14 To compile and install Calf, you need:
16 - POSIX-compliant operating system
17 - G++ version 4.0 or higher (tested with 4.1.3)
18 - GTK+2 headers and libraries (glib 2.10, gtk+ 2.12)
20 Optional but recommended:
21 - JACK header and libraries (tested with 0.109.0)
29 These are generic installation instructions.
31 The `configure' shell script attempts to guess correct values for
32 various system-dependent variables used during compilation. It uses
33 those values to create a `Makefile' in each directory of the package.
34 It may also create one or more `.h' files containing system-dependent
35 definitions. Finally, it creates a shell script `config.status' that
36 you can run in the future to recreate the current configuration, and a
37 file `config.log' containing compiler output (useful mainly for
38 debugging `configure').
40 It can also use an optional file (typically called `config.cache'
41 and enabled with `--cache-file=config.cache' or simply `-C') that saves
42 the results of its tests to speed up reconfiguring. (Caching is
43 disabled by default to prevent problems with accidental use of stale
46 If you need to do unusual things to compile the package, please try
47 to figure out how `configure' could check whether to do them, and mail
48 diffs or instructions to the address given in the `README' so they can
49 be considered for the next release. If you are using the cache, and at
50 some point `config.cache' contains results you don't want to keep, you
51 may remove or edit it.
53 The file `configure.ac' (or `configure.in') is used to create
54 `configure' by a program called `autoconf'. You only need
55 `configure.ac' if you want to change it or regenerate `configure' using
56 a newer version of `autoconf'.
58 The simplest way to compile this package is:
60 1. `cd' to the directory containing the package's source code and type
61 `./configure' to configure the package for your system. If you're
62 using `csh' on an old version of System V, you might need to type
63 `sh ./configure' instead to prevent `csh' from trying to execute
66 Running `configure' takes awhile. While running, it prints some
67 messages telling which features it is checking for.
69 2. Type `make' to compile the package.
71 3. Optionally, type `make check' to run any self-tests that come with
74 4. Type `make install' to install the programs and any data files and
77 5. You can remove the program binaries and object files from the
78 source code directory by typing `make clean'. To also remove the
79 files that `configure' created (so you can compile the package for
80 a different kind of computer), type `make distclean'. There is
81 also a `make maintainer-clean' target, but that is intended mainly
82 for the package's developers. If you use it, you may have to get
83 all sorts of other programs in order to regenerate files that came
84 with the distribution.
89 Some systems require unusual options for compilation or linking that the
90 `configure' script does not know about. Run `./configure --help' for
91 details on some of the pertinent environment variables.
93 You can give `configure' initial values for configuration parameters
94 by setting variables in the command line or in the environment. Here
97 ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix

101 Compiling For Multiple Architectures
102 ====================================
104 You can compile the package for more than one kind of computer at the
105 same time, by placing the object files for each architecture in their
106 own directory. To do this, you must use a version of `make' that
107 supports the `VPATH' variable, such as GNU `make'. `cd' to the
108 directory where you want the object files and executables to go and run
109 the `configure' script. `configure' automatically checks for the
110 source code in the directory that `configure' is in and in `..'.
112 If you have to use a `make' that does not support the `VPATH'
113 variable, you have to compile the package for one architecture at a
114 time in the source code directory. After you have installed the
115 package for one architecture, use `make distclean' before reconfiguring
116 for another architecture.
121 By default, `make install' installs the package's commands under
122 `/usr/local/bin', include files under `/usr/local/include', etc. You
123 can specify an installation prefix other than `/usr/local' by giving
124 `configure' the option `--prefix=PREFIX'.
126 You can specify separate installation prefixes for
127 architecture-specific files and architecture-independent files. If you
128 pass the option `--exec-prefix=PREFIX' to `configure', the package uses
129 PREFIX as the prefix for installing programs and libraries.
130 Documentation and other data files still use the regular prefix.
132 In addition, if you use an unusual directory layout you can give
133 options like `--bindir=DIR' to specify different values for particular
134 kinds of files. Run `configure --help' for a list of the directories
135 you can set and what kinds of files go in them.
137 If the package supports it, you can cause programs to be installed
138 with an extra prefix or suffix on their names by giving `configure' the
139 option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
144 Some packages pay attention to `--enable-FEATURE' options to
145 `configure', where FEATURE indicates an optional part of the package.
146 They may also pay attention to `--with-PACKAGE' options, where PACKAGE
147 is something like `gnu-as' or `x' (for the X Window System). The
148 `README' should mention any `--enable-' and `--with-' options that the
151 For packages that use the X Window System, `configure' can usually
152 find the X include and library files automatically, but if it doesn't,
153 you can use the `configure' options `--x-includes=DIR' and
154 `--x-libraries=DIR' to specify their locations.
156 Specifying the System Type
157 ==========================
159 There may be some features `configure' cannot figure out automatically,
160 but needs to determine by the type of machine the package will run on.
161 Usually, assuming the package is built to be run on the _same_
162 architectures, `configure' can figure that out, but if it prints a
163 message saying it cannot guess the machine type, give it the
164 `--build=TYPE' option. TYPE can either be a short name for the system
165 type, such as `sun4', or a canonical name which has the form:
169 where SYSTEM can have one of these forms:
173 See the file `config.sub' for the possible values of each field. If
174 `config.sub' isn't included in this package, then this package doesn't
175 need to know the machine type.
177 If you are _building_ compiler tools for cross-compiling, you should
178 use the option `--target=TYPE' to select the type of system they will
181 If you want to _use_ a cross compiler, that generates code for a
182 platform different from the build platform, you should specify the
183 "host" platform (i.e., that on which the generated programs will
184 eventually be run) with `--host=TYPE'.
189 If you want to set default values for `configure' scripts to share, you
190 can create a site shell script called `config.site' that gives default
191 values for variables like `CC', `cache_file', and `prefix'.
192 `configure' looks for `PREFIX/share/config.site' if it exists, then
193 `PREFIX/etc/config.site' if it exists. Or, you can set the
194 `CONFIG_SITE' environment variable to the location of the site script.
195 A warning: not all `configure' scripts look for a site script.
200 Variables not defined in a site shell script can be set in the
201 environment passed to `configure'. However, some packages may run
202 configure again during the build, and the customized values of these
203 variables may be lost. In order to avoid this problem, you should set
204 them in the `configure' command line, using `VAR=value'. For example:
206 ./configure CC=/usr/local2/bin/gcc
208 causes the specified `gcc' to be used as the C compiler (unless it is
209 overridden in the site shell script). Here is a another example:
211 /bin/bash ./configure CONFIG_SHELL=/bin/bash
213 Here the `CONFIG_SHELL=/bin/bash' operand causes subsequent
214 configuration-related scripts to be executed by `/bin/bash'.
216 `configure' Invocation
217 ======================
219 `configure' recognizes the following options to control how it operates.
223 Print a summary of the options to `configure', and exit.
227 Print the version of Autoconf used to generate the `configure'
231 Enable the cache: use and save the results of the tests in FILE,
232 traditionally `config.cache'. FILE defaults to `/dev/null' to
237 Alias for `--cache-file=config.cache'.
242 Do not print messages saying which checks are being made. To
243 suppress all normal output, redirect it to `/dev/null' (any error
244 messages will still be shown).
247 Look for the package's source code in directory DIR. Usually
248 `configure' can determine that directory automatically.
250 `configure' also accepts some other, not widely useful, options. Run
251 `configure --help' for more details.
