Question

I am using Eclipse CDT, with MinGW and under Windows XP, to developp a little C program exporting itself as a JNI-compliant DLL.

Debugging the program from the Java calls is not easy, and thus I added a “Debug” configuration to my project and a main method that tests some functions.

When I launch the debug, i get this weird Java error :

An internal error occurred during: "Launching NuanceWrapper.exe".
java.lang.IllegalArgumentException

It seems very much like it is an internal Eclipse problem. I got the stacktrace of the exception in the .log file of the .metadata folder :

!ENTRY org.eclipse.core.jobs 4 2 2011-02-04 14:08:31.531
!MESSAGE An internal error occurred during: "Launching Wrapper.exe".

Any idea what could be the problem ? I really need this debug functionality in order to understand what is wrong in my code.

Thank you for your answers.

I looked at the source code of the different files of your stack trace, and it seems to be a problem with your CDT project’s configuration. You should check the settings here and try to change them.

One of the CDT build variables seems to be wrong. In LaunchUtils.java, line 390, var.getStringValue() is causing the issue because in this variable (var), which contains a name and an associated value, the value is null.

Hope this helps.
