I've decided to follow your suggestion and get gr_modtool.py.
First I created the module with this script which created some folders, files
and the .cc and .h files with skeleton code.
Then I put my code in the .cc and .h files. I also changed the .xml file so I
can use GRC (I haven't used python yet to create graphs).
After this, I used cmake. I wrote:
>sudo make install
These were my steps to build a new block to use in GRC. However, I get this
packages/mycoolstuff/_mycoolstuff_swig.so: undefined symbol:
Yes. My module and block are called mycoolstuff and decimated_average_vcc.cc
It seems that there is a problem with the swig. Do I have to configure anything
in the .i files before starting to use cmake?
