ziebell_marco at posteo dot de changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |ziebell_marco at posteo dot de --- Comment #11 from ziebell_marco at posteo dot de --- I have a similar problem If I compile the library gtkmm version 2.24.4 with LTO and gcc-5.3.0. If I use gcc-5.3.0 and the CFLAGS="-march=native -flto -O2" the library is missing the vtable for the class TreeViewColumn. Which leads to a linking error while compiling the program inkscape version 0.91. If I use gcc-5.3.0 and the CFLAGS="-march=native -flto -O2 -fno-devirtualize" the vtable is there and "inkscape" builds fine. I'm using gentoo linux on an x86_64 processor and binutils version 2.25. I've confirmed that the vtable is missing via: "readelf --dyn-syms -a -e -t -A -D -W /usr/lib64/libgtkmm-2.4.so | grep TreeViewColumn | grep _Z | c++filt" I can provide a build log of inkscape and gtkmm with the different CFLAGS combination.
