-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi BZS,
just use gr_modtool to generate a block of the same type (sync/hier/general/...) and then modify the include/blockname.h to inherit from the file you want. You will also have to use set(GR_REQUIRED_COMPONENTS RUNTIME BLOCKS) in the top-directory CMakeLists.txt (if the base class is in gnuradio::blocks, otherwise replace BLOCKS by that module). Problem is, that inheriting from the in-tree classes won't help you much in terms of functionality. Class structure of OOTs as well as in-tree modules is usually (let's assume we're talking about a block called bzt_block): bzt_block: Specified only in include/bzt_block.h. Most methods are purely virtual. Does not do anything, but specifies an interface to use, and an shared_pointer factory (make) that returns a shared pointer to an instance of a subclass bzt_block_impl: subclass of bzt_block. Declared in lib/bzt_block_impl.h, defined in lib/bzt_block_imp.cc. Has all the methods. This class is usually hidden from "outside the module", and is only accessed as an instance of the bzt_block base class.
