Posted: Mon Jan 09, 2006 1:43 am Post subject: Alot of errors cause by png

Hi folks,

i get these error when trying to only compile a file with an include <"png.h"> coded no code used from that library yet.

Code:

psp-gcc -I. -I/usr/local/pspdev/psp/sdk/include -O2 -G0 -Wall -L. -L/usr/local/pspdev/psp/sdk/lib framebuffer.c graphics.c main.c ball.o -lpspgu -lpng -lpspdebug -lpspdisplay -lpspge -lpspctrl -lpspsdk -lc -lpspnet -lpspnet_inet -lpspnet_apctl -l
pspnet_resolver -lpsputility -lpspuser -lpspkernel -o out.elf
graphics.c:5:17: error: png.h: No such file or directory

It states that png.h is missing but when i copy that into my directory it gives al sorts of duplicate errors

what can i do to get it to work in Visual C++ (microsoft)

P.S. i have posted a sortwise post already but i posted it into a wrong thread it was a thread which i said was solved allready so sorry for the kind of doublepost.

Add -lpng to you makefile under LIBS. i.e. LIBS = -lpspgu -lpng -lz -lm

Your include path is set to look in the current directory and in /usr/local/pspdev/psp/sdk/include. If you have compiled and installed libpng the normal way, png.h will be installed in /usr/local/pspdev/psp/include. So modify your makefile or however that is done in Visual Studio, to add that directory to your include path also. _________________ Br, Sandberg

Hi, well i have -lpng in my makefile:

Code:

TARGET = out
OBJS = $(wildcard *.c) ball.o

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

LIBDIR =
LDFLAGS =
LIBS = -lpspgu -lpng -lz -lm

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

ball.o: ball.raw
bin2o -i ball.raw ball.o ball

<-- makefile

the makefile is run through a batch file :

Quote:

@REM Ne pas afficher les commandes
@ECHO OFF

ECHO Compilatie van het Project.

SET path=%path%;C:\cygwin\bin;C:\cygwin\usr/local/pspdev/bin
SET path=%path%;C:\cygwin\usr\include\libpng12
SET PSPSDK=C:\cygwin\usr/local/pspdev

make.exe

ECHO Effacer les fichiers inutiles
DEL *.o

ECHO Trouver le bon repertoire

SET DRIVE=.\

ECHO Cr�ation du PBP
MD %DRIVE%GAME2%%
Elf2pbpm -FILEOUT=%DRIVE%GAME2%%\EBOOT.PBP -TITLE="Game 2: 2D"

ECHO Renommer en EBOOT.PBP
MD %DRIVE%GAME2
MOVE out.elf %DRIVE%GAME2\EBOOT.PBP

which is now kind of a mess but i have put it there but don't know how to add the include path any sugestions

No need to add include path if you have install correctly zlib and png (make and make install), remove :

SET path=%path%;C:\cygwin\usr\include\libpng12

in your make.bat

Use #include <png.h>

Code:

graphics.c:5:17: error: png.h: No such file or directory

In a C or C++ program, always look at the first error. The compiler still isn't finding the png.h header file. You can set a path to search for include files right in your batch file. Just add something like the following to set an include path before you run make.exe:

set include=c:\pspdev\include;c:\pspdev\psp\include;c:\pspdev\psp\sdk\include;

You must change this line to match the configuration of your machine, just use semicolons ';' between directory names.

i'm sorry but i still can't get it to work. I searched the png.h and added that as include in the batch:

C:\cygwin\usr\include\libpng12 <--- in here the png.h exists
C:\cygwin\usr\include <--- in here a shortcut exists to png.h

i still get the same errors

I tried just copying the png.h and the pngconf.h to my sourcecode folder but then i get these errors:

If you install correctly libpng, the png.h will be in cygwin\usr\local\pspdev\psp\include and not in C:\cygwin\usr\include\libpng12.

For a good install, download libpng and zlib folders (svn://svn.ps2dev.org/psp/) and copy it in c:/cygwin/home/{your login}/

After open a cygwin shell and go into the c:/cygwin/home/{your login}/zlib and tape :

make

and after :

make install

Proceed the same with c:/cygwin/home/{your login}/libpng

After you can erase c:/cygwin/home/{your login}/zlib and c:/cygwin/home/{your login}/libpng folders.

No forget to add library in makefile : -lpng -lz -lm

Now the zlib and libpng are installed fine.

For the multiple definition, check your makefile and source if you compile same file several times or if you declare several times the same function.
