dmake:  Error code 129, while making 'PLJava.dll'

Update: Eugh, well, there's the problem, then. I updated MinGW to include g++ and now I get what you had before where dmake runs with no errors but dmake test fails:

C:\Users\Name\Documents\Downloads\PLJava-0.04>dmake test
C:\PROGRA~1\Java\jdk1.5.0\bin\java test
PLJava - Native code library failed to load. See the chapter on Dynami
+c Linking
Problems in the SWIG Java documentation for help.
java.lang.UnsatisfiedLinkError: PLJava_start
dmake:  Error code 129, while making 'test'
[download]

Well ... I guess that's progress, at least :-)
Incidentally (for future reference), assuming you have ActivePerl, the easiest way to install both dmake and MinGW is to simply ppm install MinGW
That will give you all you need.

The 'dmake test' error has me baffled. Afaict, 'PLJava_start' is simply a function in PLJava.c, and I don't understand what java.lang.UnsatisfiedLinkError: PLJava_start is supposed to tell me.

As recommended by the test output, I've read "the Chapter on Dynamic Linking" in "the SWIG Java documentation for help" ... but it didn't. That documentation can be viewed online. If anyone has ideas on what to do at this point, then please share. (I don't mind trying to solve a good puzzle, but I'm not a java person at all.)

Cheers,
Rob

Same here. I'm a lot more up on Java than I am on Perl, but not to the point that I have any clue what to do here. Maybe I should take this to a Java forum at this point.

Thanks for the help anyway, though.
