Installing in Raspberry Pi. How?

Hi guys.

I’m trying to install Urho3D on RPi 3 (GPU=768 MB).

First, I tried the general linux method described here: … d-in-Linux
But it gave error during the final make process:

[ 56%] Building CXX object Source/Urho3D/CMakeFiles/Urho3D.dir/Graphics/Skybox.cpp.o [ 57%] Building CXX object Source/Urho3D/CMakeFiles/Urho3D.dir/Graphics/Graphics.cpp.o In file included from /root/Urho3D/Source/Urho3D/Graphics/../Graphics/GraphicsImpl.h:29:0, from /root/Urho3D/Source/Urho3D/Graphics/Graphics.cpp:34: /root/Urho3D/Source/Urho3D/Graphics/../Graphics/OpenGL/OGLGraphicsImpl.h:36:23: fatal error: GLES2/gl2.h: No such file or directory #include <GLES2/gl2.h> ^ compilation terminated.

Someone suggested to run instead of cmake . in the cmake process.

But when I run . it gives the following:

So, what shall I do !?
How can I install Urho3D in RPi !!?

Ok. I did it.
I had to define a path!
I used the following command:

I hope the ongoing make process doesn’t give any more errors.
