[kepler-users] Kepler 2.3 and MATLAB

[Wade Sheldon]

Thanks, Christopher. I had already perused the mailing list archives via Google and just saw references to the same issue without solutions. I confirmed that the JVM bit width is 32 (Java version 1.6.0_20).

I set up a simpler workflow with just a SDF director, MatalbExpression actor and text display actor, and configured the expression: "rand(100,1);", but I got the same error. Here's the trace from the first time it was invoked, which yielded a little more info as you indicated, specifically "C:\Program Files\Kepler-2.3\common-2.3.0\lib\ptolemy\matlab\ptmatlab.dll: The operating system cannot run %1". Hope that points to a specific issue.

Thanks.

complete stack dump:
ptolemy.kernel.util.IllegalActionException: There was a problem invoking the Ptolemy II Matlab interface.
The interface has been tested under Linux, Mac OS X, and Windows.
The interface requires that Matlab be installed on the local machine and that the ptmatlab shared library available.
* Under Linux, you must have the LD_LIBRARY_PATH environment variable set to include the directories that contain libmx.so and libptmatlab.so.
* Under Mac OS X, you must have the DYLD_LIBRARY_PATH environment variable set to include the directories that contain libmx.dylib and libptmatlab.jnilib.
* Under Windows, you must have your PATH set to include the Matlab bin/win32 or equivalent directory so that libmex.dll is found and the directory that contains libptmatlab.dll. In addition, if you are running under Windows from the Cygwin bash prompt, then you must start Vergil with the -jni argument: $PTII/bin/vergil -jni. For details, see $PTII/jni/package.html.
Refer to $PTII/ptolemy/matlab/makefile for more information.
