...

[Moca]

First of all, on that code, your missing alot of { and your missing int main() {.

Maybe that is your problem?

If there were syntax errors, then it wouldn't compile in the first place. Therefore, he would not have a prx to run on the PSP. :|

I thought that was obvious.

[yaustar]

Lol, good luck on that...

Win98 will still work fine with DevKitPro.

[michaelp]

Lol, good luck on that...

are you mocking me? :Cry: :)

[Anti-QuickJay]

Lol, good luck on that...

Why does he need luck?

[youresam]

Why does he need luck?

If you had any common knowledge you would know.
Windows 98 = slow and buggy.

[SuperBatXS]

If you had any common knowledge you would know.
Windows 98 = slow and buggy.

Exactly. Why did i put the windows 98 in italics and bold then?

[Anti-QuickJay]

But it will STILL work fine.

[youresam]

But it will STILL work fine.

If he is lucky. Therefore: "good luck"
Calm down and think about it.

[Anti-QuickJay]

Ok, After much thinking, I realize it would be sorta buggy.

[SuperBatXS]

Wow. Did you just get windows 98?

[Anti-QuickJay]

No.

[SG57]

Maybe he cant get a better OSbecause his computer doesnt have enough RAM or up-to-date enough hardware? The laptop im currnetly on ran Windows 98 SE because i had 32 MB RAM. I went to a store, bought a 128 mb RAM. Now i may run up to Windows XP, but Windows 2000 is all i need, for Windows XP will run slower than 2000 on this.

Eww... Windows 2000

[SG57]

It gets the job done, and by far > than Windows XP, as there are far less viruses built for it (its been 3 years, no virus software and im running just as it was when i first booted up )

[michaelp]

well, it let me run the .exe, i just don't know how to run the actual program

what am i supposed to do after i run the devkitpsp10.exe file?

also, i have 2 xp comps, but the one i wanna learn on is a 98, that's the only reason why

[Mr305]

Is it better in terms of speed to use conditional operator as an arguement or use a seperate if statement for the actual statement?

[yaustar]

pos=0 ? 0xFF9EB7CD:0x42426F,

I am passing this as a argument to color, Will this work?
if Pos=0 use 1st color otherwise 2nd?

1. Use the standard if statement. There is VERY little point in using the conditional operator. There is no performence difference as they both still branch code.

2.

unsigned int colour = ( 0 == pos ) ? colour1 : colour2;

Hi, i have a weird problem. It has not much to do with the psp, rather with the C/C++ Compiler, Bloodshed Dev-cpp. Im starting to learn the C language.
When I got the compiler about a half a year ago, i tested it and everything worked perfectly fine. ( I was using Windows Xp at that time). I didnt continue to learn the language because I was kind of lazy .
But yesterday, i picked it up again and wanted to start over. So i downloaded the Dev-cpp compiler again ( I am now using Vista) and wanted to try out a simple Hello World script. But after it compiled it it gave me a weird error( I used a console app with C as lang.): "File: ...\...\Makefile.win"
"Message: [Build Error] exe: ***[Objects/MingW/main.c] Error 1".
Of course I didnt know wth was going on so I tried a little thing: I opened a new project with the same settings except, I openend as a C++ project and used the exact code as before.( which was btw:
#include <stdio.h>

int main()
{
printf("Hello World");
getchar();
return 0;
}

)
This time it was succesfully compiled and the command prompt opened and show me my "Hello World".
Now my question is, why isnt it working as a C project. Is it because of Vista?
I already tried the v5 of dev-cpp as well as wxDev-C++, same problem for both.
Hope some1 can help me out.
