added more.fs for people with old terminals.
WORDS and SEE now now respect the terminal size.
a lot of reordering in the Makefile, approaching the GNU standards.
factored NAME>STRING out of many words.
use AC_DECL_SYS_SIGLIST test in configure.in.
removed emitcounter (it was not used anyway).
SYSTEM now unpreps and repreps the terminal.
fixed byg in prims2x.fs.
added NEEDS, ?CSP, !CSP.
rewrote ALIAS?.
1: You need gcc version 2.0 or later to compile gforth.
2:
3: First, type
4:
5: ./configure
6:
7: configure has the following useful parameters:
8: --prefix=PREFIX install architecture-independent files in PREFIX
9: [default: /usr/local]
10: --exec-prefix=PREFIX install architecture-dependent files in PREFIX
11: [default: same as prefix]
12: --enable-force-reg Use explicit register declarations if they appear in
13: the machine.h file. This can cause a good speedup,
14: but also incorrect code with some gcc versions on
15: some processors (default disabled).
16: --enable-direct-threaded Force direct threading. This may not work on
17: some machines and may cause slowdown on others.
18: (default processor-dependent)
19: --enable-indirect-threaded Force indirect threading. This can cause a
20: slowdown on some machines.
21: (default processor-dependent)
22: --with-debug specifies option -g to compile with debug info (default)
23: --without-debug omits the -g switch and creates smaller images on
24: machines where strip has problems with gcc style
25: debugging informations.
26: --help: tells you about other parameters.
27:
28: If you don't like the defaults for the installation directories, you
29: should override them already during configure. E.g., if you want to
30: install in the /gnu hierarchy instead of in the default /usr/local
31: hierarchy, say
32:
33: ./configure --prefix=/gnu
34:
35: Moreover, if your GCC is not called gcc (but, e.g., gcc-2.7.1), you
36: should say so during configuration. E.g.:
37:
38: env CC=gcc-2.7.1 ./configure
39:
40: You can also pass additional options to gcc in this way, e.g., if you
41: want to generate an a.out executable under Linux with gcc-2.7.0:
42:
43: env "CC=gcc -b i486-linuxaout -V 2.7.0" ./configure
44:
45: After, configuration, type
46:
47: make
48:
49: Now you can check whether your shiny new Forth system works. Say
50:
51: make test
52:
53: You can run some benchmarks with
54:
55: make bench
56:
57: and compare them with the results in Benchres and in the manual.
58:
59: If everything is all right, you may want to install gforth. Type
60:
61: make install
62:
63: You have to make an entry in the info directory file manually.
64:
65: For paper documentation, print gforth.ps (a Postscript file (300dpi
66: fonts, i.e., it works, but does not produce best quality on better
67: printers)), or say
68:
69: make gforth.dvi
70:
71: and print the resulting file gforth.dvi. You can also get the
72: documentation in HTML format by typing
73:
74: make html
75:
76: If you prefer plain ASCII documentation, just concatenate the files
77: gforth.info-* ('cat gforth.info-*' under Unix).
78:
79: Preloading installation-specific code
80:
81: If you want to have some installation-specific files loaded when
82: Gforth starts (e.g., an assembler for your processor), put commands
83: for loading them into /usr/local/share/gforth/site-forth/site-init.fs
84: (if the commands work for all architectures) or
85: /usr/local/lib/gforth/site-forth/site-init.fs (for
86: architecture-specific commands);
87: /usr/local/lib/gforth/site-forth/site-init.fs takes precedence if both
88: files are present (unless you change the search path). The file names
89: given above are the defaults; if you have changed the prefix, you have
90: to replace "/usr/local" in these names with your prefix.
91:
92: By default, the installation procedure creates an empty
93: /usr/local/share/gforth/site-forth/site-init.fs if there is no such
94: file.
95:
96: If you change the site-init.fs file, you should run "make install"
97: again for the changes to take effect (Actually, the part of "make
98: install" starting with "rm gforth.fi" is sufficient).
99:
100:
101: Multiple Versions and Deinstallation
102:
103: Several versions of Gforth can be installed and used at the same
104: time. Version `foo' can be invoked with `gforth-foo'. We recommend to
105: keep the old version for some time after a new one has been installed.
106:
107: You can deinstall this version of Gforth with 'make uninstall' and
108: version foo with 'make uninstall VERSION=foo'. 'make uninstall' also
109: tells you how to uninstall Gforth completely.
110:
111:
112: A Possible Problem
113:
114: You need to read this only if you see a message like
115:
116: "gforth: Cannot load nonrelocatable image (compiled for address 0x1234) at address 0x5678
117: The Gforth installer should look into the INSTALL file"
118:
119: Gforth supports both relocatable and fixed-address images. If you load
120: normal Forth code and save the image, you get a fixed-address
121: image. Producing a relocatable image is more difficult.
122:
123: Therefore, Gforth has only a relocatable image of the kernel
124: (kernal.fi), which is powerful enough to load the rest of
125: Gforth. However, loading the rest takes a noticable amount of time. To
126: avoid this delay (which would occur on every startup), the
127: installation procedure produces an image fixed at an address
128: determined at the Gforth run that produced the image. This
129: fixed-address image is loaded by default. On most OSs this works,
130: because the first chunk of memory is always allocated at the same
131: address. If the address changes, you get the message above.
132:
133: An image address change can be caused by a change of the gforth
134: executable, or by a change (upgrade) of the OS; in these cases you
135: just have to rebuild and reinstall the fixed address image with
136:
137: rm gforth.fi; make gforth.fi; make install
138:
139: If you get such a message with a different address in place of the
140: 0x5678 each time you try to start gforth, you cannot use fixed-address
141: images on your OS. In this case, send us a message so that we start
142: searching for a comfortable solution to this problem. In the
143: meantime, start gforth with
144:
145: gforth -i kernal.fi startup.fs
