--- Comment #3 from Jonathan Wakely <redi at gcc dot gnu.org> --- (In reply to gcc-user from comment #2) > Briefly it explained that -lvtv comes from -fvtable-verify=std in a gcc spec > file and is propogated to Makefile.in by gcc/Makefile.def. The -fvtable-verify=std doesn't come from the spec file, it comes from using --enable-vtable-verify to configure gcc. That adds -fvtable-verify=std and the spec file turns that into -lvtv. I don't know why you want to use --enable-vtable-verify but it's not really maintained as far as I can see.
