>If libvtv is a separate library (I've not looked) It is a separate library whose source is inside the gcc source folder. Much of the documentation for enabling vtable verify is for compiling gcc from source outside of Yocto and just references using the flag with ./configure when building gcc from source.
> I suspect there are tweaks needed to the gcc-runtime recipe to build it I put “—enable-vtable-verify” in the gcc-common include so it should have been picked up by gcc.bb, gcc-cross and gcc-runtime. I also tried adding to just gcc cross and gcc runtime recipes. I also looked at how the sanitizer libraries were being built with gcc-sanitizers, but was unable to get a working solution. I gave up to focus on other priorities, but figured I’d ask the list in case someone had come across this before.
