Common Failure Messages - MATLAB & Simulink

Exception in thread "main" java.lang.UnsatisfiedLinkError: Failed to find the library mclmcrrt712.dll, required by MATLAB Compiler SDK, on java.library.path

Install the MATLAB^® Runtime or add it to the MATLAB path.

Failed to find the library <library_name>, required by MATLAB Compiler SDK, on java.library.path.

This error commonly occurs on Linux^® or Mac systems if the LD_LIBRARY_PATH or DYLD_LIBRARY_PATH variable is not set. For more information, see Set MATLAB Runtime Library Paths for Deployment.

javac is not recognized as an internal or external command, operable program or batch file.

This is a common error when the javac executable (javac.exe), installed with Java, is not on your system PATH.

Edit your system environment variables and add your Java installation folder to the PATH variable.

Java packages generated using the LibraryCompiler app that serialize and deserialize MathWorks Java classes will throw an exception or hang when using serialization filtering in Java 8.

MathWorks^® Java^® classes need to be on the filter pattern list of the serialization filtering feature of Java 8 so that they can be passed to the method java.io.ObjectInputStream.filterCheck(). This will prevent an application using the Java package from throwing an exception or from hanging. To fix the issue, set the following system properties at the command line:

jdk.serialFilter=com.mathworks.** 
sun.rmi.registry.registryFilter=com.mathworks.**
