Re: ModuleNotFoundError while running unit test of the OOT

[Jeff Long]

That workaround doesn't make sense. The idea, though, is that some files need to be moved/symlinked so Python can see them. Or the PYTHONPATH needs adjustment.

This is also true on the latest dev/master, and it was possible to do a "make test" before "make install" in 3.8. This has been noted in https://github.com/gnuradio/gnuradio/issues/4825, which also includes a workaround.

Hi,

While creating a squaring OOT module (just as an example), my unit test failed because of ModuleNotFoundError.

This error occurs before running make install. After running make install module is available and test is passing ok but it doesn't make sense to do that. 

I am using 3.9.3.0 version of GNU Radio. I expect that after running make there will be a python module called square (as I named my OOT, am I correct?)  

Below is the output after running ctest -VV command:

Note: below output is obtained after running make install and then make uninstall (after make install, module is available and the is no error)
