如何修复“无法为目标加载共享库'libgdx64.so'：Linux，64位”

Question

I am trying to use the headless LibGDX for unit testing, but when I run the test I get this error:

Couldn't load shared library 'libgdx64.so' for target: Linux, 64-bit

I read here that I need to add gdx-natives.jar . Is this correct, and where can I find this file?

Also, where in my project should I add the file?

Answer 1

I found the answer on this BitBucket repo . The README gives a nice explanation of how to implement this using Gradle.

Basically, you just add GdxTestRunner.java from that repo, and then add a @RunWith to each of your test files:

@RunWith(GdxTestRunner.class)
public class MyClassTest {
    ...
}

Then in your root level build.gradle file, add something like this to your core dependencies:

testCompile "com.badlogicgames.gdx:gdx-backend-headless:$gdxVersion"
testCompile "com.badlogicgames.gdx:gdx:$gdxVersion"
testCompile "com.badlogicgames.gdx:gdx-platform:$gdxVersion:natives-desktop"
testCompile "com.badlogicgames.gdx:gdx-box2d:$gdxVersion"
testCompile "com.badlogicgames.gdx:gdx-box2d-platform:$gdxVersion:natives-desktop"
testCompile "com.badlogicgames.gdx:gdx-bullet:$gdxVersion"
testCompile "com.badlogicgames.gdx:gdx-bullet-platform:$gdxVersion:natives-desktop"

Obviously the box2d and bullet dependencies are only necessary if you are using those libraries.

On the BitBucket repo README, the example includes both

testCompile "com.badlogicgames.gdx:gdx-backend-headless:$gdxVersion"

and

compile "com.badlogicgames.gdx:gdx-backend-headless:$gdxVersion"

I don't think it is necessary to include this for compile , and if I correctly understand how Gradle works, it will actually slow down your build.
