Hi,

I have installed CPLEX on my Mac, and am calling CPLEX from the Terminal. According to the "Quick Start to IBM ILOG Optimization products" I am supposed to call ./cplex from the folder cplex_dir/bin/machine_dir. when I reach cplex_dir/bin/, I can choose from 2 options: x86_darwin8_gcc4.0/, or x86-64_darwin8_gcc4.0/, depending on whether my machine is 32 or 64 bit. To the best of my knowledge, my machine is 64 bit (Mac OS X 10.5.8, 2.26 GHz Intel Core 2 Duo). I have 2 questions:

• I have observed that ./cplex can be invoked from either folder (though I have not tried to run anything on either folder, I do not know how to do that yet). How come that happens?

• What's more weird (and possibly an indicator of a problem), when I call CPLEX from Eclipse, and specify x86-64_darwin8_gcc4.0/ as the native library location for cplex.jar, it gives me errors, whereas it seems to behave properly when I specify x86_darwin8_gcc4.0/ as the native library folder. But my machine is 64 bits! What's going on??

Being able to execute both binaries is not a problem. I guess your system can execute 32bit and 64bit binaries as well. Nevertheless, you should use the binary that matches your system, i.e. the 64bit binary.

Concerning the Java problem: Is your JVM a 32bit or 64bit binary? Does it run in 32bit or 64bit mode?
