I don’t think anyone managed to create gtkmm 3 for Windows 64 bit or is it aware of a good build?
There are about 3-4 links on Google where people tried this, but for various reasons I can’t get them to work. Either the pkg-config files are missing (so I can’t compile any programs), or I get style error messages incompatible .dll.a, or the programs just crash.
I tried to build it myself and failed because I don't think I'm experienced enough, and I tried to talk about the gtkmm mailing list and no one answered. There are official win64 installers, but only for gtkmm 2.
