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 Flags Accepted by Configure ===============================================
37
38 If you run the configure script with no arguments, it should examine
39 your system and set things up appropriately. However, there are a few
40 switches specific to Guile you may find useful in some circumstances.
41
42 --enable-maintainer-mode --- If you have automake, autoconf, and
43 libtool installed on your system, this switch causes configure to
44 generate Makefiles which know how to automatically regenerate
45 configure scripts, makefiles, and headers, when they are out of date.
46 The README file says which versions of those tools you will need.
47
48 --with-threads --- Build a Guile executable and library that supports
49 cooperative threading. If you use this switch, Guile will also build
50 and install the QuickThreads non-preemptive threading library,
51 libqthreads, which you will need to link into your programs after
52 libguile. When you use `guile-config', you will pick up all
53 neccessary linker flags automatically.
54
55 Cooperative threads are not yet thoroughly tested; once they are, they
56 will be enabled by default. The interaction with blocking I/O is
57 pretty ad hoc at the moment. In our experience, bugs in the thread
58 support do not affect you if you don't actually use threads.
59
60 --with-modules --- Guile can dynamically load `plugin modules' during
61 runtime, using facilities provided by libtool. Not all platforms
62 support this, however. On these platforms, you can statically link
63 the plugin modules into libguile when Guile itself is build. XXX -
64 how does one specify the modules?
65
66 --disable-shared --- Do not build shared libraries. Normally, Guile
67 will build shared libraries if your system supports them. Guile
68 always builds static libraries.
69
70 --enable-debug-freelist --- Enable freelist debugging.
71
72 This enables a debugging version of SCM_NEWCELL(), and also registers
73 an extra primitive, the setter `gc-set-debug-check-freelist!'.
74
75 Configure with the --enable-debug-freelist option to enable
76 the gc-set-debug-check-freelist! primitive, and then use:
77
78 (gc-set-debug-check-freelist! #t) # turn on checking of the freelist
79 (gc-set-debug-check-freelist! #f) # turn off checking
80
81 Checking of the freelist forces a traversal of the freelist and
82 a garbage collection before each allocation of a cell. This can
83 slow down the interpreter dramatically, so the setter should be used to
84 turn on this extra processing only when necessary.
85
86 --enable-debug-malloc --- Enable malloc debugging.
87
88 Include code for debugging of calls to scm_must_malloc/realloc/free.
89
90 Checks that
91
92 1. objects freed by scm_must_free has been mallocated by scm_must_malloc
93 2. objects reallocated by scm_must_realloc has been allocated by
94 scm_must_malloc
95 3. reallocated objects are reallocated with the same what string
96
97 But, most importantly, it records the number of allocated objects of
98 each kind. This is useful when searching for memory leaks.
99
100 A Guile compiled with this option provides the primitive
101 `malloc-stats' which returns an alist with pairs of kind and the
102 number of objects of that kind.
103
104 --disable-arrays --- omit array and uniform array support
105 --disable-posix --- omit posix interfaces
106 --disable-networking --- omit networking interfaces
107 --disable-regex --- omit regular expression interfaces
108
109 Using Guile Without Installing It =========================================
110
111 If you want to run Guile without installing it, set the environment
112 variable `GUILE_LOAD_PATH' to a colon-separated list of directories,
113 including the directory containing this INSTALL file. If you used a
114 separate build directory, you'll need to include the build directory
115 in the path as well.
116
117 For example, suppose the Guile distribution unpacked into a directory
118 called `/home/jimb/guile-snap' (so the full name of this INSTALL file
119 would be `/home/jimb/guile-snap/INSTALL'). Then you might say, if
120 you're using Bash or any other Bourne shell variant,
121
122 export GUILE_LOAD_PATH=/home/jimb/guile-snap
123
124 or if you're using CSH or one of its variants:
125
126 setenv GUILE_LOAD_PATH /home/jimb/guile-snap
127
128
129 Generic Instructions for Building Auto-Configured Packages ================
130
131 To compile this package:
132
133 1. Configure the package for your system. In the directory that this
134 file is in, type `./configure'. If you're using `csh' on an old
135 version of System V, you might need to type `sh configure' instead to
136 prevent `csh' from trying to execute `configure' itself.
137
138 The `configure' shell script attempts to guess correct values for
139 various system-dependent variables used during compilation, and
140 creates the Makefile(s) (one in each subdirectory of the source
141 directory). In some packages it creates a C header file containing
142 system-dependent definitions. It also creates a file `config.status'
143 that you can run in the future to recreate the current configuration.
144 Running `configure' takes a minute or two.
145
146 To compile the package in a different directory from the one
147 containing the source code, you must use GNU make. `cd' to the
148 directory where you want the object files and executables to go and
149 run `configure' with the option `--srcdir=DIR', where DIR is the
150 directory that contains the source code. Using this option is
151 actually unnecessary if the source code is in the parent directory of
152 the one in which you are compiling; `configure' automatically checks
153 for the source code in `..' if it does not find it in the current
154 directory.
155
156 By default, `make install' will install the package's files in
157 /usr/local/bin, /usr/local/lib, /usr/local/man, etc. You can specify
158 an installation prefix other than /usr/local by giving `configure' the
159 option `--prefix=PATH'. Alternately, you can do so by changing the
160 `prefix' variable in the Makefile that `configure' creates (the
161 Makefile in the top-level directory, if the package contains
162 subdirectories).
163
164 You can specify separate installation prefixes for machine-specific
165 files and machine-independent files. If you give `configure' the
166 option `--exec_prefix=PATH', the package will use PATH as the prefix
167 for installing programs and libraries. Normally, all files are
168 installed using the same prefix.
169
170 `configure' ignores any other arguments that you give it.
171
172 If your system requires unusual options for compilation or linking
173 that `configure' doesn't know about, you can give `configure' initial
174 values for some variables by setting them in the environment. In
175 Bourne-compatible shells, you can do that on the command line like
176 this:
177 CC='gcc -traditional' DEFS=-D_POSIX_SOURCE ./configure
178
179 The `make' variables that you might want to override with environment
180 variables when running `configure' are:
181
182 (For these variables, any value given in the environment overrides the
183 value that `configure' would choose:)
184 CC C compiler program.
185 Default is `cc', or `gcc' if `gcc' is in your PATH.
186 INSTALL Program to use to install files.
187 Default is `install' if you have it, `cp' otherwise.
188 INCLUDEDIR Directory for `configure' to search for include files.
189 Default is /usr/include.
190
191 (For these variables, any value given in the environment is added to
192 the value that `configure' chooses:)
193 DEFS Configuration options, in the form '-Dfoo -Dbar ...'
194 LIBS Libraries to link with, in the form '-lfoo -lbar ...'
195
196 If you need to do unusual things to compile the package, we encourage
197 you to teach `configure' how to do them and mail the diffs to the
198 address given in the README so we can include them in the next
199 release.
200
201 2. Type `make' to compile the package.
202
203 3. Type `make install' to install programs, data files, and
204 documentation.
205
206 4. You can remove the program binaries and object files from the
207 source directory by typing `make clean'. To also remove the
208 Makefile(s), the header file containing system-dependent definitions
209 (if the package uses one), and `config.status' (all the files that
210 `configure' created), type `make distclean'.
211
212 The file `configure.in' is used as a template to create `configure' by
213 a program called `autoconf'. You will only need it if you want to
214 regenerate `configure' using a newer version of `autoconf'.
