Makefile

#
# Copyright (c) 2013 Juniper Networks, Inc. All rights reserved.
#

#
# This Makefile is used in a couple of contexts. One context is is obviously
# when you compile the vrouter module from the repository. Another context
# is when the sources get distributed as a package (for e.g.: dkms).
#
# In the second context, all sandesh source files needed for compilation will
# be under the sandesh/ directory.
#
# 'SANDESH_SRC_ROOT' points to where the make can find the sandesh files
# needed for compiling the module. If not set by command line, path will be
# relative.
#
# 'SANDESH_HEADER_PATH' will point to a place where we can find most of the
# header files needed for compilation of sandesh sources whereas
#
# 'SANDESH_EXTRA_HEADER_PATH' points to a place where additional header files
# can be found
#
# When the sources are ditributed, the sandesh compiler will not be present
# and hence the generated files (vr_types.c,h) will be packaged rather than
# the vr.sandesh file. Hence, the makefile in the sandesh directory is not
# packaged
#
# Since we want standalone make to work when the source is distributed, default
# values will point to the vrouter source root and when invoked from 'scons',
# the parent 'SConscript' will provide the paths through command line arguments
#
# Also, please note that if you add more source files, you will also need to
# add those files in RPM spec file and the rules file in the dkms package
#
