I built a libGDX application that runs well on my PC desktop but when I try to run it on my Ubuntu server, it raises the following error:
"LwjglApplication: Couldn't initialize audio, disabling audio java.lang.UnsatisfiedLinkError: /tmp/libgdxroot/31ce78a2/liblwjgl64.so: /usr/lib/jvm/java-7-openjdk-amd64/jre/bin/../lib/amd64/libjawt.so: symbol awt_Unlock, version SUNWprivate_1.1 not defined in file libmawt.so with link time reference".
I know this is because my server is running in non-GUI mode. But how can I run my libGDX app in this environment?. I've heard about "libGDX headless backend". But I don't know how to use it. Thanks in advance.
Best How To :
I've answer my self this question for anyone who's looking for this. First, added these two libraries in the build.gradle file:
Then, I've started my libGDX as following:
MockGraphics mockGraphics = new MockGraphics();
Gdx.graphics = mockGraphics;
HeadlessNet headlessNet = new HeadlessNet();
Gdx.net = headlessNet;
HeadlessFiles headlessFiles = new HeadlessFiles();
Gdx.files = headlessFiles;
Gdx.gl = mock(GL20.class);
HeadlessApplicationConfiguration config = new HeadlessApplicationConfiguration();
ApplicationListener myGdxGame = EntryPoint.getHeadlessMyGdxGame(config);
and EntryPoint.getHeadlessMyGdxGame return an inherited of HeadlessApplication
