I hit segv's early on. A patched .24 version works but as Bazsi and I have found, Sun is playing games again. Grab and install this package scsh-0.5.1.tar.gz before compileing libol. Libol uses scheme shell to do some what looks like to be object oriented extentions to the C langugage :) ** Looks like you did this; make sure its in your path and that libol knows about it. # head /usr/local/bin/make_class #! /usr/local/bin/scsh \ -e main -s I also got the same message because it wasn't able to find scsh. Bazsi sent a message out, which I confirmed, that argp being sent back from the afdoor fucntion is NULL. I've been scouring the 'net for syslog_door stuff. I haven't come up with anything reasonable yet. coquille{root}242: gdb ./syslog-ng GNU gdb 4.17 Copyright 1998 Free Software Foundation, Inc.
