you have to create your own trace function i believe as i haven't seen any function on the psp that does this, although it's fairly simple just create a function that well write text to a file

yeh but what text...?

[yaustar]

printf usually outputs to TTY over PSPLink. This is why I keep saying that printf should NOT be #defined to something else.

[JaSo PsP]

yaustar: why does the program on the previous page make my PSP freeze when ran?

No idea. Wild guess (depending on the size of the struct) stack overflow?

    SceIoDirent directoryEntry[MAX_DIRS];

Reduce the number and see if it still runs?

As Archaemic said, add traces to your code to PSPLink and narrow down the line that is causing the crash.

int IdDump(const char* dst)
{

    char PrintBin[56] , dump[512];
	int BinSave;
	u16 idkey;

	BinSave = sceIoOpen(dst, PSP_O_CREAT | PSP_O_TRUNC | PSP_O_WRONLY, 0777);
	
	if(BinSave<0) { return 0; }
	pspDebugScreenClear();
	
    
	for(idkey=0x000;idkey<=0x200;idkey++) // Ampliado desde 0x000 hasta 0x200 (anterior 0x004-0x127)
	{
		pspDebugScreenPrintf("key 0x%03X\n",idkey);
		sprintf(PrintBin,"KEY : 0x%03X\n",idkey);
		sceIoWrite(BinSave, PrintBin, 512);
		sceIdStorageReadLeaf(idkey, dump);
		sceIoWrite(BinSave, dump, 512);
                }
	
	
	sceIoClose(BinSave);
        return 0;
}

sceIdStorageReadLeaf(idke y, dump);

it crashes at getting the first key:s

I am on the verge of crying. 8 hours for the toolchain. now sdl refuses to install. please tell me what's wrong somebody.

[email protected] ~/sdl
$ make

Also when running ./autogen.sh i get this:

Now you are ready to run ./configure

This may be relevant to the problem

[Archaemic]

Did you run the ./configure script? If so, with which parameters?

[eldiablov]

LDFLAGS="-L$(psp-config --pspsdk-path)/lib -lc -lpspuser" \
./configure --host psp --prefix=$(psp-config --psp-prefix)

[Archaemic]

What's the full path to the SDL folder?

[eldiablov]

D:\cygwin\home\Server2003 \SDL

It may be something to do with automake. How do i force it to use automake 1.9 ? instead of 1.10 ?

[JaSo PsP]

i think i found my problem, i was supposed to add 'memset' to the code... Me thinks...

WANT_AUTOMAKE="1.9" before you type make.

I remember what was in your sig

[eldiablov]

erm. About popups ?

Cant you help me with my SDL problem ?

[Mr305]

I would never recommend nor TRY SDL myself. But why would u need it?

BTW , your Sig was: "I drink a lot. I'm immature. I love myself. Sue me" Put it back.

[eldiablov]

no. I refuse . I want to port something which requires SDL. I normally wouldnt touch it with a barge pole.

[hallo007]

how do you get the "main thread's stack size"????

[vodkkaa]

how do you make a simple printf clock hh:mm:ss.

[Anti-QuickJay]

void CurrentTime( char * timeText) {
      pspTime rtime;
      sceRtcGetCurrentClockLocalTime(&rtime);
      snprintf(timeText, 8, "%i:%02i" , rtime.hour , rtime.minutes);
}

Fanjita's code in the Post your C examples Thread

[vodkkaa]

^^ thank you

edit: what include do i need for the function sceRtcGetCurruentClockLoc alTime

[Archaemic]

psprtc.h

[vodkkaa]

why wont this work. all it writes is a ' and thats it

void CurrentTime( char * timeText) {
           pspTime rtime;
           sceRtcGetCurrentClockLocalTime(&rtime);
          snprintf( timeText, 8, "%i:%02i" , rtime.hour , rtime.minutes);        
   
}

 int main()
 {
    dsxSystemInit();
		
	while(1)
	{                       
           dsxDrawingStart();
      	   dsxDrawFontDefault(0, 100, GU_RGBA(0, 0, 0, 255), CurrentTime);
             
