Hi all, I am trying to make my OOT block respond to changes in its parameter the same way the Add Const block behaves. I want my block to update its value as and when the user slides the qtgui range. I notice this is not done by default. I added the same `add_rpc_variable` function defined in `gr-blocks/lib/add_const_ff_impl.cc`. I replaced the appropriate variable/function names with my own. However, I get the following error.
``` error: no matching function for call to ‘rpcbasic_register_set<gr::my_OOT::reactionFunction_impl, float>::rpcbasic_register_set(std::string, const char [9], void (gr::my_OOT::reactionFunction_impl::*)(int), pmt::pmt_t, pmt::pmt_t, pmt::pmt_t, const char [1], const char [16], priv_lvl_t, const uint32_t&)’ 225 | DISPNULL))); ``` I imported the same header files that `add_const_ff_impl.h` and `add_const.h` import. What does the error mean. What have I done incorrectly? I couldnt find a thread describing the same problem in the archives. Does someone have an easier way to do what I wanna do? Thanks. Cheers, Sol
