Hello Marcus,
I have made it work, by checking some of your answers before. Here are the
steps, in case someone else is interested:
1. define the set_param() function in lib/myblock_imp.h file:
Public:
...
void set_param(float param) {_param = param;}
2. Add in the lib/myblock_imp.cc file:
_param = param;
3. In include/gnuradio/customModule/myblock.h add:
Public:
...
virtual void set_param(float param) = 0;
4. run "md5sum include/gnuradio/customModule/myblock.h" to get the tag
value.
5. copy and paste the tag value in "BINDTOOL_HEADER_FILE_HASH(xxxx)" in the
file python/customModule/bindings/myblock_python.cc
6. then do cmake../, make, sudo make install and sudo ldconfig. It should
work now.
7. I also did "gr_modtool bind myblock", but I'm not sure if it helped or
not.
Best regards,
Wei
