Hey Guys,

I am attempting to compile the example code from libwiimote (and yes, I know this is not exactley WiiLi, but what the hell, right?)

The target machine is Ubuntu 7.10, gcc version 4.1.3 20070929 ( yes, g++ failed as well ), libwiimote4.0 ( 2.0 failed as well, same error )

Here is the code in question:

Code:

#include <stdio.h>
#include "wiimote_api.h"
int main()
{
   wiimote_t wi;
   wiimote_connect(&wi, "00:1B:7A:EB:28:30");
   wi.mode.acc = 1;             // enable accelerometer
   while (wiimote_is_open(&wi)) {
     wiimote_update(&wi);       // synchronize with wiimote
     if (wi.keys.home) {        // check if home key is pressed
       wiimote_disconnect(&wi);
     }
     printf("x=%d y=%d z=%d\n", wi.axis.x, wi.axis.y, wi.axis.z);
   }
 }



and the compile output is as follows:

Code:


/tmp/ccMso3FV.o: In function `main':
main.cpp:(.text+0x2e): undefined reference to `wiimote_connect(wiimote_t*, char const*)'
main.cpp:(.text+0x45): undefined reference to `wiimote_update(wiimote_t*)'
main.cpp:(.text+0x5b): undefined reference to `wiimote_disconnect(wiimote_t*)'
collect2: ld returned 1 exit status



Cheers,

Looks like you aren't linking the libwiimote stuff.

para -

going from standard to using nonstandard includes has been a bit rough for me, I am compiling code with this kluge of a command:

Code:

g++ main.cpp -o Wii -I /home/tag/Desktop/libwiimote-0.4/src/

( I know, I know )

what would the appropriate argument set?

Cheers,

I haven't used libwiimote, but you probably have to link it since it's looking for those functions at link-time and isn't finding them:

Code:
# g++ -c main.cpp -I /home/tag/Desktop/libwiimote-0.4/src/
# g++ main.o libwiimote.o -o Wii


Something like that.

Hey,

I have found the .so library and linked, but it still seems to be decidedly rebellious.

is wiiuse a better call, and if so what would the compile arguments look like?

Cheers,
