Re: [Discuss-gnuradio] UHD won't work with GRC

[Scott Johnston]

All,

I think I am having a version problem. I followed the instructions from 
the gnuradio and UHD Start page.
I download gnuradio using

$ git clone git://gnuradio.org/gnuradio
git branch --track next origin/next
git checkout next

And then I do the usual

./bootstrap
./configure
make
make check
sudo make install
sudo ldconfig

Everything goes fine and everything that I expect to get installed does, 
but then as soon as I try to run something it breaks, see errors below. 
I dug further, and I think I have a version problem. Both the version.sh 
file in my gnuradio directory and the gnuradio-core.pc file in 
/usr/local/lib/pkgconfig say the version in 3.4. But when I run 
./configure it says the version is 3.3.1. As far as I know version 3.4 
doesn't exist yet. I have uninstalled and deleted everything and 
reinstalled and the problem remains the same.

Anybody what the problem is?

TIA

Scott

I get the following problem when trying to run any gnuradio programs.
And when I try gnuradio-companion a gui pops up that says "can't import
gnuradio, are your PYTHONPATH and LD_LIBRARY_PATH set correctly?
