If it's any consolation, my experience is that "tool integration" is almost impossible to achieve, in practice... Even if you get it working once, it will break when something changes... There is clearly a technical challenge here.

Hi folks, Thanks for all the advice last week, but I'm throwing in to towel unless someone has a radically new idea. I installed Matlab 2009a and that also failed to run the demo, but with a different error message: "Caused by: java.lang.UnsatisfiedLinkError: C:\Program Files\Kepler-2.3\common-2.3.0\lib\ptolemy\matlab\ptmatlab.dll: The specified procedure could not be found ...". I also tried R2007b (mentioned in help files) and had the same result as 2009a. So R2010a and R2011b error with "...The operating system cannot run %1" and R2007b and R2009a error with the above procedure call error, in case that's of any diagnostic value. I also installed Kepler on a different workstation run WinXP and had the same issues. To eliminate potential Java version issues, I wiped Kepler 2.3 and all the settings files, uninstalled an old version of the JDK I had on the box (1.6_18), installed a matching JDK to the Java libraries previously installed (1.6.0_31-b05) and reinstalled Kepler. Same result. I also added C:\Program Files\Kepler-2.3\common-2.3.0\lib\ptolemy\matlab to the path (based on Ptolemy Matlab troubleshooting guidelines) but that didn't help either. I then tried to follow the build instructions from the url Dan sent, spending most of the weekend setting up the software and source code and ironing out cygwin and mingw configurations and dependencies (the instructions on the reference page are out of date, and the mingw shell scripts described are not online and no mention is made of what libraries are needed for cygwin, so I had to guess and reinstall several times to get what was needed). After climbing down ever darker rabbit holes I managed to get a working build system set up, but then hit syntax errors with the .config files (apparently due to line terminator issues) and never could successfully build a dll. I concluded that this process is really untenable for someone not already set up to do Java development and use the entire Kepler build system, so at this point I rolled back my system and dumped the gig of software I spent all weekend messing with. So it was an informative, but ultimately futile, exercise. Thanks anyway. For my work it will be more productive to generate delimited files from Kepler and pick them up in Matlab, but I wanted to kick the tires and see if I could roll our Matlab code into native workflows. I'm about to rebuild that system using Win7/64 dual booting with Ubuntu, so I may try again if I feel adventurous. -Wade On 4/21/2012 4:48 PM, Daniel Crawl wrote:I can run the MatlabExpression workflow with Kepler 2.3 on WinXP SP3 (32bit) using Matlab 2009A and Java 1.6.0_31-b05. Your PATH looks ok (assuming you installed Matlab in C:\ and not the default C:\Program Files). It's possible that ptmatlab.dll is not compatible with newer versions of Matlab.

I also confirmed that the target "libmex.dll" is present in \bin\win32. I don't have cygwin installed to test Christopher's idea about building a new .dll, but I may play with that option over the weekend if I get ambitious. Based on Matt's comment that may ultimately prove necessary if the problem doesn't come down to path handling. Thanks for your input. -Wade On 4/20/2012 11:30 PM, Derik Barseghian wrote:Sorry this hasn't been easy, and no help from me yet -- I'm trying to get Matlab and a license for my 32bit XP box so that I can try to replicate, hopefully on Monday. It seems to me it should work on your XP box.

However this time I get an error related to running 32bit libraries on the system: C:\Program Files (x86)\Kepler-2.3\common-2.3.0\lib\ptolemy\matlab\ptmatlab.dll: Can't load IA 32-bit .dll on a AMD 64-bit platform (This is an Intel Core i7, not AMD cpu, BTW). Sigh. Harder than I'd hoped. Python and R work fine as on WinXP/32 - the problem is just related to the MatlabExpression actor, which is what I'm particularly interested in using. -Wade On 4/20/2012 10:41 PM, Wade Sheldon wrote:Also, I updated Java to the latest version (1.6.0_31-b05), uninstalled Kepler, and reinstalled from a full admin account. Same results. From what I can find on the web, that "The operating system cannot run %1" is a generic error that implies a path issue. Anything I can check regarding the Kepler classpath or libraries come to mind? Thanks again for your help. -Wade On 4/20/2012 10:02 PM, Wade Sheldon wrote: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".

Windows Server 2003 is fairly similar to XP. To determine the bit width of your JVM, start up Kepler, go to Tools -> check settings and look at the value of sun.arch.data.model = 32 When I start a dos shell (Start->Run->cmd), I can start matlab from the command line, which works for you.-- ______________________________________________________________________________ Wade M.
