[Discuss-gnuradio] Creating a USRP2 C++ Object

[Mike Leferman]

I'm working on a C++ program which directly creates an instance of a USRP2 object.  When the program is being run, the following error is thrown:

/usr/local/lib/libusrp2.so.0: undefined symbol: _ZN5gruel7sys_pri13usrp2_backendEv

Gruel was complied on the system and programs have been run using the usrp2 in gnuradio.  

What in the world does this error message mean, what could be throwing it and how can I fix it.  Thanks!
