4 :    
5 : anton 1.7 You need gcc version 2.0 or later to compile gforth.
6 : anton 1.1
7 : anton 1.5 First, type
8 : anton 1.3
9 : anton 1.8 ./configure
10 : anton 1.1
11 : anton 1.21 (see Section Configuration Options below for details).
12 :    
13 :     After configuration, type
14 :    
15 :     make
16 :    
17 :     Now you can check whether your shiny new Forth system works. Say
18 :    
19 : anton 1.30 make check
20 : anton 1.21
21 :     You can run some benchmarks with
22 :    
23 :     make bench
24 :    
25 :     and compare them with the results in Benchres and in the manual.
26 :    
27 :     If everything is all right, you may want to install gforth. Type
28 :    
29 :     make install
30 :    
31 :     For paper documentation, print gforth.ps (a Postscript file (300dpi
32 :     fonts, i.e., it works, but does not produce best quality on better
33 :     printers)), or say
34 :    
35 :     make gforth.dvi
36 :    
37 :     and print the resulting file gforth.dvi. You can also get the
38 :     documentation in HTML format by typing
39 :    
40 :     make html
41 :    
42 : anton 1.28 If you prefer plain ASCII documentation, you can
43 :    
44 :     make doc/gforth.txt
45 :    
46 :     or just concatenate the files gforth.info-* ('cat gforth.info-*' under
47 :     Unix); the result of the latter option is a little worse.
48 :    
49 :     You can find binary distributions, documentation in HTML and plain
50 :     text format and information on known installation problems at
51 :     http://www.complang.tuwien.ac.at/forth/gforth/.
52 : anton 1.21
53 :    
54 :     Configuration Options
55 :    
56 : anton 1.23 If you use GNU make, you can build in a directory different from the
57 :     source directory by changing to the build directory and invoking
58 :     configure thus:
59 : anton 1.21
60 :     $srcdir/configure
61 :    
62 : anton 1.23 where $srcdir is the source directory. (Note that we tested this only
63 : anton 1.21 for installation; i.e., if you want to hack the Gforth sources, you
64 :     should probably build in the source directory).
65 :    
66 : pazsan 1.4 configure has the following useful parameters:
67 : anton 1.9 --prefix=PREFIX install architecture-independent files in PREFIX
68 :     [default: /usr/local]
69 :     --exec-prefix=PREFIX install architecture-dependent files in PREFIX
70 :     [default: same as prefix]
71 : anton 1.8 --enable-force-reg Use explicit register declarations if they appear in
72 :     the machine.h file. This can cause a good speedup,
73 :     but also incorrect code with some gcc versions on
74 :     some processors (default disabled).
75 :     --help: tells you about other parameters.
76 : anton 1.1
77 : anton 1.21 The file Benchres shows which combination of the -enable options we
78 :     tried gave the best results for various machines.
79 :    
80 : anton 1.9 If you don't like the defaults for the installation directories, you
81 :     should override them already during configure. E.g., if you want to
82 :     install in the /gnu hierarchy instead of in the default /usr/local
83 : anton 1.15 hierarchy, say
84 : anton 1.5
85 : anton 1.9 ./configure --prefix=/gnu
86 : anton 1.2
87 : anton 1.17 Moreover, if your GCC is not called gcc (but, e.g., gcc-2.7.1), you
88 :     should say so during configuration. E.g.:
89 : pazsan 1.16
90 : anton 1.17 env CC=gcc-2.7.1 ./configure
91 : pazsan 1.16
92 : anton 1.17 You can also pass additional options to gcc in this way, e.g., if you
93 :     want to generate an a.out executable under Linux with gcc-2.7.0:
94 : anton 1.15
95 : anton 1.17 env "CC=gcc -b i486-linuxaout -V 2.7.0" ./configure
96 : anton 1.15
97 : anton 1.22 You can change the sizes of the various areas used in the default
98 :     image `gforth.fi' by passing the appropriate Gforth command line
99 :     options in the FORTHSIZES environment variable:
100 :    
101 : anton 1.26 env "FORTHSIZES=--dictionary-size=256k --data-stack-size=16k --fp-stack-size=15872b --return-stack-size=15k --locals-stack-size=14848b" ./configure
102 : anton 1.22
103 :     The line above reaffirms the default sizes. Note that the locals
104 :     stack area is also used as input buffer stack.
105 : anton 1.17
106 : anton 1.24 If C's "long long" do not work properly on your machine (i.e., if the
107 :     tests involving double-cell numbers fail), you can build Gforth such
108 :     that it does not use "long long":
109 :    
110 :     env ac_cv_sizeof_long_long=0 ./configure
111 :    
112 :    
113 : anton 1.31 Cross-Installation
114 : anton 1.24
115 : anton 1.31 You need a cross-compilation toolchain for your target including gcc
116 :     (2.0 or later).
