I am trying to compile a program that uses libusb library in Ubuntu 12.04.

I have installed the libusb-1.0-0-dev. However, when I try to compile a program as below:

#include<usb.h>

#include<stdio.h>

#include<libusb-1.0/libusb.h>

int main()

{

       libusb_init(NULL);            

       return 0;

}

It gives me an error saying

/tmp/ccb75YtE.o: In function 'main':

usb.c:(.text+0x11): undefined reference to 'libusb_init'

collect2: ld returned 1 exit status

I am using the command cc <file name> -lusb to compile it.
What could be the problem?

Try changing the -lusb to -lusb-1.0, like this:

$ cc <file name> -lusb-1.0
