cant include usb.h

Hello Folks,

I think this is a very nooby question but i cant figure this out. Just for fun i want to acces USB interfaces on a ubuntu system. now ik have installed USBLib-dev it is located on:

Code:

/usr/src/linux-headers-2.6.28-15-generic/include/linux/usb.h

now i would like to use USB.h in one of my C++ applications. So i thought

Code:

#include <iostream>
#include <usb.h> //also tried #include "usb.h"

int main()
{
usb_init();
return 0;
}

This gives me this error:

Code:

/media/DATA/Jelte/Programming/C++/USBLib-dev TEST/USBFindBusses/main.cpp|6|undefined reference to `usb_init'

do you people see what i did wrong? is the including not correct or..?

As IDE i use Code::blocks with gcc (Ubuntu 4.3.3-5ubuntu4) 4.3.3

Thanks for your help.

Jelte,

Undefined reference is a linker error, not a compiler error.

You need something like
gcc prog.c -lusb
assuming the library is called libusb.a

That's just a guess, you can find out the real library name yourself.
