# Makefile.node.defs: Makefile for building and bundling your own Node.js.
#
# NOTE: This makefile comes from the "eng" repo. It's designed to be dropped
# into other repos as-is without requiring any modifications. If you find
# yourself changing this file, you should instead update the original copy in
# eng.git and then update your repo to use the new version.
#
#
# This Makefile facilitates building and bundling your own copy of Node.js in
# your repo. All it does is define variables for node, node-waf, and npm for
# you to use elsewhere in your Makefile and rules to build these tools when
# needed.
#
# To use this facility, include "Makefile.node.defs", use the variables as
# described below to define targets, and then include "Makefile.node.targ".
#
# There are two use cases addressed here:
#
# (1) Invoking node, node-waf, or npm as part of the build process, as in "npm
# install" and "node-waf configure build". To facilitate this, this
# Makefile defines Make variables NODE, NODE_WAF, and NPM that you can use
# to invoke these commands during the build process. You MUST NOT assume
# that these variables just evaluate to the filenames themselves, as they
# may have environment variable definitions and other things that prevent
# you from using them directly as a filename. If you want that, see (2).
#
# Wherever you use one of these variables, you MUST include a dependency on
# the corresponding *_EXEC variable as well, like so:
#
# node_modules/restify: deps/restify $(NPM_EXEC)
# $(NPM) install deps/restify
#
# or better, use an order-only dependency to avoid spurious rebuilds:
#
# node_modules/restify: deps/restify | $(NPM_EXEC)
# $(NPM) install deps/restify
#
# Otherwise, the underlying file will not get built. We don't
# automatically build them as part of "all" because that approach is
# brittle.
#
# (2) Specifying paths for invoking node, node-waf, or npm at RUNTIME, as in
# specifying the path to node used for the start method of your service's
# SMF manifest. For this, this Makefile defines variables NODE_EXEC,
# NODE_WAF_EXEC, and NPM_EXEC, which represent the relative paths of these
# files from the root of the workspace. You MUST NOT use these variables
# to invoke these commands during the build process. See (1) instead.
#
# However, in order to work at runtime, you must build the tool as well.
# That is, if you use NODE_EXEC to specify the path to node, you must
# depend on NODE_EXEC somewhere. This usually happens anyway because you
# usually need them during the build process too, but if you don't then
# you need to explicitly add NODE_EXEC (or whichever) to your "all"
# target.
#
# When including this Makefile, you MAY also specify:
#
# BUILD top-level directory for built binaries
# (default: "build")
#
# NODE_INSTALL where node should install its built items
# (default: "$BUILD/node")
#
# NODE_CONFIG_FLAGS extra flags to pass to Node's "configure"
# (default: "--with-dtrace" on SmartOS; empty
# otherwise.)
#
