gtkmm y Win32
Una de las mayores ventajas de gtkmm es que es multiplataforma. Los programas de gtkmm escritos en otras plataformas como GNU/Linux generalmente pueden transferirse a Windows (y viceversa) con pocas modificaciones al código fuente.
The latest stable gtkmm currently works with the MinGW-w64/GCC4.8 compiler and Microsoft Visual C++ 2015 or later (including the freely available express/community editions) on the Windows platform. There is an installer available for gtkmm on Microsoft Windows, albeit for older versions of gtkmm. Please be aware that although normally it is fine to mix builds done with Visual Studio 2015, 2017 and 2019, please do not do so when building gtkmm with its -mm dependencies.
Refer to the README.win32, as well as the README files in the gtkmm, pangomm and glibmm for instructions on how to build gtkmm on Windows.
