# Usage

#

     7

     8

# Synopsis:

     9

#

    10

# make WITH_ZLIB=1 UNIX=1 MANUAL_CONFIG=1

    11

#

    12

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

    13

#

    14

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

    15

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

    16

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

    17

# Makefile.config take precedence to the commandline options.

    18

#

    19

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

    20

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

    21

# options at all.)

    22

    23

# Targets:

    24

#

    25

# Defaults to building binary

    26

# clean: remove intermediate build files

    27

# mrproper: remove intermediate files and makefile configuration

    28

# upgradeconf: add new options to old Makefile.config

    29

# osx: OS X application

    30

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

    31

    32

# Options:

    33

#

    34

# Summary of OS choice defines

    35

# WIN32: building on Windows

    36

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

    37

# OSX: building on Mac OS X

    38

# MORPHOS: building on MorphOS

    39

# BEOS: building on BeOS

    40

# SUNOS: building on SunOS (Solaris)

    41

#

    42

# Summary of library choice defines

    43

# WITH_ZLIB: savegames using zlib

    44

# WITH_PNG: screenshots using PNG

    45

# WITH_SDL: SDL video driver support

    46

#

    47

# Summary of other defines:

    48

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

    49

# DEBUG: build in debug mode

    50

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

    51

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

    52

#             a <TODO> mark)

    53

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

    54

#          where it normally would print the revision number

    55

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

    56

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

    57

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

    58

# WITH_DIRECTMUSIC: enable DirectMusic MIDI support

    59

# WITH_NETWORK: enable networking

    60

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

    61

# MAX_NUM_AUTOSAVES: sets the number of autosaves the games will make before starting

    62

#		to overwrite the old ones. If not set, the game will use 16.

    63

#		NOTE: assign a number, not a string of a number

    64

#

    65

# Paths:

    66

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

    67

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

    68

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

    69

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

    70

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

    71

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

    72

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

    73

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

    74

# also define all the following paths before building).

    75

#

    76

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

    77

# None of these paths have to end with /

    78

# PREFIX:	Normally /usr/local

    79

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

    80

#		with $PREFIX)

    81

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

    82

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

    83

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

    84

#		PERSONAL_DIR/scenario

    85

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

    86

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

    87

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

    88

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

    89

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

    90

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

    91

#		instead of the lang dir in the data path

    92

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

    93

#

    94

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

    95

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

    96

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

    97

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

    98

# 		install' and is not saved in Makefile.config

    99

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

   100

#

   101

# STATIC: link statically

   102

# CYGWIN: build in Cygwin environment

   103

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

   104

#

   105

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

   106

#

   107

# Special for crosscompiling there are some commands available:

   108

#

   109

# BUILD_UNIVERSAL_BINARY: builds a universal binary for OSX. Make sure you got both PPC and x86 libs

   110

#

   111

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

   112

#	PREPROCESSOR is always used on all OSX targets and will make the preprocessor pick the right endian.

   113

#	this means that you don't have to think about endianess when compiling for OSX.

   114

#	Very useful for universal binaries and crosscompilers. Not sure if it works on non OSX targets

   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)
