UnsatisfiedLinkError: Can't load library: .../libgluegen_rt.dylib #30

If you experienced UnsatisfiedLinkError on other JOGL library than Gluegen see : https://github.com/jzy3d/jogl/issues/29

Gluegen native library loading error may happen for several reasons.

Hardware not supported

You are running JOGL on a hardware that is not supported. Is this is macOS M1, use this release instead.

Inappropriate permissions defined

There are wrongly defined permission schemes preventing the libraries to be loaded. Using -Djogamp.debug.IOUtil VM argument allows showing such issue in console : IOUtil.testDirExec: </tmp/jogamp_exe_tst6252795205786161366.sh>: Caught IOException: Cannot run program "/tmp/jogamp_exe_tst6252795205786161366.sh": error=13, Permission denied

A developer reported

The DEB packager that I used did NOT set the correct permissions on the jre/lib/jspanwhelper. After installation the permissions were 644 (RW,R,R). A chmod 755 /jre/lib/jspanwhelper fixed the JOGL native lib loading issue completely.

How to debug further

If you did not find a solution above, try enabling more logs by using the JVM arguments -Djogamp.debug.JarUtil -Djogamp.debug.JNILibLoader -Djogamp.debug.IOUtil. They will print lot of information on the loading process.
