Problems linking a Wii example program [SOLVED]

---------------------------------------------
Hello,
I want to port a SDL game for the Wii, first of all, I have been trying to install the SDK since 3 last days with no success.
This is the code that I am using (a simple hello world, it doesn't use SDL).
I compile it with:
powerpc-eabi-gcc -O0 -g3 -Wall -c -fmessage-length=0 -c hello.c -I"/home/black/devkitPro/libogc/include" -I"/home/black/devkitPro/devkitPPC/powerpc-eabi/include/c++/4.4.2" -I"/home/black/devkitPro/devkitPPC/powerpc-eabi/include/c++/4.4.2/powerpc-eabi" -I"/home/black/devkitPro/devkitPPC/lib/gcc/powerpc-eabi/4.4.2/include" -I"/home/black/devkitPro/devkitPPC/powerpc-eabi/include"
Program compiles without problem.
I link it with:
powerpc-eabi-gcc hello.o -o hello -L/home/black/devkitPro/libogc/lib/wii -lwiiuse -lbte -logc -lm
and I get this (the same that you can find in this post: http://forums.devkitpro.org/viewtopic.php?f=3&t=1329):

Hello,
I want to port a SDL game for the Wii, first of all, I have been trying to install the SDK since 3 last days with no success.
This is the code that I am using (a simple hello world, it doesn't use SDL).
Code: Select all
#include <stdio.h>
#include <stdlib.h>
#include <gccore.h>
#include <wiiuse/wpad.h>
static void *xfb = NULL;
static GXRModeObj *rmode = NULL;
//---------------------------------------------------------------------------------
int main(int argc, char **argv) {
//---------------------------------------------------------------------------------
// Initialise the video system
VIDEO_Init();
// This function initialises the attached controllers
WPAD_Init();
// Obtain the preferred video mode from the system
// This will correspond to the settings in the Wii menu
rmode = VIDEO_GetPreferredMode(NULL);
// Allocate memory for the display in the uncached region
xfb = MEM_K0_TO_K1(SYS_AllocateFramebuffer(rmode));
// Initialise the console, required for printf
console_init(xfb,20,20,rmode->fbWidth,rmode->xfbHeight,rmode->fbWidth*VI_DISPLAY_PIX_SZ);
// Set up the video registers with the chosen mode
VIDEO_Configure(rmode);
// Tell the video hardware where our display memory is
VIDEO_SetNextFramebuffer(xfb);
// Make the display visible
VIDEO_SetBlack(FALSE);
// Flush the video register changes to the hardware
VIDEO_Flush();
// Wait for Video setup to complete
VIDEO_WaitVSync();
if(rmode->viTVMode&VI_NON_INTERLACE) VIDEO_WaitVSync();
// The console understands VT terminal escape codes
// This positions the cursor on row 2, column 0
// we can use variables for this with format codes too
// e.g. printf ("\x1b[%d;%dH", row, column );
printf("\x1b[2;0H");
printf("Hello World!");
while(1) {
// Call WPAD_ScanPads each loop, this reads the latest controller states
WPAD_ScanPads();
// WPAD_ButtonsDown tells us which buttons were pressed in this loop
// this is a "one shot" state which will not fire again until the button has been released
u32 pressed = WPAD_ButtonsDown(0);
// We return to the launcher application via exit
if ( pressed & WPAD_BUTTON_HOME ) exit(0);
// Wait for the next frame
VIDEO_WaitVSync();
}
return 0;
}
