Dear Tom,Thanks for your advice.Actually, I've got a trouble for days installing Thrift and enabling it from GNU Radio.This is just a simple wrap-up for readers who are not familiar with compiling and building things.)Installing thrift:1. Get Thrift 0.9.20.9.2 release tag of git repository have some buggy stuff.2. Extract it and build. Make sure that you have all of pre-requisites.$ tar xf thrift-0.9.2.tar.bz2$ cd thrift-0.9.2$ ./configure$ make$ sudo make install$ sudo ldconfig # just in case3. Check python can import Thrift$ python>>> import thrift3-1. If python can't, do the followings:$ cd thrift-0.9.2/lib/py$ sudo python setup.py installGo back step 3. And check again.4. Build GNU Radio.$ cd gnuradio$ mkdir build$ cd build$ cmake ..$ make$ sudo make isntall4-1. One important thing is, I recommend you to delete everythink inside build directory.At least, I recommend you to remove CMakeCache.txt:$ cd build$ rm -rf ./# or$ rm CMakeCache.txtThis file can help executing cmake, but sometimes it makes cmake get wrong variables.I've spent days to figure out this. cmakek gives me a wrong thrift binary path /usr/bin/thrift.Actually, I have thrift under /usr/local/bin.I think it's a quite unusual case since I have been messing around my PC.If you have a system with some fresh installation and configuration, it won't be a problem.Regards,Jeon.

Jeon.Regards,Could anyone give me a hint for this?I am trying to measure performance of my OOT module with performance counter and control port.When I execute a command line `gr-perf-monitorx` or `gr-ctrlport-monitor`, an error below occurred:
File "/usr/local/lib/python2.7/dist-packages/gnuradio/ctrlport/GrDataPlotter.py", line 26, in <module>
from gnuradio.ctrlport import GNURadio
ImportError: cannot import name GNURadio
For detail information, I've installed GNU Radio with `build-gnuradio` script. The last commit of cloned git repository in my PC is `d5cea6e4(https://gnuradio.org/redmine/projects/gnuradio/repository/revisions/d5cea6e44e29db6b62fabe2b1e5ec16e91b41e68)` in Jun 22 2015. I can't remember exactly, but I think this commit was used to install the GNU Radio.
This sounds as if Thrift wasn't found when running cmake. Our cmake scripts use thrift to compile our gnuradio.thrift file into C++ and Python code that is installed with GNU Radio.The output of cmake will tell you if it found Thrift or not. Look under the list of enabled components for:-- * gr-ctrlport-- * * thriftTom
