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