Hello, OS: Ubuntu 14.01.1 gnu-radio: 3.7.6 Dell Optiplex 765 I am having trouble using the B210 USRP in two channel mode. Things work well when I use grc to configure the B210 with one channel, but when I try using two channels, I get the error shown below. This is quite similar to a problem

Yes I did ./pybombs remove, which uninstalls everything. I also have pybombs set to install everything from source, so I know for sure what's being installed. All but PyQWT, because that source install is broken for some reason. So the process is, I begin with ./pybombs install gnuradio This

I'm fighting a similar kind of error with QT right now. I'll pass along some debug that I was asked to do. First open a terminal and execute the following: ldd /usr/local/lib/libgnuradio-mimo.so | grep libgnu Then search for the file it reports back like this: sudo find / -name 'filename.so*'
