# Sample shell script for running Q2Java using an older Blackdown JVM
#

JAVA_HOME="/usr/local/java/jdk117_v1a"
QUAKE2_HOME="/usr/local/games/quake2"
#QUAKE2_PARAMS="+set vid_ref softx"

# Preload JVM DLL, call quake2 next.
#
# Quake2 is linked against libdl.so,
#  but not linked against libjava.so.
#
# It does use dlopen("gamei386.so"),
#  and gamei386.so is linked
#  against libjava.so.
#
# gamei386.so does invocation
#  of a JVM, Quake2 is not Java aware.
#
# Without the preload, this fails
#  on every RH 5.x and Debian 2.x tried so far.
