# Build plugin.c, which contains the plugin_version[] and plugin_release[]
|
|
# string, and a function plugin_register() that calls the register routines
|
|
# for all codecs.
|
|
#
|
|
# We do this by scanning 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 codec_register_* routines must
|
|
# start in column zero, or must be preceded only by "void " starting in
|
|
# column zero, and must not be inside #if.
|
|
#
|
|
# REGISTER_SRC_FILES 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 use a script to generate the register.c file.
|
|
# The first argument is the directory in which the source files live.
|
|
# The second argument is "plugin_codec", to indicate that we should build
|
|
# a plugin.c file for a codec plugin.
|
|
# All subsequent arguments are the files to scan.
