[Discuss-gnuradio] Difficulty with "howto" tutorial

[Andrew Spielberg]

Hi,

I don't know if the how to tutorial is out of date, but I cannot find any Makefile.am file in the "gr-howto-write-a-block" that looks like example 5 in the tutorial (http://www.gnu.org/software/gnuradio/doc/howto-write-a-block.html#prereqs).  I've tried editing the libs to the best of my ability, but the best that I can get from the make check is 

make  check-am
make[1]: Entering directory `/home/aespiel1/gnuradio/gr-howto-write-a-block/python'
make  check-TESTS
make[2]: Entering directory `/home/aespiel1/gnuradio/gr-howto-write-a-block/python'
/home/aespiel1/gnuradio/gr-howto-write-a-block/lib:/home/aespiel1/gnuradio/gr-howto-write-a-block/lib/.libs:/home/aespiel1/gnuradio/gr-howto-write-a-block/swig:/home/aespiel1/gnuradio/gr-howto-write-a-block/swig/.libs:/home/aespiel1/gnuradio/gr-howto-write-a-block/python:/usr/local/lib/python2.7/dist-packages:/usr/local/lib/python2.7/dist-packages:
Traceback (most recent call last):
  File "./qa_howto.py", line 24, in <module>

from a make check on the python library.  I know it's probably very wrong (I have little experience with editting makefiles, but my current makefile configuration in the /lib folder is attached below.

So is the howto tutorial just out of date, or did I mess something up (more probable)?  Please let me know if you have any suggestions.

Thank you very much for your time,
Andy S.
