Strange thing, im trying to work with the usb.h (which is strangely
stored under linux/usb.h. WHen i compile with gcc (im programming in
C not C++)I always get (for every function) something like this:
/tmp/ccK3I1O6.o(.text+0x28): In function `main':
: undefined reference to `usb_init'
/tmp/ccK3I1O6.o(.text+0x34): In function `main':
: undefined reference to `usb_find_busses'
/tmp/ccK3I1O6.o(.text+0x38): In function `main':
: undefined reference to `usb_get_busses'
this is beyond my knowledge, does anyone know what this means, and
how to fix it?
Thanks alot!!
