Java Question

Gurobi UnsatisfiedLinkError

I am trying to install Gurobi under Academic Licence on Ubuntu 14.04. I have read the following post about the

UnsatisfiedLinkError
: stackoverflow.com/questions/.... But that didnt help me. I have extracted the zip in my
opt
folder. I have placed the licence file in
/opt/gurobi600/linux64/lib/gurobi.lic
.

I am trying to run the
Callback.java
example in Eclipse.

I have as Java VM argument:
-Djava.library.path=/opt/gurobi600/linux64/lib/
. I have as program argument:
/opt/gurobi600/linux64/examples/data/qafiro.lp
. The environment variable
LD_LIBRARY_PATH
is set on
/opt/gurobi600/linux64/lib/gurobi.lic


And I get the following stacktrace:

Exception in thread "main" java.lang.UnsatisfiedLinkError: /opt/gurobi600/linux64/lib/libGurobiJni60.so: libgurobi60.so: cannot open shared object file: No such file or directory

at main.Callback.main(Callback.java:135)


Any ideas?

Answer

It's all working properly now. I have removed the VM arguments in the run configurations menu, so that's all empty in Eclipse. I have changed the environment variables in Eclipse, they are now set to:

GUROBI_HOME      = /opt/gurobi600/linux64/
GRB_LICENCE_FILE = /opt/gurobi600/linux64/gurobi.lic
LD_LIBRARY_PATH  = /opt/gurobi600/linux64/lib/
PATH             = /opt/gurobi600/linux64/bin/
