makefile

TARGET = hello
OBJS = main.cpp

CFLAGS = -O2 -G0 -Wall
CXXFLAGS = $(CFLAGS) -fno-exceptions -fno-rtti
ASFLAGS = $(CFLAGS)

EXTRA_TARGETS = EBOOT.PBP
PSP_EBOOT_TITLE = Hello World Test

PSPSDK=$(shell psp-config --pspsdk-path)
include $(PSPSDK)/lib/build.mak

OBJS = main.cpp

Should be:

OBJS = main.o

[MrChaos]

OBJS = main.cpp

Should be:

OBJS = main.o

Lol! I feel stupid. Thanks.

One time I had to change it to main.cpp, now I gotta change it back to main.o..hehe.

Thanks again.

I'm having trouble installing libtools under Cygwin. It seems like one file cannot be compiled. Here are the last messages before the activity stopped.

hey guys, im plannin to reformat my laptop but my cygwin is on the C drive.. so im burnin my whole cygwin folder into a dvd... will it work? im on a low dsl connection and itll be a pain if i reinstall cygwin again

nope, not working what will i do to make my cygwin on dvd work? please help ...

[hallo007]

just back it up on dvd and recopy it after formatting
-= Double Post =-

string fileList[222];
void getFileList(const char *path)
{
	SceUID bufferFile;
	char nextPath[256];
	int z = 0;

	bufferFile = sceIoDopen(path);
	if(bufferFile > 0)
	{                  
		SceIoDirent dir;
                memset(&dir, 0, sizeof(SceIoDirent)); 
		while(sceIoDread(bufferFile, &dir) > 0)
		{
                    strcat(fileList[z].c_str() , path);  
                    z++;
                    if(z > 222 ) break;
		}
		sceIoDclose(bufferFile);
	}
}

I know this fucnton will be slow , how can i speed it up?(make it faster)

hallo - Does the term 'registry' mean anything to you? You can burn your whole cygwin folder to a dvd (even though itll fit on a CD-R at ~500 mb) but after you recopy it back, youll need to make some registry additions. To do this, you could go into your registry and find the Cygnus registry folders and copy them to that DVD as well. Then once you've reformatted, enter the Cygnus registry folders back into the registry where they were before you formatted.

[hallo007]

no never heared about it

[MaTiAz]

no never heared about it

System registry is one of the basic fundamentals of a Windows system... -_-

easier way:

1. copy cygwin to the formatted harddrive.
2. download and install cygwin again to restore the registry keys.
3. DONT install the toolchain. That has already been done with the copy.

Installing cygwin shouldnt even take that long. maybe 1 hour. Unless you dont want to wait that long, then good luck with another method.

I'm looking for a tutorial on installing the Compiler and everything on Linux... I don't want to screw up GCC and everything because I'm using Gentoo... (In which everything is built and doesn't use packages)

Has anyone figured out my Libtools installation problem? Hallo007 said it could be a missing lib but I don't know which one it could be.

I'm installing a new version of Libtools because I wanted to setup FreeType2. When I run the first shell script for that, the "libtoolize" command is not found. But now I'm also having problems installing Libtools too! (the message text is in my previous post)

[hallo007]

the psp doenst see a different between image.png and IMAGE.PNG does it?

[Kwastie]

well the psp does see differents bitween IMAGE and image :S realy stupid

[hallo007]

windows doenst, are u sure?

[PSPJunkie_]

windows doenst, are u sure?

I wouldn't think so.

[IchigoKurosaki]

I'm pretty sure the PSP is Case Sensitive... Much like a UNIX/Linux Operating System...

[hallo007]

thnx

[Moca]

No it doesn't.

No, the PSP is not case sensitive when dealing with folders and files.

[HippyG]

I'm planning on learning c. Can someone pm a good link on where to start? I downloaded Dev-C++. It all looks a little much for me. I would just like a simple tutorial that takes me slowly. BTW, I know a little LUA.

[PSPJunkie_]

[LINK]
Read that. ^^

[HippyG]

Thank you:)
My aswell not post again,
Thanks to the poster below me too.

[LMelior]

If you're looking for some very basic tutorials, there are several here:
http://www.cprogramming.com/tutorial.html#ctutorial

They aren't exactly comprehensive, but they will at least introduce you to the concepts. If you only know a little Lua, that probably just means you've learned some syntax, which won't help you much. You'll need a book to get more depth, and if you have the means a hard copy would be preferable to an online copy, just to save your eyes and your Alt and Tab keys. If you'd rather not spend any money, there are plenty of ebooks floating around that you'll find with a minimal amount of Googling.

why cant i include this in two sources

#ifndef _VARIABELS_H_
#define _VARIABELS_H_

#include <string>

string fileList[222];

#endif

i get multiple defenition error:s

Check your other files' headers.

You have an error in that code to start off with:

#ifndef _VARIABELS_H_
#define _VARIABELS_H_

#include <string>

std::string fileList[222];

#endif

[hallo007]

nono , i used using namespace std; at the beginning of the source;-)
there arent any other errors;)

[yaustar]

If you are dealing with shared global variables (ick), this is how you should do it:
variabels.h

#ifndef _VARIABELS_H_
#define _VARIABELS_H_

#include <string>

extern std::string fileList[222];

#endif

variabels.cpp

#include <string>
std::string fileList[222];

We need to source to other files if you are still getting redefinition errors.
