i wrote a child class by hand
i managed to compile successfully using the commands below :
cmake ..
gr_modtool makexml header_format_cc1101 (no suitable file found because there is no _impl.cc file)
sudo make install
sudo ldconfig

but my module is not detected in grc

Param - Value(value):
    Value "f4gsw.header_format_cc1101(digital.packet_utils.default_access_code, 3, Const_PLD.bits_per_symbol())" cannot be evaluated:
    name 'f4gsw' is not defined

hi all
i'm trying to derive the header_format_base with no success
i created a new module with modtool and the "no block" profile
i copied and modified the "header_format_default" sources but i get swig error
telling me that sptr is not defined

did someone ever managed to write its own header format with modtool ?
is modtool the way to go ?
which modtool profile do i need to use ?
do you have some hints for doing so ?

i can read and write (kind of) some C++ code but i do not know anything about SWIG. that is black magic for me, so please i would be glad if someone explain me step by step ;)
thank you all
