I have : my block is closely based on the howto example. It compiles fine on the x86 machine as well. I'm starting to point the finger at the gnuradio installation. It seems that in the /usr/lib/python2.6/site-packages/gnuradio/gr folder, the gnuradio_swig_py_runtime.py is the culprit. Is it a file that changes often from one version of gnuradio to the other ? Does it depend on the version of swig ?
