Re: [Discuss-gnuradio] Error with gnuradio 3.8 and python 3

[Mark Koenig]

Michael,

 

On line 37, I see the following text.

 

set(ENABLE_PYTHON ON CACHE BOOL “Enable Python & Swig”)

 

So it looks like it is enabled.

 

I added ‘include(GrPython)’ to my CMakeLists.txt file and now it is pulling the wrong python interpreter.  I want to use Python 3.

 

#9 2.642 -- Found PythonInterp: /usr/bin/python (found version "2.7.15")

#9 2.652 -- Found PythonLibs: /usr/lib/x86_64-linux-gnu/libpython2.7.so (found suitable exact version "2.7.15+")

#9 2.688 -- Found SWIG: /usr/bin/swig3.0 (found version "3.0.12")

#9 2.693 -- Found PythonLibs: /usr/lib/x86_64-linux-gnu/libpython2.7.so (found version "2.7.15+")

 

Further down my dockerfile output I am seeing the following, which I believe is because CMake is using the wrong python interpreter.

 

-- Checking for module 'thrift'

#9 3.454 --   Found thrift, version 0.10.0

#9 3.553 -- Python checking for Thrift - not found

#9 3.555 -- Could NOT find THRIFT (missing: PYTHON_THRIFT_FOUND THRIFT_FOUND)

#9 3.561 CMake Warning at CMakeLists.txt:24 (find_package):

#9 3.561     /opt/truearrow/6.3/lib/cmake/gnuradio/GnuradioConfig.cmake

#9 3.561

#9 3.561   but it set Gnuradio_FOUND to FALSE so package "Gnuradio" is considered to

#9 3.561   be NOT FOUND.  Reason given by package:

#9 3.561

#9 3.561   The following imported targets are referenced, but are missing:

#9 3.561   gnuradio::gnuradio-runtime

 

 

Any help would be greatly appreciated.

Hi Mark - Interesting issue. Is SWIG/Python -not- enabled in your GR install? Following the code, that could cause the error you're seeing. If you look through the file "/opt/truearrow/6.3/lib/cmake/gnuradio/GnuradioConfig.cmake", line 37 will show whether ENABLE_PYTHON is enabled or not. - MLD
