aim of meta modeling and code generation.

my computer.

package (gnuradio/gnuradio-example/python/audio) and now i have deceded
to write my block.
but before do it, i first try to execute the giving example qa_howto.py
from the package gr-howto-write-a-block/src/python and i got this
example:
Â
Traceback (most recent call test):
File “qa_howto.py”, line 24, in
  import howto
ImportError: no module named howto

The only way to run qa_howto.py is by running “make check” from the
top directory of gr-howto-write-a-block. It sets up a bunch of
environment variables required to run the QA code without it being
installed.

Hi Patrick,

You don’t say what os or even platform you are using but it sounds like
you
didn’t do a “sudo make install” on the howto stuff.

Or if you did, possibly you installed on ubuntu and the binaries went to
/usr/lib but your howto install went to /usr/local/lib.

unfortunately you don’t really give enough information to answer your
question, I don’t think. :slight_smile:
