in thread problem installing PLJava on Windows Vista

Ough, yeah, I put that there 'cause when I didn't it complained that it couldn't find a main (I think) ...

I took the main() out and ran it through and now the output ends with

+xt'

    We need to make sure there's a newline at the end of PLJava.c, too.
    And we need to get rid of that cygwin stuff - we're using MinGW, not cygwin. Whatever it is that you've done to introduce Cygwin into the mix needs to be undone - if you haven't done anything to cause that, then it must just be that Cygwin needs to be removed from your path.

    Once that's done, start from scratch with a fresh install, and see how far that gets us. All we need for the 'dmake' phase to work is a path that includes mingw/bin, perl/bin, and the directory that contains 'dmake.exe' - and we also need those 3 Java environment variables set (which you've apparently already done).

    Cheers,
    Rob

      Like I said, I tried a bunch of different stuff before posting here... This is what it looks like without Cygwin in the path.

      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

        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