           

     
           dsxDrawingEnd();    	
	       }

	return 0;
}

and makefile:

# Target Name
TARGET = battery

# Source Files
OBJS = ./main.o

#Build as a prx
BUILD_PRX = 1

# Libraries
LIBS = -ldsx -lpspgum -lpspgu -lm -lpsppower -lpsprtc -lpsphprm

# Misc.
INCDIR = 
CFLAGS = -O2 -G0 -Wall
CXXFLAGS = $(CFLAGS) -fno-exceptions -fno-rtti
ASFLAGS = $(CFLAGS)

LIBDIR =

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

[Archaemic]

I'm surprised that that would even COMPILE.

void CurrentTime( char * timeText) {
           pspTime rtime;
           sceRtcGetCurrentClockLocalTime(&rtime);
          snprintf( timeText, 8, "%i:%02i" , rtime.hour , rtime.minutes);        
   
}

 int main()
 {
    dsxSystemInit();
	char *time = malloc(sizeof(char)*9);
	while(1)
	{
           CurrentTime(time);
           dsxDrawingStart();
      	   dsxDrawFontDefault(0, 100, GU_RGBA(0, 0, 0, 255), time);
             
           

     
           dsxDrawingEnd();    	
	       }

	return 0;
}

[JaSo PsP]

Well, the 'CurrentTime' doesnt return anything, void CurrentTime( char * timeText). When you put it in the drawfont function, it doesnt know what to write because that function returns void... The function may work better like this:

char* CurrentTime() {
           pspTime rtime;
           char* timeText;
           sceRtcGetCurrentClockLocalTime(&rtime);
           snprintf( timeText, 8, "%i:%02i" , rtime.hour , rtime.minutes);
           return timeText;
}

plus, when you used the function, you didnt put brackets after it '( char* timeText )' You were supposed to full it with what you wanted to fill...

[Archaemic]

JaSo, that will cause nothing but trouble. You need to initialize timeText with some memory first.

that must be why i always get freezage when i use pointers with sprintf.... thanx :) ill use malloc more often.

[vodkkaa]

void CurrentTime( char * timeText) {
           pspTime rtime;
           sceRtcGetCurrentClockLocalTime(&rtime);
          snprintf( timeText, 8, "%i:%02i" , rtime.hour , rtime.minutes);        
   
}

 int main()
 {
    dsxSystemInit();
	char *time = malloc(sizeof(char)*9);
	while(1)
	{
           CurrentTime(time);
           dsxDrawingStart();
      	   dsxDrawFontDefault(0, 100, GU_RGBA(0, 0, 0, 255), time);
             
           

     
           dsxDrawingEnd();    	
	       }

	return 0;
}

this code returns the same results as the code i was using. just a ' on screen

[Archaemic]

Try changing
dsxDrawFontDefault(0, 100, GU_RGBA(0, 0, 0, 255), time);
to
dsxDrawFontDefault(0, 100, GU_RGBA(255, 255, 255, 255), time);

[vodkkaa]

dsxDrawFontDefault(0, 100, GU_RGBA(0, 0, 0, 255), time);
to
dsxDrawFontDefault(0, 100, GU_RGBA(255, 255, 255, 255), time);

im getting a warning from cygwin saying "passing arguement 4 of dsxDrawFontDefault from incompatible pointer type"

[Archaemic]

Then you don't have the code exactly as I have it.

Well, here's a better way anyway:

int main() {
    dsxSystemInit();
    pspTime time;
    for(;;) {
        dsxDrawingStart();
        sceRtcGetCurrentClockLocalTime(&time);
        dsxDrawFontDefault(0, 100, GU_RGBA(0, 0, 0, 255), "%i:%02i",time.hour,time.minutes);
        dsxDrawingEnd();
    }
    return 0;
}

If that still doesn't work, then it's because I know nothing about DSX.

it works!! thank you so so much
