Could NOT find compatible Urho3D library

Discussions Support
#1

I’m trying to compile android game.
I’ve compiled Urho3d via cmake and make install it
Then I created a dummy project from this article

And…

mkdir android
./cmake_android ./android -DANDROID_NATIVE_API_LEVEL=android-14

CMake Error at CMake/Modules/FindUrho3D.cmake:346 (message):
Could NOT find compatible Urho3D library in Urho3D SDK installation or
build tree. Use URHO3D_HOME environment variable or build option to
specify the location of the non-default SDK installation or build tree.
For Android platform, double check if you have specified to use the same
ANDROID_ABI as the Urho3D library in the build tree or SDK.
Call Stack (most recent call first):

What did I do wrong?

As I understand, you must set environment variable URHO3D_HOME which contains path to your Urho3D installation (directory, generated by make install).

#3 
echo $URHO3D_HOME

But you was partially right I’ve closed terminal window and my export URHO3D_HOME result gone. I’ve made export again and now it shows me more errors like

/home/me/Android/Sdk/ndk-bundle13/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64/lib/gcc/arm-linux-androideabi/4.9.x/…/…/…/…/arm-linux-androideabi/bin/ld:

#5

The linker error was “incompatible target”

It means your Urho3D lib was not built for the same target platform or architecture as your app.

#6

Do you mean I have compiled urho without android target?

#7

Use the “file libUrho3D.a” command to verify.

#8

From which directory? URHO3D_HOME/lib?

#9

Yes. And the fact it is in “lib” folder already gives a tell tale sign that it was not built for Android platform.

#10

I just ran ccmake and discovered no android settings at all. I cloned latest version of urho from github (master). Do I need to clone a specific branch?
