Alex, The "make check" command invokes run_tests which run everything that matches qa_*.py (qa_howto.py)and return the final result. It will bypass the default PYTHONPATH and set your own built tree in which search for your C++/python files. You can find these settings in run_tests: ---------------------- # Where to look in the build tree for our shared library libbld=/home/yuan/Desktop/SDR/built/src/lib # Where to look in the src tree for swig generated python code libsrc=/home/yuan/Desktop/SDR/built/src/lib # Where to look in the src tree for hand written python code py=/home/yuan/Desktop/SDR/built/src/python
# Where to look for installed GNU Radio python modules # FIXME this is wrong on a distcheck. We really need to ask gnuradio-core # where it put its python files. installed_pythondir=/usr/lib/python2.6/dist-packages installed_pyexecdir=/usr/lib/python2.6/dist-packages PYTHONPATH="$libbld:$libbld/.libs:$libsrc:$py:$installed_pythondir:$installed_pyexecdir:$PYTHONPATH" #PYTHONPATH="$libbld:$libbld/.libs:$libsrc:$py:$installed_pythondir:$installed_pyexecdir" ------------------------------------- Also, I think there's another way which could run qa_howto.py directly. As howto.py has already been generated by SWIG, you can find it under python sys.path directory: /usr/lib/python2.6/dist-packages/gnuradio While the command "import howto.py" in qa_howto.py will try to import that file from /usr/lib/python2.6/dist-packages (howto.py's parent directory), but it is not there. You can modify this command as "from gnuradio import howto" to import howto successfully. Hope it will help.
