[Discuss-gnuradio] gr-usrp library

[Ges]

Hi Eric,

The mail previous to the one below is there on the mailing list.

Anyway, what I was trying to do was try to get some code that I wrote using the usrp1_source_c functions to work. I was trying to link with the gnuradio-core libraries. Later I realised that these files are not complied in the gnuradio-core library. I saw the _usrp1.so lib file in .libs directory. But this contains all the swig related symbols in it as well. 

So, I then made a different shared library using the .o files and I was able to link my code with it. 

I was basically trying to find out if there is some shared library for the gr-usrp code with which I could link my C++ code. 

Thanks,
Gesly
