Hi everyone,

Finally, I’ve succeded to install the gnuradio 3.7.3 on fedora 20, even  
if  
it was my second time that I build it on fedora 20 !  
However, I’ve one more issue which concerns the importation of gnuradio,  
I  
receive this kind of error message:  
Cannot import gnuradio.  
I tried the following command:  
export PYTHONPATH=${PYTHONPATH};/usr/local/lib64/python2.7  
but it did change nothing !

Could someone help me fix this issue ? Thanks.

Well, I’ve built it from the source code 3.7.3 and I kept the default  
path  
(i.e. /usr/local).  
Moreover, my system knows perfectly the command lines concerning  
gnuradio  
(e.g. gnuradio-companion, gr\_modtool) but he crashes when I attempt to  
execute any of those commands.  
Is there anything else you want to know ?  
Thanks Martin.

I’ve found a post on same issue under the same title:  
[http://gnuradio.4.n7.nabble.com/Cannot-import-gnuradio-td42045.html](http://gnuradio.4.n7.nabble.com/Cannot-import-gnuradio-td42045.html)  
I tried to load the configuration by “ldconfig” after setting the path  
varaiables, and it works perfectly now.
