UnsatisfiedLinkError - x86_64 GNU/Linux
entarch1980 opened this issue · 6 comments
Hi,
I have been trying to use jnativehook 2.1.0 on AWS EC2 running x86_64 GNU/Linux. I have checked libJNativeHook-2.1.0.x86_64.so is there in /tmp folder. I have also installed libxkbcommon-x11. Still I am getting this error. I also tried overriding the java.io.tmpdir, but still the same
Caused by: java.lang.UnsatisfiedLinkError: /tmp/libJNativeHook-2.1.0.x86_64.so: libXt.so.6: cannot open shared object file: No such file or directory

After install libXt.so, now I am getting the below error on application startup

The crash happened outside the Java Virtual Machine in native code.

Grab that log file hs_err_pid7013.log file.
I am not sure if this is going to work in AWS-EC2, I presume you are using VNC or X11-forwarding or something like that?
Ubuntu Dependencies:
sudo apt-get install \
libx11-dev:amd64 \
libxtst-dev:amd64 \
libxt-dev:amd64 \
libxinerama-dev:amd64 \
libx11-xcb-dev:amd64 \
libxkbcommon-dev:amd64 \
libxkbcommon-x11-dev:amd64 \
libxkbfile-dev:amd64
EC2 is having centos as underlying OS..I am not using VNC...even though X11-forwarding is turned on..I actually don't want to use any display.. I will be attaching the hs_err_pid7013.log in a bit
I actually don't want to use any display
This library has to run under X11. There is no headless / cli only mode available. If it were to run in that environment it would require root and probably a totally separate service.
