# Build register.c, which contains a function register_all_protocols()
# that calls the register routines for all protocols and a function
# register_all_protocol_handoffs() that calls the handoff registration
# routines for all protocols.
#
# We do this by scanning through sources.  If that turns out to be too slow,
# maybe we could just require every .o file to have an register routine
# of a given name (packet-aarp.o -> proto_register_aarp, etc.).
#
# Formatting conventions:  The name of the proto_register_* routines an
# proto_reg_handoff_* routines must start in column zero, or must be
# preceded only by "void " starting in column zero, and must not be
# inside #if.
#
# DISSECTOR_SRC is assumed to have all the files that need to be scanned.
#
# For some unknown reason, having a big "for" loop in the Makefile
# to scan all the files doesn't work with some "make"s; they seem to
# pass only the first few names in the list to the shell, for some
# reason.
#
# Therefore, we have a script to generate the register.c file.
# The shell script runs slowly, as multiple greps and seds are run
# for each input file; this is especially slow on Windows.  Therefore,
# if Python is present (as indicated by PYTHON being defined), we run
# a faster Python script to do that work instead.
#
# The first argument is the directory in which the source files live.
# The second argument is "dissectors", to indicate that we should build
# a register.c file for libethereal.
# All subsequent arguments are the files to scan.

#
# Currently register.c can be included in the distribution because
# we always build all protocol dissectors. We used to have to check
# whether or not to build the snmp dissector. If we again need to
# variably build something, making register.c non-portable, uncomment
# the dist-hook line below.
#
# Oh, yuk.  We don't want to include "register.c" in the distribution, as
# its contents depend on the configuration, and therefore we want it
# to be built when the first "make" is done; however, Automake insists
# on putting *all* source into the distribution.
#
# We work around this by having a "dist-hook" rule that deletes
# "register.c", so that "dist" won't pick it up.
#
#dist-hook:
#	@rm -f $(distdir)/register.c
