Hello,
I just installed OpenFrameworks (from GIT), msys2 and QtCreator on Windows 10 x64. Windows10 updated to the newest build yesterday.
I followed: http://openframeworks.cc/setup/msys2/ and http://openframeworks.cc/setup/qtcreator
There is a mistake in the walkthrough as reported in an other message.
cd your_oF_directory/scripts/win_cb/msys2
./install_dependencies.sh`
But this I managed! 
I added both folders to the PATH of the system.
When I try to compile the example in the explanations in a MinGW32 I get a binary with loads of missing dll if I try to run it. Is this normal? Should I add more folders to the PATH of the system?
If I try to import the example using the wizard in QtCreator I get for all the GCC compilers I've tried that my system is not supported by the makefile.

Is there anything I missing here?
edit. I can start a new thread or you can move this if you think it deserves its own thread.
