I am new to Linux and I am having trouble getting a lwjgl app to run. I get an unsatisfied link error. Here is the error:
(cborders)>Run.sh
Exception in thread "main" java.lang.UnsatisfiedLinkError: /usr/lib/liblwjgl.so: /usr/lib/liblwjgl.so: cannot open shared object file: No such file or directory

at elderGods.ElderGods.main(ElderGods.java:11)
here is the script that I am using to run:
#!/bin/bash
java -Djava.library.path=/usr/lib/ -cp .:ElderGods.jar:lwjgl.jar:lwjgl_util.jar:lwjgl_devil.jar elderGods.ElderGods
and here is proof that the libs are where I think they are:
(cborders)>whereis liblwjgl.so
liblwjgl: /usr/lib/liblwjgl.so
What am I doing wrong here?
first of all you really shouldn't install lwjgl into the system path - lwjgl is designed to be run from a local dir.
That said, are the rights on the file correct? - specifically the x bit has to be set for the relevant user/group
I put the libs in the system path when it didn't work from the project directory! Ok, so I moved them back to the project directory and checked the permissions on the libraries
(cborders)>ls -l *.so
-rwxr-xr-x 1 cborders cborders 728425 Aug 18 15:56 libIL.so
-rwxr-xr-x 1 cborders cborders 171001 Aug 18 15:56 libILU.so
-rwxr-xr-x 1 cborders cborders 42227 Aug 18 15:56 libILUT.so
-rwxr-xr-x 1 cborders cborders 37476 Aug 18 15:56 liblwjgl-devil.so
-rwxr-xr-x 1 cborders cborders 214836 Aug 18 15:56 liblwjgl.so
and modified the script to be:
#!/bin/bash
java -Djava.library.path=./ -cp .:ElderGods.jar:lwjgl.jar:lwjgl_util.jar:lwjgl_devil.jar elderGods.ElderGods
and then
#!/bin/bash
java -Djava.library.path=/home/cborders/Desktop/ElderGods -cp .:ElderGods.jar:lwjgl.jar:lwjgl_util.jar:lwjgl_devil.jar elderGods.ElderGods
and both times I get:
(cborders)>Run.sh
Exception in thread "main" java.lang.UnsatisfiedLinkError: /home/cborders/Desktop/ElderGods/liblwjgl.so: /home/cborders/Desktop/ElderGods/liblwjgl.so: cannot open shared object file: No such file or directory
