I've been trying to get the CP optimizer (12.8.0) to work in OSX in a java project.  It seems like the system fails to find the correct dynamic libraries .I've tried a lot of things, like setting -Djava.library.path, DYLD_LIBRARY_PATH og LP_LIBRARY_PATH.

I tried using the provided makefile for creating and running the Sports example, but this gives the same error:

Nogen som har haft success med at køre CP (IBM ILOG) optimizeren i OSX?   Jeg syntes jeg har fulgt vejledningen med at specificere mange parametre. Jeg kan kun få det at  compile  ikke køre:

Any ideas?

And what happens if you try to run an example with oplrun ?

Hi Alex,

The "oplrun" command works fine, it shows me the usage help page. It also works when runnning it with a mod and dat file.

Hello,
Do the distributed java examples work when you go in 
CPLEX_Studio128/cpoptimizer/examples/x86-64_osx/static_pic
And run 'make execute_java' ?

You also could have a look at:

Hi Philippe

That is exactly what I was running (see the first post).

Hi Alex and Philippe

I found the source of my problem. It turns out that I had been using a "wrong" JAVA_HOME path.

Using the following value to set the environment variable helps!

export JAVA_HOME=$(/usr/libexec/java_home) 

This is probably only useful for osx users.

I can now run the provided examples, and my own solution.

Thanks
