I encountered the following error when running the example in the package

javac -d . -classpath ../../lib/gurobi.jar:. ../java/Mip1.java
java -classpath ../../lib/gurobi.jar:.: Mip1
Exception in thread "main" java.lang.UnsatisfiedLinkError: no GurobiJni91 in java.library.path: [/usr/java/packages/lib, /usr/lib/x86_64-linux-gnu/jni, /lib/x86_64-linux-gnu, /usr/lib/x86_64-linux-gnu, /usr/lib/jni, /lib, /usr/lib]

  Hi,

  Could you try setting the \(\texttt{LD_LIBRARY_PATH}\) environment variable as described in the installation guide?

  Best regards,
