Hi list,
I recently compiled gr-howto-write-a-block (from git master) and its
doxygen documentation is not loaded/displayed in gnuradio-companion.
The python code is installed in "${GR_PYTHON_DIR}/howto". See:
http://gnuradio.org/cgit/gnuradio.git/tree/gr-howto-write-a-block/python/CMakeLists.txt#n34
http://gnuradio.org/cgit/gnuradio.git/tree/gr-howto-write-a-block/swig/CMakeLists.txt#n51
In gnuradio-companion, when the python documentation is loaded, it
is assumed the blocks are in the "gnuradio" subpackage. See:
http://gnuradio.org/cgit/gnuradio.git/tree/grc/python/extract_docs.py#n32
In case I didn't miss something, what is the preferred way to fix
this ? (I say "fix" because I would expect the howto block to show
its doc in grc by default).
Solution 1: install third party blocks into the "gnuradio" package
(i.e. installing to "${GR_PYTHON_DIR}/gnuradio/howto").
Solution 2: modify gnuradio-companion so it can search outside the
"gnuradio" package. For testing purposes, I made the attached patch.
