@SPlatten

@J-Hilk said in undefined reference to `vtable for:

@SPlatten are you sure config.c is party of your project ? :D so the linker can find it

?? Look at actual linker statement being executed?

Hmm, originally you showed

.build/config.o: In function asv::scm::helm::staledata_t::staledata_t()':

immediately above the undefined reference to vtable message. Is that still present? Because that does imply the linker is trying to pull in config.o, which would imply it does appear on the linker command line.... Is that indeed the right .build/config.o path for the config.o you keep rebuilding?

@SPlatten

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?

[JonB]

@JoeCFD
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++!

[JoeCFD]

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

@JoeCFD
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?

[JoeCFD]

@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

@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
