Re: [Discuss-gnuradio] problem building gr-howto-write-a-block-cmake

[Achilleas Anastasopoulos]

I also noticed the following in the cmake ../

-- Found SWIG: /usr/bin/swig (found version "2.0.4")
-- Could NOT find PythonLibs (missing:  PYTHON_LIBRARIES)
-- Found PythonInterp: /usr/bin/python2.7


what is the significance of not founding the PythonLibs?
when i build gnuradio it says that it found them....


-- Configuring python-support support...
--   Dependency PYTHONLIBS_FOUND = TRUE
--   Dependency SWIG_FOUND = TRUE
--   Dependency SWIG_VERSION_CHECK = TRUE
--   Enabling python-support support.
--   Override with -DENABLE_PYTHON=ON/OFF
