54 PLATFORM SPECIFIC NOTES
55 =======================
60 Recent development is with GNU/Linux. I have tested compilation on
61 FreeBSD v4.0, BSD/OS v3.0, and Solaris v8 (gcc 32-bit), and IA64 (gcc)
62 , and Microsoft Windows 2000 (Visual C++ 6.0, cygwin, and mingw32).
64 Visual C++ Installation
65 -----------------------
66 Run make.bat from the root directory (Note, make.bat is out of date
67 and is currently broken)
71 The file /usr/i686-pc-wygwin/include/cygwin/in.h has a bug. The line
72 struct in_addr6 sin6_addr;
75 getopt_long appears broken, configure.in checks for cygwin to use
76 bundled version of getopt_long.
82 These are generic installation instructions.
84 The `configure' shell script attempts to guess correct values for
85 various system-dependent variables used during compilation. It uses
86 those values to create a `Makefile' in each directory of the package.
87 It may also create one or more `.h' files containing system-dependent
88 definitions. Finally, it creates a shell script `config.status' that
89 you can run in the future to recreate the current configuration, a file
90 `config.cache' that saves the results of its tests to speed up
91 reconfiguring, and a file `config.log' containing compiler output
92 (useful mainly for debugging `configure').
94 If you need to do unusual things to compile the package, please try
95 to figure out how `configure' could check whether to do them, and mail
96 diffs or instructions to the address given in the `README' so they can
97 be considered for the next release. If at some point `config.cache'
98 contains results you don't want to keep, you may remove or edit it.
100 The file `configure.in' is used to create `configure' by a program
101 called `autoconf'. You only need `configure.in' if you want to change
102 it or regenerate `configure' using a newer version of `autoconf'.
104 The simplest way to compile this package is:
106 1. `cd' to the directory containing the package's source code and type
107 `./configure' to configure the package for your system. If you're
108 using `csh' on an old version of System V, you might need to type
109 `sh ./configure' instead to prevent `csh' from trying to execute
112 Running `configure' takes awhile. While running, it prints some
113 messages telling which features it is checking for.
115 2. Type `make' to compile the package.
117 3. Optionally, type `make check' to run any self-tests that come with
120 4. Type `make install' to install the programs and any data files and
123 5. You can remove the program binaries and object files from the
124 source code directory by typing `make clean'. To also remove the
125 files that `configure' created (so you can compile the package for
126 a different kind of computer), type `make distclean'. There is
127 also a `make maintainer-clean' target, but that is intended mainly
128 for the package's developers. If you use it, you may have to get
129 all sorts of other programs in order to regenerate files that came
130 with the distribution.
132 Compilers and Options
133 =====================
135 Some systems require unusual options for compilation or linking that
136 the `configure' script does not know about. You can give `configure'
137 initial values for variables by setting them in the environment. Using
138 a Bourne-compatible shell, you can do that on the command line like
140 CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
142 Or on systems that have the `env' program, you can do it like this:
143 env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
145 Compiling For Multiple Architectures
146 ====================================
148 You can compile the package for more than one kind of computer at the
149 same time, by placing the object files for each architecture in their
150 own directory. To do this, you must use a version of `make' that
151 supports the `VPATH' variable, such as GNU `make'. `cd' to the
152 directory where you want the object files and executables to go and run
153 the `configure' script. `configure' automatically checks for the
154 source code in the directory that `configure' is in and in `..'.
156 If you have to use a `make' that does not supports the `VPATH'
157 variable, you have to compile the package for one architecture at a time
158 in the source code directory. After you have installed the package for
159 one architecture, use `make distclean' before reconfiguring for another
165 By default, `make install' will install the package's files in
166 `/usr/local/bin', `/usr/local/man', etc. You can specify an
167 installation prefix other than `/usr/local' by giving `configure' the
168 option `--prefix=PATH'.
170 You can specify separate installation prefixes for
171 architecture-specific files and architecture-independent files. If you
172 give `configure' the option `--exec-prefix=PATH', the package will use
173 PATH as the prefix for installing programs and libraries.
174 Documentation and other data files will still use the regular prefix.
176 In addition, if you use an unusual directory layout you can give
177 options like `--bindir=PATH' to specify different values for particular
178 kinds of files. Run `configure --help' for a list of the directories
179 you can set and what kinds of files go in them.
181 If the package supports it, you can cause programs to be installed
182 with an extra prefix or suffix on their names by giving `configure' the
183 option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
188 Some packages pay attention to `--enable-FEATURE' options to
189 `configure', where FEATURE indicates an optional part of the package.
190 They may also pay attention to `--with-PACKAGE' options, where PACKAGE
191 is something like `gnu-as' or `x' (for the X Window System). The
192 `README' should mention any `--enable-' and `--with-' options that the
195 For packages that use the X Window System, `configure' can usually
196 find the X include and library files automatically, but if it doesn't,
197 you can use the `configure' options `--x-includes=DIR' and
198 `--x-libraries=DIR' to specify their locations.
200 Specifying the System Type
201 ==========================
203 There may be some features `configure' can not figure out
204 automatically, but needs to determine by the type of host the package
205 will run on. Usually `configure' can figure that out, but if it prints
206 a message saying it can not guess the host type, give it the
207 `--host=TYPE' option. TYPE can either be a short name for the system
208 type, such as `sun4', or a canonical name with three fields:
211 See the file `config.sub' for the possible values of each field. If
212 `config.sub' isn't included in this package, then this package doesn't
213 need to know the host type.
215 If you are building compiler tools for cross-compiling, you can also
216 use the `--target=TYPE' option to select the type of system they will
217 produce code for and the `--build=TYPE' option to select the type of
218 system on which you are compiling the package.
223 If you want to set default values for `configure' scripts to share,
224 you can create a site shell script called `config.site' that gives
225 default values for variables like `CC', `cache_file', and `prefix'.
226 `configure' looks for `PREFIX/share/config.site' if it exists, then
227 `PREFIX/etc/config.site' if it exists. Or, you can set the
228 `CONFIG_SITE' environment variable to the location of the site script.
229 A warning: not all `configure' scripts look for a site script.
234 `configure' recognizes the following options to control how it
238 Use and save the results of the tests in FILE instead of
239 `./config.cache'. Set FILE to `/dev/null' to disable caching, for
240 debugging `configure'.
243 Print a summary of the options to `configure', and exit.
248 Do not print messages saying which checks are being made. To
249 suppress all normal output, redirect it to `/dev/null' (any error
250 messages will still be shown).
253 Look for the package's source code in directory DIR. Usually
254 `configure' can determine that directory automatically.
257 Print the version of Autoconf used to generate the `configure'
260 `configure' also accepts some other, not widely useful, options.
