1 Brief Installation Instructions ===========================================
2
3 To build Guile on unix, there are two basic steps:
4
5 1. Type "./configure", to configure the package for your system.
6 2. Type "make", to build the package.
7
8 Generic instructions for configuring and compiling GNU distributions
9 are included below.
10
11
12 Special Instructions For Some Systems =====================================
13
14 We would like Guile to build on all systems using the simple
15 instructions above, but it seems that a few systems still need special
16 treatment. If you can send us fixes for these problems, we'd be
17 grateful.
18
19 SunOS 4.1: Guile's shared library support seems to be confused, but
20 hey; shared libraries are confusing. You may need to configure
21 Guile with a command like:
22 ./configure --disable-shared
23 For more information on `--disable-shared', see below, "Flags
24 Accepted by Configure".
25
26 HP/UX: GCC 2.7.2 (and maybe other versions) have trouble creating
27 shared libraries if they depend on any non-shared libraries. GCC
28 seems to have other problems as well. To work around this, we
29 suggest you configure Guile to use the system's C compiler:
30 CC=cc ./configure
31
32 NetBSD: Perry Metzger says, "Guile will build under NetBSD only using
33 gmake -- the native make will not work. (gmake is in our package
34 system, so this will not be a problem when we packagize 1.3.)"
35
36 What You Get ==============================================================
37
38 The `configure' script examines your system, and adapts Guile to
39 compile and run on it.
40
41 The `make' command builds several things:
42 - An executable file `guile/guile', which is an interactive shell for
43 talking with the Guile Scheme interpreter.
44 - An object library `libguile/.libs/libguile.a', containing the Guile Scheme
45 interpreter, ready to be linked into your programs.
46
47 To install Guile, type `make install'. This installs the executable
48 and libraries mentioned above, as well as Guile's header files and
49 Scheme libraries.
50
51 Make also builds shared libraries, on systems that support them.
52 Because of the nature of shared libraries, before linking against
53 them, you should probably install them; `make install' takes care of
54 this.
55
56
57 Flags Accepted by Configure ===============================================
58
59 If you run the configure script with no arguments, it should examine
60 your system and set things up appropriately. However, there are a few
61 switches specific to Guile you may find useful in some circumstances.
62
63 --enable-maintainer-mode --- If you have automake, autoconf, and
64 libtool installed on your system, this switch causes configure to
65 generate Makefiles which know how to automatically regenerate
66 configure scripts, makefiles, and headers, when they are out of date.
67 The README file says which versions of those tools you will need.
68
69 --with-threads --- Build a Guile executable and library that supports
70 cooperative threading. If you use this switch, Guile will also build
71 and install the QuickThreads non-preemptive threading library,
72 libqt.a, which you will need to link into your programs after
73 libguile.a. That is, you should pass the switches -lguile -qt to your
74 linker.
75
76 Cooperative threads are not yet thoroughly tested; once they are, they
77 will be enabled by default. The interaction with blocking I/O is
78 pretty ad hoc at the moment. In our experience, bugs in the thread
79 support do not affect you if you don't actually use threads.
80
81 --enable-dynamic-linking --- Build a Guile executable and library
82 providing Scheme functions which can load a shared library and
83 initialize it, perhaps thereby adding new functions to Guile. This
84 feature is enabled by default; you only need to use this option (as
85 `--enable-dynamic-linking=no') if you want to build a Guile which does
86 not support dynamic linking.
87
88 This option has no effect on systems that do not support shared
89 libraries.
90
91 --disable-shared --- Do not build shared libraries. Normally, Guile
92 will build shared libraries if your system supports them. Guile
93 always builds static libraries.
94
95
96 Using Guile Without Installing It =========================================
97
98 If you want to run Guile without installing it, set the environment
99 variable `GUILE_LOAD_PATH' to a colon-separated list of directories,
100 including the directory containing this INSTALL file. If you used a
101 separate build directory, you'll need to include the build directory
102 in the path as well.
