Hi
I have application using gtkmm.2.4 which used to compile and link without problems.
After a recent update and switch tto gcc 6.4.0 i get linking errors:
-----
xbv.o: In function `xbv::setImage(char const*)':
/home/jody/progs/QHG3/trunk/visual/xbv.cpp:1641: undefined reference to `Gtk::Image::set(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)'
/usr/lib/gcc/x86_64-pc-linux-gnu/6.4.0/../../../../lib64/
libgtkmm-2.4.so: undefined reference to `Glib::ustring::ustring(std::string const&)'
collect2: error: ld returned 1 exit status
-----
I use `pkg-config gtkmm-2.4 --cflags` to compile those files actually using gtkmm, and `pkg-config gtkmm-2.4 --libs` to link the application.
The gtkmm version i have installed seems to be 2.24.4-r2; my OS is gentoo (linux-3.16.5-gentoo).
