Makefile

+
+# Toplevel Makefile for Purr Data. Please note that at present this is just a
+# thin wrapper around l2ork_addons/tar_em_up.sh, the traditional Pd-l2ork
+# build script.
+
+# The Pd-l2ork build system is very arcane and intricate. Its main purpose is
+# putting together a staging area with a complete Pd-l2ork installation and
+# then building installers for the supported platforms from that, pulling
+# together a bunch of separate packages, each with their own build system.
+# Compiling sources is just one of the tasks that the builder does. Therefore
+# you'll notice that, unlike with other less complicated source packages,
+# `make` will rebuild lots of things even if you just finished another build.
+
+# The available build targets are:
+
+# all: produce a native installer for the host platform (equivalent to
+# `tar_em_up.sh -Tk`); note that in order to force a complete rebuild (like
+# what `tar_em_up.sh -T` does), you'll have to run `make clean` first
+
+# incremental: like `all`, but does an "incremental build" (equivalent to
+# `tar_em_up.sh -tk`), bypassing Gem which takes an eternity to compile; please
+# check the tar_em_up.sh script for details
+
+# light: like `incremental`, but does a light build (equivalent to
+# `tar_em_up.sh -tkl`) which only includes the most essential externals;
+# please check the tar_em_up.sh script for details
+
+# checkout: convenience target to check out all submodules in preparation for
+# a subsequent build (the `all`, `incremental` and `dist` targets also do this
+# automatically when needed)
+
+# clean: does something similar to what `tar_em_up.sh` does in order to start
+# from a clean slate, so that a subsequent build starts from scratch again
+
+# realclean: put the sources into pristine state again (WARNING: this will get
+# rid of any uncommitted source changes, too); use this as a last resort to
+# get the sources into a compilable state again after things have gone awry
+
+# dist: create a self-contained distribution tarball of the source
+
+# NOTES:
+
+# The realclean and dist targets use git commands and thus only work in a
+# working copy of the git repo, not in the static tarball snapshots produced
+# by the dist target.
+
+# On Linux systems running `make` will try to produce a Debian package. On
+# Linux distributions like Arch which are no Debian derivatives, the Debian
+# packaging tools are not available. In this case, `make` will stop right
+# before creating the actual package and leave the ready-made staged
+# installation tree under `packages/linux_make/build` from where it can be
+# copied or packaged up in any desired way.
+
+# The incremental and light builds assume an existing staging area
+# (packages/*/build directory) which is *not* cleaned before installing. This
+# makes it possible to update the existing staging area after recompiling just
+# a part of the system (all but Gem in the case of "incremental", only the
+# Pd core and a few essential externals in the case of "light"). Use `make
+# clean` beforehand if you want to install into a clean staging area.
+
+# When doing a `light` build, which only includes the most essential
+# externals, it may be desirable to manually include additional abstractions
+# and externals in the build. To these ends, after running `make light` you
+# can run `make` with the `foo_abs` or `foo_ext` target, where `foo` is the
+# name of the desired abstraction or external, respectively. E.g., you can run
+# `make light memento_abs pdlua_ext` to get a light build with the `memento`
+# abstraction and the `pdlua` external included. (This will not rebuild the
+# Debian package, though, so you'll have to install manually with `make
+# install` instead.) The names of the desired addons must be specified as
+# given in abstractions/Makefile and externals/Makefile, respectively (look
+# for targets looking like `foo_install`). Also note that even though a
+# subsequent `make install` will then include your addons, they won't be
+# enabled by default, so you'll have to do that manually in Purr Data's
+# `Startup` dialog. Simply adding the name of the addon in the `Libraries`
+# list should normally do the trick. Or you can add an option like `-lib foo`
+# when running Purr Data from the command line.
