Problem with USE_PSPSDK_LIBC = 1 and libpng

[Tsukasa]

Hi Guys :(

I've a difficult problem with my program.
I have to use the "USE_PSPSDK_LIBC = 1" tag in the makefile, but then, my libpng won't work :/

Here is the error message:

Can anyone help me :'(?

relocation truncated to fit: R_MIPS_GPREL16 against `_impure_ptr'

Libpng was not built with -G0.

undefined reference to `_impure_ptr'

It was built against newlib.

my Makefile looks like this:

USE_PSPSDK_LIBC = 1

what could be happening

NOTE: the output is in spanish but all output is similar to the posted by Tsukasa

[dot_blank]

R2k: tienes el mismo problemo que esta passando
con Tsukasa ...el problema es que cuando tu make
libpng, la libreria no se construo come debe que ser

usted debe abrir el file Makefile en la directoria libpng
y cheqea que esta linia es exacto como debajo

CFLAGS = -O2 -G0

y guantar el file Makefile y vaz pa' tu cmd shell y
make y make install outra vez

[R2k]

i checked the libpng's makefile and has the -O2 -G0
see:

Code: Select all

PSPSDK=$(shell psp-config --pspsdk-path)
PSPDIR=$(shell psp-config --psp-prefix)
TARGET_LIB = libpng.a
OBJS = png.o pngerror.o pngget.o pngmem.o pngpread.o \
	pngread.o pngrio.o pngrtran.o pngrutil.o pngset.o \
	pngtrans.o pngwio.o pngwrite.o pngwtran.o pngwutil.o

CFLAGS = -O2 -G0

include $(PSPSDK)/lib/build.mak

install: $(TARGET_LIB)
	@echo "Installing libpng into $(PSPDIR)"
	@mkdir -p $(PSPDIR)/include $(PSPDIR)/lib
	@cp png.h pngconf.h $(PSPDIR)/include
	@cp libpng.a  $(PSPDIR)/lib
	@echo "Done"

but i did again the make , make install thing and the result is the same

[R2k]

please someone help me this error is really pissing me off ...

[BlackDiamond]

add "USE_PSPSDK_LIBC = 1" to libpng's makefile or type "make USE_PSPSDK_LIBC=1 install" (after running "make clean" of course)

[danzel]

I'm going to say that libpng is compiled against newlib (as has been said) when you need to compile it against pspsdk-libc.

Try add:
USE_PSPSDK_LIBC = 1
To the makefile for libpng and compile+install it again.
(Don't know if this is enough)

Why do you need to use the pspsdk libc in the first place?

edit: just beaten ;)

i added USE_PSPSDK_LIBC = 1 and the linking looks better but i'm still have a error in linking something about ... time.h and gmtime(...)

this is the output:

i'm using only to see the performance of old libs ... but i'm thinking in forgive this crazy stuff !!!

[0xAVGP]

Anyone solved the problem?
I got this prob too...
the thing is: I got the Win32-Toolchain here, therefor: Has anyone a properly linked libpng for me :)
Thx in advance

[Jim]

I'd be tempted to just add a stub for gmtime().

It worked for me.

Using the current libpng version 1.2.8 and zlib 1.2.2

Inserted the line "USE_PSPSDK_LIBC = 1" into the makefiles of both libpng and zlib.

First in the zlib folder:
make clean
make
make install

Then in the libpng:
make clean
make
make install

Then make own project and all errors gone.
