1. Compilation problems

1.1. Error when compiling MATLAB (Windows only)

Under Windows, if the BCVTB is compiled using the Microsoft compiler, then the MATLAB libraries also need to be compiled with the Microsoft compiler. If, however, the gcc compiler has been used when compiling the BCVTB, then the following compilation error may be obtained when compiling the MATLAB libraries:

Writing library for establishBSDSocket.mexw32
c:\docume~1\mwetter\locals~1\temp\mex_ae679\simulinksocket.obj .text: undefined reference to '_establishclientsocket'
c:\docume~1\mwetter\locals~1\temp\mex_ae679\simulinksocket.obj .text: undefined reference to '_exchangewithsocket'
c:\docume~1\mwetter\locals~1\temp\mex_ae679\simulinksocket.obj .text: undefined reference to '_closeipc'

To fix this problem, open Matlab, run

mex -setup

and select the Microsoft Visual C++ compiler from the menu. This need to be done only once as it updates your Matlab settings.

2. Runtime problems

The following steps typically help analyzing problems if a simulation program does not work as expected.

2.1. Check program output

By default, the Simulation actor in Ptolemy writes a copy of the console output of the simulation program to a file called simulation.log. This file can typically be found in the directory from which the simulation program has been started.

2.2. Check log files

If something goes wrong during the simulation, check the files simulation.log, utilSocket.log and utilClient.log. They contain log messages that may indicate the cause of the problem. If these files do not exist, go to the directory bcvtb/lib, open the file defines.h and add the line

#define NDEBUG

Then, from the directory bcvtb/lib/util compile the libraries using

ant clean all

and rerun the simulation. Now the log files should be written to the directory from which you started the BCVTB.

2.3. Memory problem

If the following error occurs:

java.lang.OutOfMemoryError: Java heap space

then increase the Java heap space by running vergil with the command

java -Xmx1024m ptolemy.vergil.VergilApplication system.xml

The argument -Xmx1024m declares how much memory is allocated. The default for Java is -Xmx128m

2.4. Wrong Java version

The following error occurs if a too old Java version is used:

java.lang.UnsupportedClassVersionError: Bad version number in .class file

To fix this problem, update your Java.
