Hi there, Could someone help me fix this issue, when I try to run my tests, the ctest returns the following: … from gnuradio import gr, gr\_unittest ImportError: No module named gnuradio … Nonetheless, when I import any module from gnuradio in python terminal, it passes without any problem, and I can also run gnuradio-companion ! which I found very strange. Thank you in advance.

And how did you install it in the first place? When you ran cmake, did you see that “testing-support” was enabled? And, just to make sure, you are running ctest within the build directory, right?

Hi Tom, Thank you for your prompt response. I use 3.7.3 version, I’ve installed it from the source. Here is what “cmake -Wno-dev ../” returns: * * * – Build type not specified: defaulting to release. – Boost version: 1.54.0 – Found the following Boost libraries: – filesystem – system Checking for GNU Radio Module: RUNTIME – checking for module ‘gnuradio-runtime’ – package ‘gnuradio-runtime’ not found - INCLUDES=/usr/local/include - LIBS=/lib64/libgnuradio-runtime.so GNURADIO\_RUNTIME\_FOUND = TRUE – Configuring done – Generating done – Build files have been written to: /xxxxxxxxxxxx/build * * * So there is no “testing support”, and yes, I’m running ctest within build directory. This a little bit strange, cmake didn’t find the runtime for the first place ! I appreciate anything would help.

This doesn’t make sense. This looks like you’re trying to build your own OOT module, not GNU Radio itself. So are you trying to run ctest on your own code or actually run GNU Radio’s test suite? And what’s happening with the "package ‘gnuradio-runtime’ not found’ is that pkg-config is not finding the .pc file, which means it’s not in a path known to it (see PKG\_CONFIG\_PATH). However, cmake continued to look explicitly for the headers and libraries and found them, which is why GNURADIO\_RUNTIME\_FOUND = TRUE. It’s very odd that you have the headers in /usr/local and the library in /lib64, though. I’m thinking that this might have something to do with your ctest issue. Tom
