  Yes, I have looked at that header file.  I wrote a small program to
try using the usrp2 class and tried to compile it without success.

Code usrp_demo.cc:
#include <usrp2/usrp2.h>

int main()
  const char *interface = "eth0";
  const char *mac_addr_str = "00:05:2c:85:30:a7";

  usrp2::usrp2::sptr u2 = usrp2::usrp2::make(interface, mac_addr_str);

  /* do stuff here */

  return 0;

g++ Output:
address@hidden:~/usrp2-demo/usrp2-getdata$ g++ usrp2_demo.cc -o usrp2demo 
/usr/local/lib/libusrp2.so: undefined reference to
/usr/local/lib/libusrp2.so: undefined reference to
collect2: ld returned 1 exit status

Any idea on what I'm doing wrong?