103
104 For example, suppose the Guile distribution unpacked into a directory
105 called `/home/jimb/guile-snap' (so the full name of this INSTALL file
106 would be `/home/jimb/guile-snap/INSTALL'). Then you might say, if
107 you're using Bash or any other Bourne shell variant,
108
109 export GUILE_LOAD_PATH=/home/jimb/guile-snap
110
111 or if you're using CSH or one of its variants:
112
113 setenv GUILE_LOAD_PATH /home/jimb/guile-snap
114
115
116 Building a Statically Linked Guile ========================================
117
118 Sometimes it's useful to build a statically-linked version of the
119 Guile executable. It's helpful in debugging, and for producing
120 stand-alone executables for distribution to machines you don't
121 control.
122
123 To do this, set the LDFLAGS environment variable to `-static' before
124 you configure, or before you run the `make' command to build the
125 executable.
126
127
128 Generic Instructions for Building Auto-Configured Packages ================
129
130 To compile this package:
131
132 1. Configure the package for your system. In the directory that this
133 file is in, type `./configure'. If you're using `csh' on an old
134 version of System V, you might need to type `sh configure' instead to
135 prevent `csh' from trying to execute `configure' itself.
136
137 The `configure' shell script attempts to guess correct values for
138 various system-dependent variables used during compilation, and
139 creates the Makefile(s) (one in each subdirectory of the source
140 directory). In some packages it creates a C header file containing
141 system-dependent definitions. It also creates a file `config.status'
142 that you can run in the future to recreate the current configuration.
143 Running `configure' takes a minute or two.
144
145 To compile the package in a different directory from the one
146 containing the source code, you must use GNU make. `cd' to the
147 directory where you want the object files and executables to go and
148 run `configure' with the option `--srcdir=DIR', where DIR is the
149 directory that contains the source code. Using this option is
150 actually unnecessary if the source code is in the parent directory of
151 the one in which you are compiling; `configure' automatically checks
152 for the source code in `..' if it does not find it in the current
153 directory.
154
155 By default, `make install' will install the package's files in
156 /usr/local/bin, /usr/local/lib, /usr/local/man, etc. You can specify
157 an installation prefix other than /usr/local by giving `configure' the
158 option `--prefix=PATH'. Alternately, you can do so by changing the
159 `prefix' variable in the Makefile that `configure' creates (the
160 Makefile in the top-level directory, if the package contains
161 subdirectories).
162
163 You can specify separate installation prefixes for machine-specific
164 files and machine-independent files. If you give `configure' the
165 option `--exec_prefix=PATH', the package will use PATH as the prefix
166 for installing programs and libraries. Normally, all files are
167 installed using the same prefix.
168
169 `configure' ignores any other arguments that you give it.
170
171 If your system requires unusual options for compilation or linking
172 that `configure' doesn't know about, you can give `configure' initial
173 values for some variables by setting them in the environment. In
174 Bourne-compatible shells, you can do that on the command line like
175 this:
176 CC='gcc -traditional' DEFS=-D_POSIX_SOURCE ./configure
177
178 The `make' variables that you might want to override with environment
179 variables when running `configure' are:
180
181 (For these variables, any value given in the environment overrides the
182 value that `configure' would choose:)
183 CC C compiler program.
184 Default is `cc', or `gcc' if `gcc' is in your PATH.
185 INSTALL Program to use to install files.
186 Default is `install' if you have it, `cp' otherwise.
187 INCLUDEDIR Directory for `configure' to search for include files.
188 Default is /usr/include.
189
190 (For these variables, any value given in the environment is added to
191 the value that `configure' chooses:)
192 DEFS Configuration options, in the form '-Dfoo -Dbar ...'
193 LIBS Libraries to link with, in the form '-lfoo -lbar ...'
194
195 If you need to do unusual things to compile the package, we encourage
196 you to teach `configure' how to do them and mail the diffs to the
197 address given in the README so we can include them in the next
198 release.
199
200 2. Type `make' to compile the package.
201
202 3. Type `make install' to install programs, data files, and
203 documentation.
204
205 4. You can remove the program binaries and object files from the
206 source directory by typing `make clean'. To also remove the
207 Makefile(s), the header file containing system-dependent definitions
208 (if the package uses one), and `config.status' (all the files that
209 `configure' created), type `make distclean'.
210
211 The file `configure.in' is used as a template to create `configure' by
212 a program called `autoconf'. You will only need it if you want to
213 regenerate `configure' using a newer version of `autoconf'.
