# mkmakemod.sh: generate Makefile.in files for module building
|
|
#
|
|
# Options:
|
|
# -m = file is already generated; only build the second stage
|
|
# -i = do not build second stage
|
|
#
|
|
# Args:
|
|
# $1 = subdirectory to look in, relative to $top_srcdir
|
|
# $2 = final output filename, within the $1 directory
|
|
#
|
|
# This script must be run from the top-level build directory, and $top_srcdir
|
|
# must be set correctly in the environment.
|
|
#
|
|
# This looks in $1, and uses all the *.mdd files there. Each .mdd file
|
|
# defines one module. The .mdd file is actually a shell script, which will
|
|
# be sourced. It may define the following shell variables:
|
|
#
|
|
# name name of this module
|
|
# moddeps modules on which this module depends (default none)
|
|
# nozshdep non-empty indicates no dependence on the `zsh/main' pseudo-module
|
|
# alwayslink if non-empty, always link the module into the executable
|
|
# autofeatures features defined by the module, for autoloading
|
|
# autofeatures_emu As autofeatures, but for non-zsh emulation modes
|
|
# objects .o files making up this module (*must* be defined)
|
|
# proto .syms files for this module (default generated from $objects)
|
|
# headers extra headers for this module (default none)
|
|
# hdrdeps extra headers on which the .mdh depends (default none)
|
|
# otherincs extra headers that are included indirectly (default none)
|
|
#
|
|
# The .mdd file may also include a Makefile.in fragment between lines
|
|
# `:<<\Make' and `Make' -- this will be copied into Makemod.in.
|
|
#
|
|
# The resulting Makemod.in knows how to build each module that is defined.
|
|
# For each module it also knows how to build a .mdh file. Each source file
|
|
# should #include the .mdh file for the module it is a part of. The .mdh
|
|
# file #includes the .mdh files for any module dependencies, then each of
|
|
# $headers, and then each .epro (for global declarations). It will
|
|
# be recreated if any of the dependency .mdh files changes, or if any of
|
|
# $headers or $hdrdeps changes. When anything depends on it, all the .epros
|
|
# and $otherincs will be made up to date, but the .mdh file won't actually
|
|
# be rebuilt if those files change.
|
|
#
|
|
# The order of sections of the output file is thus:
|
|
# simple generated macros
|
|
# macros generated from *.mdd
|
|
# included Makemod.in.in
|
|
# rules generated from *.mdd
|
|
# The order dependencies are basically that the generated macros are required
|
|
# in Makemod.in.in, but some of the macros that it creates are needed in the
|
|
# later rules.
|
