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 Coop threads are not yet thoroughly tested; once they are, they will
77 be enabled by default. The interaction with blocking I/O is pretty ad
78 hoc at the moment. In our experience, bugs in the thread support do
79 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 file would be
106 `/home/jimb/guile-snap/INSTALL'). Then you might say:
107
108 export GUILE_LOAD_PATH=/home/jimb/guile-snap
109
110 if you're using Bash or any other Bourne shell variant, or
111
112 setenv GUILE_LOAD_PATH /home/jimb/guile-snap
113
114 if you're using CSH or one of its variants.
115
116 If you built Guile in a separate directory from the source tree, then
117 you'll need to include your build directory in the GUILE_LOAD_PATH as
118 well. For example, if you built in a subdirectory of the source tree
119 called `pentium', you might say:
120
121 export GUILE_LOAD_PATH=/home/jimb/guile-snap:/home/jimb/guile-snap/pentium
122
123
124 Building a Statically Linked Guile ========================================
125
126 Sometimes it's useful to build a statically-linked version of the
127 Guile executable. It's helpful in debugging, and for producing
128 stand-alone executables for distribution to machines you don't
129 control.
130
131 To do this, set the LDFLAGS environment variable to `-static' before
132 you configure, or before you run the `make' command to build the
133 executable.
134
135
136 Generic Instructions for Building Auto-Configured Packages ================
137
138 To compile this package:
139
140 1. Configure the package for your system. In the directory that this
141 file is in, type `./configure'. If you're using `csh' on an old
142 version of System V, you might need to type `sh configure' instead to
143 prevent `csh' from trying to execute `configure' itself.
144
145 The `configure' shell script attempts to guess correct values for
146 various system-dependent variables used during compilation, and
147 creates the Makefile(s) (one in each subdirectory of the source
148 directory). In some packages it creates a C header file containing
149 system-dependent definitions. It also creates a file `config.status'
150 that you can run in the future to recreate the current configuration.
151 Running `configure' takes a minute or two.
152
153 To compile the package in a different directory from the one
154 containing the source code, you must use GNU make. `cd' to the
155 directory where you want the object files and executables to go and
156 run `configure' with the option `--srcdir=DIR', where DIR is the
157 directory that contains the source code. Using this option is
158 actually unnecessary if the source code is in the parent directory of
159 the one in which you are compiling; `configure' automatically checks
160 for the source code in `..' if it does not find it in the current
161 directory.
162
163 By default, `make install' will install the package's files in
164 /usr/local/bin, /usr/local/lib, /usr/local/man, etc. You can specify
165 an installation prefix other than /usr/local by giving `configure' the
166 option `--prefix=PATH'. Alternately, you can do so by changing the
167 `prefix' variable in the Makefile that `configure' creates (the
168 Makefile in the top-level directory, if the package contains
169 subdirectories).
170
171 You can specify separate installation prefixes for machine-specific
172 files and machine-independent files. If you give `configure' the
173 option `--exec_prefix=PATH', the package will use PATH as the prefix
174 for installing programs and libraries. Normally, all files are
175 installed using the same prefix.
176
177 `configure' ignores any other arguments that you give it.
178
179 If your system requires unusual options for compilation or linking
180 that `configure' doesn't know about, you can give `configure' initial
181 values for some variables by setting them in the environment. In
182 Bourne-compatible shells, you can do that on the command line like
183 this:
184 CC='gcc -traditional' DEFS=-D_POSIX_SOURCE ./configure
185
186 The `make' variables that you might want to override with environment
187 variables when running `configure' are:
188
189 (For these variables, any value given in the environment overrides the
190 value that `configure' would choose:)
191 CC C compiler program.
192 Default is `cc', or `gcc' if `gcc' is in your PATH.
193 INSTALL Program to use to install files.
194 Default is `install' if you have it, `cp' otherwise.
195 INCLUDEDIR Directory for `configure' to search for include files.
196 Default is /usr/include.
197
198 (For these variables, any value given in the environment is added to
199 the value that `configure' chooses:)
200 DEFS Configuration options, in the form '-Dfoo -Dbar ...'
201 LIBS Libraries to link with, in the form '-lfoo -lbar ...'
202
203 If you need to do unusual things to compile the package, we encourage
204 you to teach `configure' how to do them and mail the diffs to the
205 address given in the README so we can include them in the next
206 release.
207
208 2. Type `make' to compile the package.
209
210 3. Type `make install' to install programs, data files, and
211 documentation.
212
213 4. You can remove the program binaries and object files from the
214 source directory by typing `make clean'. To also remove the
215 Makefile(s), the header file containing system-dependent definitions
216 (if the package uses one), and `config.status' (all the files that
217 `configure' created), type `make distclean'.
218
219 The file `configure.in' is used as a template to create `configure' by
220 a program called `autoconf'. You will only need it if you want to
221 regenerate `configure' using a newer version of `autoconf'.
