# Usage

    15

#

    16

    17

# Synopsis:

    18

#

    19

# make WITH_ZLIB=1 UNIX=1 MANUAL_CONFIG=1

    20

#

    21

# (See below for the list of possible options.)

    22

#

    23

# Alternately, you can run make without the MANUAL_CONFIG part. It then

    24

# generates Makefile.config, where you can customize all the options.

    25

# However beware that for all subsequent calls the option values from

    26

# Makefile.config take precedence to the commandline options.

    27

#

    28

# (That means that you probably want to either specify the options on command

    29

# line together with MANUAL_CONFIG=1 or you want to specify no commandline

    30

# options at all.)

    31

    32

# Targets:

    33

#

    34

# Defaults to building binary

    35

# clean: remove intermediate build files

    36

# mrproper: remove intermediate files and makefile configuration

    37

# upgradeconf: add new options to old Makefile.config

    38

# osx: OS X application

    39

    40

# Options:

    41

#

    42

# Summary of OS choice defines

    43

# WIN32: building on Windows

    44

# UNIX: building on *nix derivate (Linux, FreeBSD)

    45

# OSX: building on Mac OS X

    46

# MORPHOS: building on MorphOS

    47

# BEOS: building on BeOS

    48

# SUNOS: building on SunOS (Solaris)

    49

#

    50

# Summary of library choice defines

    51

# WITH_ZLIB: savegames using zlib

    52

# WITH_PNG: screenshots using PNG

    53

# WITH_SDL: SDL video driver support

    54

#

    55

# Summary of other defines:

    56

# MANUAL_CONFIG: do not use Makefile.config, config options set manually

    57

# DEBUG: build in debug mode

    58

# PROFILE: build in profile mode, disables -s and -fomit-frame-pointer

    59

# DISPLAY_WARNINGS: when off, some errors are not displayed while compiling

    60

# TRANSLATOR: build in translator mode (untranslated strings are prepended by

    61

#             a <TODO> mark)

    62

# RELEASE: this will be the released version number. It replaces all places

    63

#          where it normally would print the revision number

    64

# MIDI: if set, it will use it as custom path to midi player.

    65

#  If unset, it will use the hardcoded path in the c code

    66

# NOVERBOSE: supress all warnings and errors during compilation.

    67

#  It looks nicer, but you will not know what went wrong. Use it on released (stable) sources only

    68

#

    69

# Paths:

    70

# INSTALL: If not set, the game uses the directory of the binary to

    71

# store everything (lang, data, gm, save and openttd.cfg), this is the `old' behaviour. 

    72

# In this case, none of the following paths are used, you also should _not_

    73

# use `make install', but copy the required stuff yourself (or just play out

    74

# of you source directory, which should work fine).

    75

# If you want to use `make install' to install the game globally, you should

    76

# define it _before_ you build the game. If you only define INSTALL when you

    77

# do `make install', the game won't be able to find it's files (so you should

    78

# also define all the following paths before building).

    79

#

    80

# So, the following paths should be defined if INSTALL is defined.

    81

# None of these paths have to end with /

    82

# PREFIX:	Normally /usr/local

    83

# BINARY_DIR:	The location of the binary, normally games. (Will be prefixed

    84

#		with $PREFIX)

    85

# DATA_DIR: 	The location of the data (lang, data and gm), normally 

    86

#		share/games/openttd. (Will be prefixed with $PREFIX)

    87

# PERSONAL_DIR:	The directory where openttd.cfg and the save folder will be

    88

#		stored. You cannot use ~ here, define USE_HOMEDIR for that.

    89

# USE_HOMEDIR:	If this variable is set, PERSONAL_DIR will be prefixed with

    90

#		~/ at runtime (the user's homedir)

    91

#

    92

# DEST_DIR:	make install will use this directory instead of the filesystem

    93

# 		root to install its files. This should normally not be used by

    94

# 		ordinary users, currently it is only used for the debian

    95

# 		packaging. This value should only be set when calling `make

    96

# 		install' and is not saved in Makefile.config

    97

#

    98

# STATIC: link statically

    99

# CYGWIN: build in Cygwin environment

   100

# MINGW: build with MingW compiler, link with MingW libraries

   101

#

   102

# Experimental (does not work properly):

   103

# WITH_NETWORK: enable networking

   104

# WITH_DIRECTMUSIC: enable DirectMusic MIDI support
