# FreeType 2 host platform detection rules

# Copyright 1996-2000, 2001, 2002, 2003, 2006, 2008 by
# David Turner, Robert Wilhelm, and Werner Lemberg.

# This sub-Makefile is in charge of detecting the current platform.  It sets
# the following variables:
#   BUILD_DIR    The configuration and system-specific directory.  Usually
#                `freetype/builds/$(PLATFORM)' but can be different for
#                custom builds of the library.
# The following variables must be defined in system specific `'
# files:
#   PLATFORM     The detected platform.  This will default to `ansi' if
#                auto-detection fails.
#   CONFIG_FILE  The configuration sub-makefile to use.  This usually depends
#                on the compiler defined in the `CC' environment variable.
#   DELETE       The shell command used to remove a given file.
#   COPY         The shell command used to copy one file.
#   SEP          The platform-specific directory separator.
#   COMPILER_SEP The separator used in arguments of the compilation tools.
#   CC           The compiler to use.
# You need to set the following variable(s) before calling it:
#   TOP_DIR      The top-most directory in the FreeType library source
#                hierarchy.  If not defined, it will default to `.'.

# Set auto-detection default to `ansi' resp. UNIX-like operating systems.
PLATFORM     := ansi
DELETE       := $(RM)
COPY         := cp
CAT          := cat
SEP          := /


# These two assignments must be delayed.

# We define the BACKSLASH variable to hold a single back-slash character.
# This is needed because a line like
#   SEP := \
# does not work with GNU Make (the backslash is interpreted as a line
# continuation).  While a line like
#   SEP := \\
# really defines $(SEP) as `\' on Unix, and `\\' on Dos and Windows!
BACKSLASH := $(strip \ )

# Find all auto-detectable platforms.
PLATFORMS := $(notdir $(subst /,,$(wildcard $(BUILD_CONFIG)/*/

# Filter out platform specified as setup target.
PLATFORM := $(firstword $(filter $(MAKECMDGOALS),$(PLATFORMS)))

# If no setup target platform was specified, enable auto-detection/
# default platform.
ifeq ($(PLATFORM),)
  PLATFORM := ansi

# If the user has explicitly asked for `ansi' on the command line,
# disable auto-detection.
ifeq ($(findstring ansi,$(MAKECMDGOALS)),)
  # Now, include all detection rule files found in the `builds/<system>'
  # directories.  Note that the calling order of the various `'
  # files isn't predictable.
  include $(wildcard $(BUILD_CONFIG)/*/

# In case no detection rule file was successful, use the default.
  setup: std_setup
  .PHONY: setup

# The following targets are equivalent, with the exception that they use
# a slightly different syntax for the `echo' command.
# std_setup: defined for most (i.e. Unix-like) platforms
# dos_setup: defined for Dos-ish platforms like Dos, Windows & OS/2
.PHONY: std_setup dos_setup