117 :    
118 :     The first step in cross-installation is the cross-configuration. A
119 :     few tests made by the configure script do not work in a
120 : anton 1.24 cross-compilation situation. You have to provide the results of these
121 :     tests by hand. E.g., if you compile for a 386 architecture processor:
122 :    
123 : anton 1.32 env ac_cv_sizeof_char_p=4 ac_cv_sizeof_char=1 ac_cv_sizeof_short=2 ac_cv_sizeof_int=4 ac_cv_sizeof_long=4 ac_cv_sizeof_long_long=8 ac_cv_sizeof_intptr_t=4 ac_cv_sizeof_int128_t=0 ac_cv_c_bigendian=no ./configure
124 : anton 1.24
125 :     The ac_cv_sizeof_... variables give the sizes of various C types;
126 :     ac_cv_sizeof_char_p is the same as "sizeof(char*)" in C code. The
127 :     ac_cv_c_bigendian variable gives the byte order.
128 : anton 1.31
129 :     After the cross-configuration you type
130 :    
131 :     make gforths
132 :    
133 :     This produces the gforth engines for the target.
134 :    
135 :     The next step is to transfer everything to the target; on the target,
136 :     you do
137 :    
138 :     make
139 :    
140 :     to complete building gforth. If you do not have a make on the target,
141 :     run
142 :    
143 :     make -n
144 :    
145 :     on the host; manually execute on the target the last command output by
146 :     "make -n" (GFORTHD=...); the other commands output by "make -n" are
147 :     not necessary unless you have changed the Gforth sources. You can
148 :     then check and benchmark Gforth with
149 :    
150 :     make check
151 :     make bench
152 :    
153 :     or equivalent. Finally, perform
154 :    
155 :     make install
156 :    
157 :     or the equivalent commands on the target.
158 : anton 1.24
159 :    
160 : anton 1.17 Preloading installation-specific code
161 :    
162 :     If you want to have some installation-specific files loaded when
163 :     Gforth starts (e.g., an assembler for your processor), put commands
164 : anton 1.28 for loading them into /usr/local/share/gforth/site-forth/siteinit.fs
165 : anton 1.17 (if the commands work for all architectures) or
166 : anton 1.28 /usr/local/lib/gforth/site-forth/siteinit.fs (for
167 : anton 1.17 architecture-specific commands);
168 : anton 1.28 /usr/local/lib/gforth/site-forth/siteinit.fs takes precedence if both
169 : anton 1.17 files are present (unless you change the search path). The file names
170 :     given above are the defaults; if you have changed the prefix, you have
171 :     to replace "/usr/local" in these names with your prefix.
172 :    
173 :     By default, the installation procedure creates an empty
174 : anton 1.28 /usr/local/share/gforth/site-forth/siteinit.fs if there is no such
175 : anton 1.17 file.
176 :    
177 : anton 1.28 If you change the siteinit.fs file, you should run "make install"
178 : anton 1.17 again for the changes to take effect (Actually, the part of "make
179 :     install" starting with "rm gforth.fi" is sufficient).
180 :    
181 :    
182 : anton 1.12 Multiple Versions and Deinstallation
183 :    
184 :     Several versions of Gforth can be installed and used at the same
185 :     time. Version `foo' can be invoked with `gforth-foo'. We recommend to
186 :     keep the old version for some time after a new one has been installed.
187 : anton 1.10
188 : anton 1.12 You can deinstall this version of Gforth with 'make uninstall' and
189 :     version foo with 'make uninstall VERSION=foo'. 'make uninstall' also
190 :     tells you how to uninstall Gforth completely.
191 : crook 1.29
192 :    
193 :     Installing Info Files
194 :    
195 :     Info is the GNU project on-line documentation format. You can read
196 :     info files either from within Emacs (Ctrl-h i) or using the
197 :     stand-alone Info reader, 'info'.
198 :    
199 :     If you use the default install root of '/usr/local' then the info
200 :     files will be installed in '/usr/local/info'.
201 :    
202 :     Many GNU/Linux distributions are set up to put all of their
203 :     documentation in '/usr/info', in which case you might have to do a
204 :     couple of things to get your environment set up to accommodate files
205 :     in both areas:
206 :    
207 :     1. Add an INFOPATH environment variable. The easiest place to do
208 :     this is '/etc/profile', right next to PATH and MANPATH:
209 :    
210 :     INFOPATH=/usr/local/info:/usr/info
211 :    
212 :     2. Create a file called 'dir' in 'usr/local/info'. Use the file
213 :     '/usr/info/dir' as a template. You can add the line for gforth
214 :     manually, or use '/sbin/install-info' (man install-info for details).
