MATLAB: Is it possible to run 64-bit MATLAB Builder for Java 1.0 (R2006b) components on a 32-bit Java Virtual Machine (JVM)

MATLAB Compiler SDK

When I attempt to run a MATLAB Builder for Java component created on a 64-bit machine on a 32-bit machine, I receive the following error message:
 Exception in thread "main" java.lang.UnsatisfiedLinkError: /opt/matlab/r2006b/bin/glnxa64/libnativemcl75.so: Can't load AMD 64-bit .so on a IA 32-bit platform

Best Answer

It is not possible to run 64-bit Builder for Java components on a 32-bit Java Virtual Machine (JVM). You will need to install a 64-bit JVM and then run the component under that.
Similarly, if you compiled the Java component with a 32-bit version of MATLAB and you plan to deploy it on a 64-bit operating system, you will need to at least install the 32-bit version of the MATLAB Compiler Runtime (MCR) and the JVM on the 64-bit machine.
For components built with MATLAB Builder for Java 2.0.1 (R2008a) onwards, please refer to the documentation at:
