3Build Remarks
4=============
5
6(These are remarks for building on UNIX-like systems, instructions for Windows
7systems are provided in the file INSTALL.Windows.txt)
8
9* Standard build:
10
11  $ ./configure && make
12
13* Debug build:
14
15  $ ./configure --enable-debug && make
16
17* Graphics:
18    * Graphics output support can be disabled by passing certain arguments to
19      configure or the C preprocessor:
20
21    * Disable Magick++:
22
23      $ ./configure --disable-magick
24      OR
25      $ make CPPFLAGS="-DDISABLE_MAGICK"
26
27    * Disable GD library:
28
29      $ ./configure --disable-gd
30      OR
31      $ make CPPFLAGS="-DDISABLE_GD"
32
33    * Disable graphics support:
34
35      $ ./configure --disable-magick --disable-gd
36      OR
37      $ make CPPFLAGS="-DDISABLE_GRAPHICS"
38
39  None of these DISABLE_* macros can be set from the configure script.
40
41* Nonstandard locations of libraries:
42
43  configure can be pointed to the correct locations of the boost libraries, gd
44  and Magick++ by using the "--with-*" options (they should point to the
45  *prefix* not the headers -e.g. /usr instead of /usr/include-). They are:
46    --with-gd
47    --with-magick
48    --with-boost
49    --with-boost-program_options
50    --with-boost-thread
51
52* Magick++ support can be provided by either ImageMagick++  or
53  GraphicsMagick++, there's currently no way to choose one over the other.
54
55* If the configure script fails to locate your boost-program-options
56  and/or boosy-thread installation, first locate it (e.g.
57  /usr/lib/libboost_program_options-gcc41-mt-1_34.*) and then pass the suffix
58  as an argument to configure as follows: (for the above example):
59
60  $ ./configure --with-boost-program-options=gcc41-mt-1_34

74
75Basic Installation
76==================
77
78These are generic installation instructions.
79
80   The `configure' shell script attempts to guess correct values for
81various system-dependent variables used during compilation.  It uses
82those values to create a `Makefile' in each directory of the package.
83It may also create one or more `.h' files containing system-dependent
84definitions.  Finally, it creates a shell script `config.status' that
85you can run in the future to recreate the current configuration, and a
86file `config.log' containing compiler output (useful mainly for
87debugging `configure').
88
89   It can also use an optional file (typically called `config.cache'
90and enabled with `--cache-file=config.cache' or simply `-C') that saves
91the results of its tests to speed up reconfiguring.  (Caching is
92disabled by default to prevent problems with accidental use of stale
93cache files.)
94
95   If you need to do unusual things to compile the package, please try
96to figure out how `configure' could check whether to do them, and mail
97diffs or instructions to the address given in the `README' so they can
98be considered for the next release.  If you are using the cache, and at
99some point `config.cache' contains results you don't want to keep, you
100may remove or edit it.
101
102   The file `configure.ac' (or `configure.in') is used to create
103`configure' by a program called `autoconf'.  You only need
104`configure.ac' if you want to change it or regenerate `configure' using
105a newer version of `autoconf'.
106
107The simplest way to compile this package is:
108
109  1. `cd' to the directory containing the package's source code and type
110     `./configure' to configure the package for your system.  If you're
111     using `csh' on an old version of System V, you might need to type
112     `sh ./configure' instead to prevent `csh' from trying to execute
113     `configure' itself.
114
115     Running `configure' takes awhile.  While running, it prints some
116     messages telling which features it is checking for.
117
118  2. Type `make' to compile the package.
119
120  3. Optionally, type `make check' to run any self-tests that come with
121     the package.
122
123  4. Type `make install' to install the programs and any data files and
124     documentation.
125
126  5. You can remove the program binaries and object files from the
127     source code directory by typing `make clean'.  To also remove the
128     files that `configure' created (so you can compile the package for
129     a different kind of computer), type `make distclean'.  There is
130     also a `make maintainer-clean' target, but that is intended mainly
131     for the package's developers.  If you use it, you may have to get
132     all sorts of other programs in order to regenerate files that came
133     with the distribution.
134
135Compilers and Options
136=====================
137
138Some systems require unusual options for compilation or linking that the
139`configure' script does not know about.  Run `./configure --help' for
140details on some of the pertinent environment variables.
141
142   You can give `configure' initial values for configuration parameters
143by setting variables in the command line or in the environment.  Here
144is an example:
145
146     ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix
147
148   *Note Defining Variables::, for more details.
149
150Compiling For Multiple Architectures
151====================================
152
153You can compile the package for more than one kind of computer at the
154same time, by placing the object files for each architecture in their
155own directory.  To do this, you must use a version of `make' that
156supports the `VPATH' variable, such as GNU `make'.  `cd' to the
157directory where you want the object files and executables to go and run
158the `configure' script.  `configure' automatically checks for the
159source code in the directory that `configure' is in and in `..'.
160
161   If you have to use a `make' that does not support the `VPATH'
162variable, you have to compile the package for one architecture at a
163time in the source code directory.  After you have installed the
164package for one architecture, use `make distclean' before reconfiguring
165for another architecture.
166
167Installation Names
168==================
169
170By default, `make install' installs the package's commands under
171`/usr/local/bin', include files under `/usr/local/include', etc.  You
172can specify an installation prefix other than `/usr/local' by giving
173`configure' the option `--prefix=PREFIX'.
174
175   You can specify separate installation prefixes for
176architecture-specific files and architecture-independent files.  If you
177pass the option `--exec-prefix=PREFIX' to `configure', the package uses
178PREFIX as the prefix for installing programs and libraries.
179Documentation and other data files still use the regular prefix.
180
181   In addition, if you use an unusual directory layout you can give
182options like `--bindir=DIR' to specify different values for particular
183kinds of files.  Run `configure --help' for a list of the directories
184you can set and what kinds of files go in them.
185
186   If the package supports it, you can cause programs to be installed
187with an extra prefix or suffix on their names by giving `configure' the
188option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
189
190Optional Features
191=================
192
193Some packages pay attention to `--enable-FEATURE' options to
194`configure', where FEATURE indicates an optional part of the package.
195They may also pay attention to `--with-PACKAGE' options, where PACKAGE
196is something like `gnu-as' or `x' (for the X Window System).  The
197`README' should mention any `--enable-' and `--with-' options that the
198package recognizes.
199
200   For packages that use the X Window System, `configure' can usually
201find the X include and library files automatically, but if it doesn't,
202you can use the `configure' options `--x-includes=DIR' and
203`--x-libraries=DIR' to specify their locations.
204
205Specifying the System Type
206==========================
207
208There may be some features `configure' cannot figure out automatically,
209but needs to determine by the type of machine the package will run on.
210Usually, assuming the package is built to be run on the _same_
211architectures, `configure' can figure that out, but if it prints a
212message saying it cannot guess the machine type, give it the
213`--build=TYPE' option.  TYPE can either be a short name for the system
214type, such as `sun4', or a canonical name which has the form:
215
216     CPU-COMPANY-SYSTEM
217
218where SYSTEM can have one of these forms:
219
220     OS KERNEL-OS
221
222   See the file `config.sub' for the possible values of each field.  If
223`config.sub' isn't included in this package, then this package doesn't
224need to know the machine type.
225
226   If you are _building_ compiler tools for cross-compiling, you should
227use the option `--target=TYPE' to select the type of system they will
228produce code for.
229
230   If you want to _use_ a cross compiler, that generates code for a
231platform different from the build platform, you should specify the
232"host" platform (i.e., that on which the generated programs will
233eventually be run) with `--host=TYPE'.
234
235Sharing Defaults
236================
237
238If you want to set default values for `configure' scripts to share, you
239can create a site shell script called `config.site' that gives default
240values for variables like `CC', `cache_file', and `prefix'.
241`configure' looks for `PREFIX/share/config.site' if it exists, then
242`PREFIX/etc/config.site' if it exists.  Or, you can set the
243`CONFIG_SITE' environment variable to the location of the site script.
244A warning: not all `configure' scripts look for a site script.
245
246Defining Variables
247==================
248
249Variables not defined in a site shell script can be set in the
250environment passed to `configure'.  However, some packages may run
251configure again during the build, and the customized values of these
252variables may be lost.  In order to avoid this problem, you should set
253them in the `configure' command line, using `VAR=value'.  For example:
254
255     ./configure CC=/usr/local2/bin/gcc
256
257causes the specified `gcc' to be used as the C compiler (unless it is
258overridden in the site shell script).  Here is a another example:
259
260     /bin/bash ./configure CONFIG_SHELL=/bin/bash
261
262Here the `CONFIG_SHELL=/bin/bash' operand causes subsequent
263configuration-related scripts to be executed by `/bin/bash'.
264
265`configure' Invocation
266======================
267
268`configure' recognizes the following options to control how it operates.
269
270`--help'
271`-h'
272     Print a summary of the options to `configure', and exit.
273
274`--version'
275`-V'
276     Print the version of Autoconf used to generate the `configure'
277     script, and exit.
278
279`--cache-file=FILE'
280     Enable the cache: use and save the results of the tests in FILE,
281     traditionally `config.cache'.  FILE defaults to `/dev/null' to
282     disable caching.
283
284`--config-cache'
285`-C'
286     Alias for `--cache-file=config.cache'.
287
288`--quiet'
289`--silent'
290`-q'
291     Do not print messages saying which checks are being made.  To
292     suppress all normal output, redirect it to `/dev/null' (any error
293     messages will still be shown).
294
295`--srcdir=DIR'
296     Look for the package's source code in directory DIR.  Usually
297     `configure' can determine that directory automatically.
298
299`configure' also accepts some other, not widely useful, options.  Run
300`configure --help' for more details.
