Hi, this is my makefile:

TARGET = platform
OBJS = intraFont.o libccc.o font.o common.o parser.o dialogs.o graphic.o libmsn/msntest/custompoll.o exceptionHandler\utility\exception.o main.o

BUILD_PRX=1

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

LIBS= -g -lpng -lz -lpspwlan -lpspnet -lpsphttp -lpsputility -lpspgum -lpspgu -lmsn_d -lssl_d -lcrypto_d -lm -lstdc++

LIBDIR =

EXTRA_TARGETS = EBOOT.PBP

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



I need to debug it in psplink, but it creates an eboot and an elf instead of a prx!
Why?

A PRX is an ELF. And your PRX is "inside" the EBOOT.PBP. Comment out EXTRA_TARGETS = EBOOT.PBP and you'll get your PRX.

Why odes it always create a .elf?
I already tried using the elf but it doesn't work

Actually the only factor that controls if a prx gets created is the BUILD_PRX=1 line as far as I know.

You could manually create it by

Code:

psp-prxgen input.elf output.prx

It says something about not finding the export table, or something like that.
I checked the prx template, and the only thing differents are the libs....

Because as I said, PSP uses ELF executables, dude... And PRX are just a custom ELF type.

If you're exporting functions, make sure your exports file is set correctly.

I don't export anything..... :(
I mean, i don't need to export anything, and i don't have an export file

Your ELF must at least export module_start in syslib.

SDK will take care of that. I think the error he is getting is missing relocation table.

The real strange thing is that it doesn't compile a prx by itself.
I tryed compiling it manually:

C:\Documents and Settings\roberto\Desktop\platform\o-psp-c>psp-prxgen platform.elf platform.prx
Error, found no relocation sections

Maybe there is something wrong in my code?

The only "strange" thing i can tell, is that i use some extern "C" files (main is in c++)

EDIT: I made IT! I dunno what was the problem, but now it works!
But i have another problem when debugging....
The .elf file has the debug symbols, prx has not.
Why? Maybe something wrong in makefile?

You only need the debug symbols in the elf. you use the elf file as input for ie. psp-addr2line.

Or am i wrong?

I need to debug line to line the prx (psplink doesn't load the elf)
