Here are the steps I would take: 0) get the latest UHD release, build, and install it 1) in your gnuradio root build directory, remove CMakeCache.txt 2) rm gr-uhd/* (in the build directory!) -- this shouldn't be necessary, but it'll make sure that everything is rebuilt here. 3) rerun cmake and make sure it's picking up uhd as a component 4) rerun make and make install 5) test again to see if that fixes the problem Tom ***************************************************************** Thanks Tom. I checked under /usr/lib64/python2.7/site-packages/gnuradio/ and it looks as if uhd is installed. I found a directory named "uhd" that appears to be configured as a python module (contains __init__.py file) as well as the following: __init__.py __init__.pyo uhd_siggen_base.pyc uhd_swig.py uhd_swig.pyo __init__.pyc uhd_siggen_base.py uhd_siggen_base.pyo uhd_swig.pyc _uhd_swig.so Could it be that the gtlib_swig module should be importing it as "uhd" versus "uhd_swig", and that is why it is not found?
