Hi, I installed JLink on my Slackware 2.2.14 system using jdk 1.2.2
exactly as
explained in the manual (compiling and copying library, copying
JLink.jar etc.),
but when I try to InstallJava[], (after <<JLink`) I get the following
message on 
my stderr:

---stderr------------------------------------------------------------------------------

SIGSEGV   11*  segmentation violation

    si_signo [11]: SIGSEGV   11*  segmentation violation

    si_errno [0]: Success

    si_code [0]: SI_USER [pid: 0, uid: 0]

I can't understand this. What's happening?
