+# Makefile.pdlibbuilder dated 2016-11-02
+version = 0.4.3
+
+# Helper makefile for Pure Data external libraries.
+# Written by Katja Vetter March-June 2015 for the public domain. No warranties.
+# Inspired by Hans Christoph Steiner's Makefile Template and Stephan Beal's
+# ShakeNMake.
+#
+# Grab the newest version of Makefile.pdlibbuilder from
+# https://github.com/pure-data/pd-lib-builder/
+#
+# GNU make version >= 3.81 required.
+#
+#
+#=== characteristics ===========================================================
+#
+#
+# - defines build settings based on autodetected OS and architecture
+# - defines rules to build Pd class- or lib executables from C or C++ sources
+# - defines rules for libdir installation
+# - defines convenience targets for developer and user
+# - evaluates implicit dependencies for non-clean builds
+#
+#
+#=== basic usage ===============================================================
+#
+#
+# In your Makefile, define your Pd lib name and class files, and include
+# Makefile.pdlibbuilder at the end of the Makefile. Like so:
+#
+# ________________________________________________________________________
+#
+# # Makefile for mylib
+#
+# lib.name = mylib
+#
+# class.sources = myclass1.c myclass2.c
+#
+# datafiles = myclass1-help.pd myclass2-help.pd README.txt LICENSE.txt
+#
+# include Makefile.pdlibbuilder
+# ________________________________________________________________________
+#
+#
+# For files in class.sources it is assumed that class basename == source file
+# basename. The default target builds all classes as individual executables
+# with Pd's default extension for the platform. For anything more than the
+# most basic usage, continue reading.
+#
+#
+#=== list of Makefile.pdlibbuilder API variables ===============================
+#
+#
+# Variables available for definition in your library Makefile:
+#
+# - lib.name
+# - lib.setup.sources
+# - class.sources
+# - common.sources
+# - shared.sources
+# - <classname>.class.sources
+# - <classname>.class.ldflags
+# - <classname>.class.ldlibs
+# - cflags
+# - ldflags
+# - ldlibs
+# - datafiles
+# - datadirs
+# - makefiles
+# - makefiledirs
+# - externalsdir
+#
+# Optional multiline defines evaluated per operating system:
+#
+# - forLinux
+# - forDarwin
+# - forWindows
+#
+# Variables available for your makefile or make command line:
+#
+# - make-lib-executable
+# - suppress-wunused
+#
+# Path variables for make command line or environment:
+#
+# - PDDIR
+# - PDINCLUDEDIR
+# - PDBINDIR
+# - PDLIBDIR
+#
+# Standard make variables for make command line or environment:
+#
+# - CPPFLAGS
+# - CFLAGS
+# - LDFLAGS
+# - CC
+# - CXX
+# - INSTALL
+# - DESTDIR
+#
+# Deprecated path variables:
+#
+# - PD_PATH
+# - pdincludepath
+# - pdbinpath
+# - objectsdir
+#
+#
+#=== descriptions of Makefile.pdlibbuilder API variables =======================
+#
+#
+# lib.name:
+# Name of the library directory as it will be installed / distributed. Also the
+# name of the lib executable in the case where all classes are linked into
+# a single binary.
+#
+# lib.setup.sources:
+# Source file(s) (C or C++) which must be compiled only when linking all classes
+# into a single lib binary.
+#
+# class.sources:
+# All sources files (C or C++) for which the condition holds that
+# class name == source file basename.
+#
+# <classname>.class.sources:
+# Source file(s) (C or C++) specific to class <classname>. Use this for
+# multiple-source classes or when class name != source file basename.
+#
+# common.sources:
+# Source file(s) which must be statically linked to each class in the library.
+#
+# shared.sources:
+# Source file(s) (C or C++) to build a shared dynamic link lib, to be linked
+# with all class executables.
+#
+# cflags, ldflags, ldlibs:
+# Define cflags (preprocessor&compiler), ldflags (linker) and ldlibs (dynamic
+# link libs) for the whole library. These flags are added to platform-specific
+# flags defined by Makefile.pdlibbuilder.
+#
+# <classname>.class.ldflags and <classname>.class.ldlibs:
+# Define ldflags resp. ldlibs specific to class <classname>. These flags are
+# added to platform-specific flags defined by Makefile.pdlibbuilder, and flags
+# defined in your Makefile for the whole library. Note: cflags can not be
+# defined per class in the current implementation.
+#
+# datafiles and datadirs:
+# All extra files you want to include in binary distributions of the
+# library: abstractions and help patches, example patches, meta patch, readme
+# and license texts, manuals, sound files, etcetera. Use 'datafiles' for all
+# files that should go into your lib rootdir and 'datadirs' for complete
+# directories you want to copy from source to distribution.
+#
+# forLinux, forDarwin, forWindows:
+# Shorthand for 'variable definitions for Linux only' etc. Use like:
+# define forLinux
+# cflags += -DLINUX
+# class.sources += linuxthing.c
+# endef
+#
+# makefiles and makefiledirs:
+# Extra makefiles or directories with makefiles that should be made in sub-make
+# processes.
+#
+# make-lib-executable:
+# When this variable is defined 'yes' in your makefile or as command argument,
+# Makefile.pdlibbuilder will try to build all classes into a single library
+# executable (but it will force exit if lib.setup.sources is undefined).
