Samples not working!

windows 10 + mingw
I compiled the project, and gen all the samples . But all the samples are just a black window after I run it.
some sample have sounds but not picture. How to fix it?

hard to help here with the little information.

First how did you build it?
What have you tried so far?
Are you using an IDE?
Did you look into the LOG Files? "C:\user\xxx\appdata\roaming\uhro3d\logs"
Did you using the actual github version of Urho3d?

Out of the belly you can try to build it with CMAKE-GUI and useing an IDE like Codeblocks or Visual Studio Community, maybe with this steps youll find the problem for your self.

I build it using cmake and mingw in terminals
no ide was used
using the master branch from github

cmake log, urho3d log? Without informations we cant help …

Did I miss some pre-requirements?
I only install DXSDK_Jun10

with mingw i would use OpenGL instead of DirectX, if you want DirectX use Visual Studio.or try another mingw version

Thanks a lot.
how to switch to Opengl? I notice that there are GLEW in thirdPartys. So can I just add some definition flag to switch to opengl? Or I have to install an opengl lib somehow

“-DURHO3D_OPENGL=1”

better clean your cmake files first

Old version of MinGW has bugs and writes incorrect shader cache, use latest Mingw from msys2 and remove broken shader cache https://github.com/urho3d/Urho3D/issues/2887
