.codenameone/cef/lib/linux64/libjawt.so is missing

[jsfan3]

When I try to play a video in the Simulator, I get this error:

java.lang.UnsatisfiedLinkError: /home/francesco/.codenameone/cef/lib/linux64/libjcef.so: libjawt.so: impossibile aprire il file oggetto condiviso: File o directory non esistente
	at java.lang.ClassLoader$NativeLibrary.load(Native Method)

Translated:

java.lang.UnsatisfiedLinkError: /home/francesco/.codenameone/cef/lib/linux64/libjcef.so: libjawt.so: unable to open shared object file: Non-existing file or directory

You can probably workaround this temporarily by removing the ~/.codenameone/cef directory and falling back to the JavaFX backend or by updating the system lib path to include a path to libjawt.so

This looks like this known issue:

On Ubuntu 20, and some other versions of Linux, it has been reported that, when running the Codename One simulator with CEF installed, you get UnsatisfiedLinkException mentioning that libjcef.so could not find libjawt.so. This is caused because the lib directory of the JDK is not in the LD_LIBRARY_PATH. You an work around this problem by adding it. E.g.

export LD_LIBRARY_PATH=$JAVA_HOME/lib/amd64

I confirm that removing the ~/.codenameone/cef directory and falling back to the JavaFX workarounded this issue.

I would recommend the other workaround, we are moving to CEF for many things. E.g. The CSS compiler now requires CEF for some things.

@shannah I confirm that export LD_LIBRARY_PATH=$JAVA_HOME/lib/amd64 solved my issue but only after enabling 3D hardware acceleration (without 3D acceleration it crashes).

This issue is resolved in Maven, as the maven plugin will automatically add the LD_LIBRARY_PATH to the environment.
