Hi Walter,

thank you for your help,

I made the changes you suggested and now got an different error ... it
still does not compile. 

Here is the output:
x86_64-pc-linux-gnu-g++ -DHAVE_CONFIG_H -I.    -pthread -I/usr/include/gtkmm-2.4 -I/usr/lib64/gtkmm-2.4/include -I/usr/include/giomm-2.4 -I/usr/lib64/giomm-2.4/include -I/usr/include/pangomm-1.4 -I/usr/lib64/pangomm-1.4/include -I/usr/include/gtk-2.0 -I/usr/include/gtk-unix-print-2.0 -I/usr/include/atkmm-1.6 -I/usr/include/gdkmm-2.4 -I/usr/lib64/gdkmm-2.4/include -I/usr/include/glibmm-2.4 -I/usr/lib64/glibmm-2.4/include -I/usr/include/glib-2.0 -I/usr/lib64/glib-2.0/include -I/usr/include/sigc++-2.0 -I/usr/lib64/sigc++-2.0/include -I/usr/include/cairomm-1.0 -I/usr/include/pango-1.0 -I/usr/include/cairo -I/usr/include/pixman-1 -I/usr/include/freetype2 -I/usr/include/libpng14 -I/usr/lib64/gtk-2.0/include -I/usr/include/atk-1.0     -Wall -march=native -O2 -pipe -msse3 -MT mainwnd.o -MD -MP -MF .deps/mainwnd.Tpo -c -o mainwnd.o mainwnd.cpp

To not to pollute the mailing list again with a dozen of outputs and
logs I haven't attached those to this different posting. If you need
a certain file/log/output or whatever to fix this, please let me now!
:)

Best regards,
