in thread problem installing PLJava on Windows Vista

I don't get these warnings: 
PLJava.c: In function `main':
PLJava.c:173: warning: control reaches end of non-void function
PLJava.c:173:13: warning: no newline at end of file

Do you have a 'main' function in PLJava.c ? Where on earth did it come from ?

PLJava.c is a file that shipped with the PLJava-0.04 source. My copy of it definitely has no function named 'main', and there is definitely a newline at the end of the file. If we get those 2 things sorted out it might build. You can see what PLJava.c should look like at http://cpansearch.perl.org/src/GMPASSOS/PLJava-0.04/PLJava.c.

Rob

    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

      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:
