Hard to envisage that would work anywhere. Adding the following at the very top of PerlNatives.xs fixes this problem: #include "EXTERN.h" #include "perl.h" #include "XSUB.h" and Inline-Java-0.52 (along with PerlNatives) then builds fine for me. How about for you selva ? Annoyingly, the PerlNatives test script bails out before running any of the 5 scheduled tests. The error message I'm getting is: t/02_perl_natives.t .. Unexpected exception of type 'java.lang.UnsatisfiedLinkError': RegisterMethod at C:\_32\comp\Inline-Java-0.52\blib\lib/Inline/Java/Object.pm line 49 Something to look at tomorrow .... thanks Nicholas.
