can't solve "conflicting types Problem" [SOLVED (s

[mgschwan]

Hello

i have been searching around in the forums for quite a while but i can not find a solution to my problem. I even can't find someone who had the exact same problem.

i am running gentoo linux and installed the psp toolchain (by first downloading it, updating it via svn and then compiling and installing it). I also installed the pspsdk (first i tried the binary version and then i checked it out from svn and compiled it)

So far so good

But if i try to compile for example the lines demo in the psp-sdk i get the following error

Code: Select all

make: *** [lines.o] Error 1

I get this error for most of the samples and also if i try to compile the zlib. But for example the controller demo compiles without this error.

I would be really happy if someone could give me a tip as my head already hurts from constant banging on the table :)

I'm not sure about the 'declared inside parameter list' error, but it sounds like your include paths aren't set up right.

lines.c (line13) should just be:

Code: Select all

#include <stdio.h>

but it looks like you have:

Code: Select all

#include <../../../../../psp/include/stdio.h>

So it's pulling in separate definitions - once from

/usr/local/pspdev/psp/sdk/include/sys/stdio.h

and another from:

/usr/local/pspdev/psp/include/stdio.h

It might be helpful if you could post the first dozen or so lines from lines.c and your makefile?

[mgschwan]

Ok here is the Makefile (i used the sample Makefile provided with the lines.c)

Code: Select all

TARGET = lines
OBJS = lines.o ../common/callbacks.o ../common/vram.o
PSPSDK=$(shell psp-config --pspsdk-path)

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

LIBDIR = 
LDFLAGS =
LIBS= -lpspgu

EXTRA_TARGETS = EBOOT.PBP
PSP_EBOOT_TITLE = Lines Sample

include $(PSPSDK)/lib/build.mak

This is the beginning of the lines.c (without the License comments)

Code: Select all

#include <pspkernel.h>
#include <pspdisplay.h>
#include <pspdebug.h>
#include <stdlib.h>
#include <stdio.h>
#include <math.h>
#include <string.h>
#include <time.h>

#include <pspgu.h>

#include "../common/callbacks.h"
#include "../common/vram.h"

And this is the output of make. I added -v as a CFLAG to get more output

Thanks in advance for any advice

Well i solved this Problem but i'm not really sure why i solved it.

I deleted the pspdev directory and installed it completely from scratch again (but now into my home directory and not into /usr/local) and i used the -a option with the toolchain command.


Now everything works without an error.
