    soooo, since you'e not using m_nextUDN anywhere else and its private.... have you considered simply using:

    static uint16_t nextUDN() {
            static uint16_t m_nextUDN = 0;
            return ++(m_nextUDN);
        }
    

    ?

        @SPlatten not config.cpp or config.cc? it is not c code, right?

          It it were compiled as C code, it wouldn't begin to compile :) So I think we can assume whatever his file extension it's being compiled as C++!

            @JonB it is wrong and should be changed since gcc(not g++) will be applied for it.

              I'm guessing he has been using this for a while, seems strange this one and only error would show up now.

              @SPlatten
              I don't know whether this matters with gcc/g++. Do you want to show us the complete command-line being used to compile your config.c file?

                @JonB with flag -x gcc will work for c++ code as well. But it is better to separate c and c++ code with .c and .cpp

                      Yeah, but is that "global scope", i.e. not inside anything else?

                      @J-Hilk
                      The trouble is, without m_nextUDN defined properly, I do not get

                      undefined reference to vtable for asv::scm::helm::staledata_t'

                      message, I get complaint about m_nextUDN not being defined....

                      @JonB , sorry to do this, can you please delete any posts where you have quoted my text or edit to remove quoted text. I am in trouble as I have mentioned project names in my posts that I should not have and as a result my contract has been terminated.

                      Thank you,
                      Simon
