[C] [PRX] blit_string

[basfreak]

Hi,

Im trying to make a PRX but when i try it, i dont see the string i want to print.

this is my C code:

#include <pspkernel.h>
#include <string.h>
#include <stdlib.h>
#include "blit.h"

//#define printf(fmt, ...)
#define debug_log(fmt, ...)

PSP_MODULE_INFO("IRSMP3", 0x1000, 1, 1);


int main_thid;
int main_thread(SceSize args, void *argp)
{
    
    while(1)
    {
        sceKernelDelayThread(50000);


                        blit_string(60-17,265,"RAND",0xffffff,0x000000);

    }
}

int module_start(SceSize args, void *argp)
{

   	main_thid = sceKernelCreateThread("IRSMAIN_Thread", main_thread, /*8*/ 8, 0x04000, 0, NULL);
   	if(main_thid >= 0)
   	{
   		sceKernelStartThread(main_thid, args, argp);
   	}

	return 0;
}

//this isn't called
int module_stop(SceSize args, void *argp)
{
	return (0);
}

Makefile:

TARGET = irsmp3
OBJS = mp3.o blit.o exports.o

USE_KERNEL_LIBC = 1
USE_KERNEL_LIBS = 1
PRX_EXPORTS = exports.exp

INCDIR = 
CFLAGS = -DNOEXIT -DFPM_MIPS -O2 -G0 -Wall
#CFLAGS = -DNOEXIT -DFPM_MIPS -O2 -G0 -Wall -fno-builtin-printf
CXXFLAGS = $(CFLAGS) -fno-exceptions -fno-rtti
ASFLAGS = $(CFLAGS)

LIBDIR =
LIBS = -lpspkernel -lpsplibc

#EXTRA_TARGETS = EBOOT.PBP
#PSP_EBOOT_TITLE = SDK Test v1.0

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

exports.exp:

# Define the exports for the prx
PSP_BEGIN_EXPORTS

# These four lines are mandatory (although you can add other functions like module_stop)
# syslib is a psynonym for the single mandatory export.
PSP_EXPORT_START(syslib, 0, 0x8000)
PSP_EXPORT_FUNC(module_start)
PSP_EXPORT_FUNC(module_stop)
PSP_EXPORT_VAR(module_info)
PSP_EXPORT_END

PSP_EXPORT_START(irsmp3, 0, 0x4001)
PSP_EXPORT_END

PSP_END_EXPORTS

As you can see i've edited the original irsmp3.

Does anyone know why it doesn't work?

Bye,

I think this should be in Developer's Dungeon...

Bye,

The bolded ones are not needed.

You are trying to use LIBC and use the flag Kernel LIBC which is totally contrary.
Since you aren't exporting any funcs, these

PSP_EXPORT_START(irsmp3, 0, 0x4001)
PSP_EXPORT_END

aren't needed

USE_KERNEL_LIBC = 1 also delete?

[Maxy_PSP]

check VSHBlitter on PSP-Programming.com forums,

With VSHBlitter you can blit a string or image in the VSH(XMB)

No, that just means you should include pspdisplay.h in your blit.c file.

it doesnt work anyway

[adraveny]

The blit_string function use character unit not pixel unit to set the text position,you should try blit_string(((60-17) / 8) - ((60 - 17) % 8),(265 / 8) - (265 % 8),"RAND",0xffffff,0x0000 00);

Why did u bump the thread?
