# 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

# release: used by OSX to make a dmg file ready to release

    40

    41

# Options:

    42

#

    43

# Summary of OS choice defines

    44

# WIN32: building on Windows

    45

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

    46

# OSX: building on Mac OS X

    47

# MORPHOS: building on MorphOS

    48

# BEOS: building on BeOS

    49

# SUNOS: building on SunOS (Solaris)

    50

#

    51

# Summary of library choice defines

    52

# WITH_ZLIB: savegames using zlib

    53

# WITH_PNG: screenshots using PNG

    54

# WITH_SDL: SDL video driver support

    55

#

    56

# Summary of other defines:

    57

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

    58

# DEBUG: build in debug mode

    59

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

    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

#       This can still be overriden by the music.extmidi openttd.cfg option.

    67

# WITH_NETWORK: enable networking

    68

# DEDICATED: allows compilation on UNIX without SDL. Useful for dedicated servers

    69

#

    70

# Paths:

    71

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

    72

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

    73

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

    74

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

    75

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

    76

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

    77

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

    78

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

    79

# also define all the following paths before building).

    80

#

    81

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

    82

# None of these paths have to end with /

    83

# PREFIX:	Normally /usr/local

    84

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

    85

#		with $PREFIX)

    86

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

    87

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

    88

#		are only put here if USE_HOMEDIR is true, otherwise they are placed in

    89

#		PERSONAL_DIR/scenario

    90

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

    91

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

    92

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

    93

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

    94

# SECOND_DATA_PATH  Use this data dir if a file is not found in the data dir in the data path

    95

# CUSTOM_LANG_PATH  If this is set, it will use the path given to search for lng files

    96

#		instead of the lang dir in the data path

    97

#   NOTE: both SECOND_DATA_PATH and CUSTOM_LANG_PATH uses paths relative to where OTTD is opened

    98

#

    99

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

   100

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

   101

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

   102

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

   103

# 		install' and is not saved in Makefile.config

   104

#               (Note that DESTDIR is checked if DEST_DIR is not set.)

   105

#

   106

# STATIC: link statically

   107

# CYGWIN: build in Cygwin environment

   108

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

   109

#

   110

# VERBOSE: show full compiler invocations instead of brief progress messages

   111

#

   112

# Special for crosscompiling there are some commands available:

   113

#

   114

# ENDIAN_FORCE: forces the endian-check to give a certain result. Can be either BE or LE.

   115

# WINDRES: the location of your windres

   116

# CC_HOST: the gcc of your localhost if you are making a target that produces incompatible executables

   117

# CFLAGS_HOST: cflags used for CC_HOST. Make it something if you are getting errors when you try to compi

   118

#		windows executables on linux. (just: CFLAGS_HOST:='-I' or something)

   119

#

   120

# Experimental (does not work properly):

   121

# WITH_DIRECTMUSIC: enable DirectMusic MIDI support
