I'm trying to do a clean installation on a PC running Ubuntu 16.04. Originally, GNU Radio was installed by the build-gnuradio script. However, my new USRP board had a different ABI. I decided to redo the installation. Using the script was pretty smooth the last time I used it. After a very long painful day, I got the build to go as far as 100% by issuing the command bash ./build-gnuradio -v -m. However, there is still an error as shown below

    Scanning dependencies of target pyuhd
[ 99%] Building CXX object python/CMakeFiles/pyuhd.dir/pyuhd.cpp.o
[100%] Linking CXX shared library libpyuhd.so

[100%] Generating build/timestamp
Traceback (most recent call last):

I have used the build-gnuradio so many times in the past but things are quite painful now. Any input will be appreciated.

I had the same problem using pybombs. It seems that the issue happens when you have both python2 and python3 installed. In that case, the cmake script in (UHDSRC)/host/python/CMakeLists.txt erroneously defaults to python3.

I have fixed the issue by replacing the mention of ${PYTHON_EXECUTABLE} around line 68 with ${PYTHON2_EXECUTABLE}

Not sure this change is desirable for the upstream project.
