# Makefile to create the Lustre/LNet plugins for Wireshark.
# It is intended to be used by script `wsbuild´ that will buil
# a RPM for wireshark and a separate RPM for the Lustre/LNet plugins.
#
# All configuration should be performed with help of shell script
# `wsconfigs.sh' (see can-edit sections).
#
# When using as a stand-alone makefile, set the macros WS_HOME,
# PLUGIN_DIR and PLUGIN_COMPILE_FLAGS to the values associated with
# your wireshark installation.
# Alternatively modify `wsconfigs.sh´ accordingly to your wireshar
# installation, source wsconfigs.sh and build with help of:
#
#      make -e -f Makefile
#


# Installation directory of the Wireshark source code
#    Note: Leave the macro undefined when using the wsbuild script.
#
# WS_HOME =
WS_HOME = 

# Installation directory for the (compiled) Wireshark plugins
#    Change the value of the following macro to the installation directory
#    of the Wireshark plugins for your installation 
#
#    Note: When using the cbuild script leave the macro undefined
#    (default: /usr/lib/wireshark/plugins/$(WS_VERSION))
#
#    For non-root and  non-rpmbuilds you might want to set the value to ${HOME}/.wireshark/plugins
