Hi all:  
Thank you in advance.  
I encouter an error:  
linux; GNU C++ version 4.6.3; Boost\_104800;  
UHD\_003.007.000-133-g6bd9fed2  
GR-UHD detected ABI compatibility mismatch with UHD library.  
GR-UHD was build against ABI: 3.7.1-0,  
but UHD library reports ABI: 3.7.0-0  
Suggestion: install an ABI compatible version of UHD,  
or rebuild GR-UHD component against this ABI version.  
I find someone tell: Uninstall all GNU Radio and UHD packages from the  
Ubuntu software center.But I don’t uninstall gnuradio and uhd.And i  
think upgrade the uhd will be ok.Is it right?And how to upgrade uhd?Can  
someone explain it to me?Thank you.  
Best regards,  
xd

Hi xd,

the right way to do is to uninstall all gnuradio and UHD from the Ubuntu  
package repositories and reinstalling both from source.  
The problem you are experiencing is happening _exactly_ because gr-uhd  
(as a part of GNU Radio) was built with a different version of UHD, so  
please make sure they match.

Greetings,  
Marcus
