# Dungeon Crawl Stone Soup
# GNU Makefile
#
# largely written by Steven Noonan <steven@uplinklabs.net>
#    (if something breaks, blame him.)
#

# Typical targets:
#    make
#    make debug
#    make debug-lite    # Like "make debug", but without all the spew.
#    make install
#    make debug install
#    -- note, unlike most programs, you need to specify build type when
#       installing even if you just built it.
# Typical parameters:
#    TILES         -- set to anything to enable tiles build
#
#    CROSSHOST     -- target system, eg, i386-pc-msdosdjgpp or i586-mingw32msvc
#
#    prefix        -- installation base.  Specify eg. /usr/local on Unix systems.
#    DESTDIR       -- installation staging area (the dir you intend to pack)
#    DATADIR       -- place to hold immutable files.  Can be either relative to
#                     "prefix" or absolute.
#    SAVEDIR       -- place to hold writeable data (saves, database, morgue
#                     dumps).  Can be relative to "prefix", absolute or placed
#                     in the user's home dir (~).  Remember to protect the ~
#                     from your shell!
#                     Warning, as of 0.8, directories shared between
#                     multiple system users are no longer supported.
#    SHAREDDIR     -- place to hold writeable data common to multiple
#                     versions of Crawl (scores, the logfile, ghosts).  Will
#                     be placed inside the SAVEDIR if not specified.
#       Layout examples:
#         prefix=~/crawl DATADIR=data/ SAVEDIR=saves/
#                  -- everything under ~/crawl
#         prefix=/usr/local
#                  -- system-wide installation
#
#    V             -- set to anything to enable verbose build
#
#    USE_ICC       -- set to use Intel's compiler
#    LTO           -- set for better optimization but slower compilation,
#                     requires gcc4.6+
#    NOASSERTS     -- set to disable assertion checks (ignored in debug mode)
#    NOWIZARD      -- set to disable wizard mode.  Use if you have untrusted
#                     remote players without DGL.
#
#    PROPORTIONAL_FONT -- set to a .ttf file you want to use for a proportional
#                         font; if not set, a copy of Bitstream Vera Sans
#                         shipped with Crawl will be used
#    MONOSPACED_FONT   -- monospaced font; Bitstream Vera Mono Sans
#    COPY_FONTS    -- force installing fonts
#
#    WEBTILES      -- set to anything to compile for Webtiles
#    WEBDIR        -- place to hold the Webtiles client data. Can be either
#                     relative to prefix or absolute.
#
#    ANDROID       -- perform an Android build (see docs/develop/android.txt)
#    TOUCH_UI      -- enable UI behaviour more compatible with touch-screens
#
#
# Requirements:
#    For tile builds, you need pkg-config.
#    You also need libpng, sdl, sdl-image and libfreetype -- if you got your
#    source from git, you can 'git submodule update' to fetch them; you can also
#    ask for a package with convenience libraries instead -- we'll try to provide
#    them somewhere in the near future.

# Compiler Flags
#
# The compiler flag variables are separated into their individual
# purposes, making it easier to deal with the various tools involved
# in a compile.
#
# These are also divided into global vs. local flags. So for instance,
# CFOPTIMIZE affects Crawl, Lua, and SQLite, while CFOPTIMIZE_L only
# affects Crawl.
#
# The variables are as follows:
# CFOPTIMIZE(_L) - Optimization flags
# CFWARN(_L) - Warning flags
# CFOTHERS(_L) - Anything else
