OpenJDK missing libawt_xawt.so #19

Open DuncanLithgow opened 1 year ago

DuncanLithgow commented 1 year ago

I'm not sure who should handle this or help with this. But I can't work it out. I see nowhere a way to install missing elements to OpenJDK.

I'm running Fedora GNU/Linux 37 and have installed OpenJDK JRE and JDK

My understanding is that libawt_xawt.so is needed for drawing gui windows, so of course this graphical program won't start.

I have no idea. Can you try to run the jar file from this website?https://intofuture.org/energy2d.html

Hi Charlie. I'm using the file from that site.

Here's some more info about what is happening in Fedora 38 with OpenJDK 17

It seems it can't fnd/access /usr/lib/jvm/java-17-openjdk-17.0.8.0.7-1.fc38.x86_64/lib/libawt_xawt.so

Is there any useful information there?

Could something here be the problem? https://www.tutorialspoint.com/how-to-handle-java-lang-unsatisfiedlinkerror-in-java

"UnsatisfiedLinkError is caused by a number of factors, such as missing native libraries or library paths configured incorrectly, outdated library versions or dependencies that the native code requires."

I currently do not have a Linux machine for testing. I am still hoping that we will eventually convert this to a Web app instead of Java, which is old.

If you want to make energy2d windows/linux cross platform you could run an Ubuntu USB persistent live environment as described here https://itsfoss.com/ubuntu-persistent-live-usb/
