Incompatible libOgreMainStatic.a

[cfoch]

Hello,
I have installed Ogre3D for Android following this guide

Now I want to build a simple file containing only ¨int main(int argc, char **argv) { return 0;}¨, but I get errors when compiling.

THE ERROR...

You are probably trying to target an arch for which you haven't built those libs. For example, you are using ndk-build on an android project, and in your Application.mk you are targeting all three of armeabi, armeabi-v7a and x86 while you have only built static libs for armeabi-v7a.