+# If your makefile defines 'make-lib-executable=yes' as the library default,
+# this can still be overriden with 'make-lib-executable=no' as command argument
+# to build individual class executables (the Makefile.pdlibbuilder default.)
+#
+# suppress-wunused:
+# When this variable is defined ('yes' or any other value), -Wunused-variable,
+# -Wunused-parameter, -Wunused-value and -Wunused-function are suppressed,
+# but the other warnings from -Wall are retained.
+#
+# PDDIR:
+# Root directory of 'portable' pd package. When defined, PDINCLUDEDIR and
+# PDBINDIR will be evaluated as $(PDDIR)/src and $(PDDIR)/bin.
+#
+# PDINCLUDEDIR:
+# Directory where Pd API m_pd.h should be found, and other Pd header files.
+# Overrides the default search path.
+#
+# PDBINDIR:
+# Directory where pd.dll should be found for linking (Windows only). Overrides
+# the default search path.
+#
+# PDLIBDIR:
+# Root directory for installation of Pd library directories. Overrides the
+# default install location.
+#
+# DESTDIR:
+# Prepended path component for staged install.
+#
+# CPPFLAGS:
+# Preprocessor flags which are not strictly required for building.
+#
+# CFLAGS:
+# Compiler flags which are not strictly required for building. Compiler flags
+# defined by Makefile.pdlibbuilder for warning, optimization and architecture
+# specification are overriden by CFLAGS.
+#
+# LDFLAGS:
+# Linker flags which are not strictly required for building. Linker flags
+# defined by Makefile.pdlibbuilder for architecture specification are overriden
+# by LDFLAGS.
+#
+# CC and CXX:
+# C and C++ compiler programs as defined in your build environment.
+#
+# INSTALL
+# Definition of install program.
+#
+# PD_PATH:
+# Equivalent to PDDIR. Supported for compatibility with pd-extended central
+# makefile, but deprecated otherwise.
+#
+# objectsdir:
+# Root directory for installation of Pd library directories, like PDLIBDIR but
+# not overridable by environment. Supported for compatibility with pd-extended
+# central makefile, but deprecated otherwise.
+#
+# pdincludepath, pdbinpath:
+# As PDINCLUDEDIR and PDBINDIR but not overridable by environment. Deprecated
+# as user variables.
+#
+#
+#=== paths =====================================================================
+#
+#
+# Source files in directories other than current working directory must be
+# prefixed with their relative path. Do not rely on VPATH or vpath.
+# Object (.o) files are built in the directory of their source files.
+# Executables are built in current working directory.
+#
+# Default search path for m_pd.h and other API header files is platform
+# dependent, and overridable by PDINCLUDEDIR:
+#
+# Linux: /usr/include/pd
+#
+# OSX: /Applications/Pd*.app/Contents/Resources/src
+#
+# Windows: %PROGRAMFILES%/pd/src
+#
+# Default location to install pd libraries is platform dependent, and
+# overridable by PDLIBDIR:
+#
+# Linux: /usr/local/lib/pd-externals
+# OSX: ~/Library/Pd
+# Windows: %APPDATA%/Pd
+#
+# https://puredata.info/docs/faq/how-do-i-install-externals-and-help-files
+# The rationale for not installing to ~/pd-externals by default on Linux
+# is that some people share the home dir between 32 and 64 bit installations.
+#
+#
+#=== targets ===================================================================
+#
+#
+# all: build $(executables) plus optional post target
+# post: target to build after $(executables)
+# alldebug: build all with -g option turned on for debug symbols
+# <classname>: force clean build of an individual class
+# <sourcefile>.pre: make preprocessor output file in current working directory
+# <sourcefile>.lst: make asm/source output file in current working directory
+#
+# install: install executables and data files
+# clean: remove build products from source tree
+#
+# help: print help text
+# vars: print makefile variables
+# allvars: print all variables
+# depend: print generated prerequisites
+# coffee: dummy target
+#
+# Variable $(executables) expands to class executables plus optional shared lib,
+# or alternatively to single lib executable when make-lib-executable=true.
+# Targets pre and post can be defined by library makefile. Make sure to include
+# Makefile.pdlibbuilder first so default target all will not be redefined.
+#
+#
+#=== Pd-extended libdir concept ================================================
+#
+#
+# For libdir layout as conceived by Hans-Christoph Steiner, see:
+#
+# https://puredata.info/docs/developer/Libdir
+#
+# Files README.txt, LICENSE.txt and <lib.name>-meta.pd are part of the libdir
+# convention. Help patches for each class and abstraction are supposed to be
+# available. Makefile.pdlibbuilder does not force the presence of these files
+# however. It does not automatically include such files in libdir installations.
+# Data files you want to include in distributions must be defined explicitly in
+# your Makefile.
+#
+#
+#=== Makefile.pdlibbuilder syntax conventions ==================================
+#
+#
+# Makefile.pdlibbuilder variable names are lower case. Default make variables,
+# environment variables, and standard user variables (CC, CXX, CFLAGS, DESTDIR)
+# are upper case. Use target 'allvars' to print all variables and their values.
+#
+# 'Fields' in data variables are separated by dots, like in 'foo.class.sources'.
+# Words in variables expressing a function or command are separated by dashes,
+# like in 'make-lib-executable'.
+#
+#
+#=== useful make options =======================================================
+#
+#
+# Use 'make -d <target>' to print debug details of the make process.
+# Use 'make -p <target>' to print make's database.
+#
+#
+#=== TODO ======================================================================
+#
