I'm struggeling in using gtkm3.0.
I've installed gtkm3.0 and pkg-config and MSys2 by strictly folowing
https://wiki.gnome.org/Projects/gtkmm/MSWindows (pretty clear step by step).
Then I arrived upto the critical point to test with the proposed simple code
and... it returns an error: "'mutex' does not name a type". Reading at some tuto on internet
https://stackoverflow.com/questions/14191566/c-mutex-in-namespace-std-does-not-name-a-type but not only, I've discovered that this issue was cleared with the MinGw64 x64 as it handles threading. Then I installed MinGw64 x64 (with pacman -S mingw-w64-x86_64-gcc) and setup the correct compiler toolchain in C::B (or at least, I think I'm good on that point).
However, even doing all these steps I still have a collection of errors (see below the first lines but their are 20 of them) .
I may have missed something somewhere. Can someone guide me?
undefined reference to `___gxx_personality_sj0`
undefined reference to `___ZN4GLib7ustringD1Ev`
undefined reference to `___ZN3Gtk6WindowC1ENS_10WindowTypeE`
I'm kind of lost... Thank for your help,
