3: You need DJ Delorie's port of GCC to DOS (DJGPP 2.0) to compile
4: Gforth. DJGPP provides a DPMI client that allows to use the 32-bit
5: features of the 80386, but on the other hand it requires at least a
6: 386. A DPMI host is also part of the DJGPP 2.0 package, this is
7: required if you don't have a DPMI host yourself (Windows/OS/2/Linux
8: DOS-box, Quemm or others).
12: You need EMX 0.9c to compile Gforth. The EMX package provides all
13: necessary Unix-like tools, tty and signal handling.
15: If you don't want to install the DJGPP or EMX package (quite large),
16: look for a binary distribution of Gforth for DOS or OS/2. You also
17: must have a version of GNU make, because DOS/OS/2 make programs are
18: likely to have problems with the Makefile. If you want to change
19: Gforth, you may need GNU m4, too. Because DJGPP provides use of long
20: filenames under Windows 95, you should unpack the gforth package with
21: a Windows-95-aware archiver (those from DJGPP or the Cygnus
22: Win32-package come in mind), because otherwise gforth will not find
23: the necessary files. With MS-DOS versions prior 7.0 or DR-DOS, these
24: names are cut due to the 8.3 rule. This might confuse DJGPP 2.0's
25: make, you could use DJGPP 1.x's make instead. Gforth 0.2.0 hasn't been
26: compiled with a MS-DOS prior 7.0.
28: Compiling under DOS or OS/2 has a number of quirks, and if it doesn't
29: compile out of the box, you should know what you do. I therefore
30: discourage unexperienced users to compile gforth themselfes. There's a
31: binary package for it anyway.
33: If you don't bother and want to make it yourself, type
37: configure has the following useful parameters:
38: --enable-force-reg Use explicit register declarations if they appear in
39: the machine.h file. This can cause a good speedup,
40: but also incorrect code with some gcc versions on
41: some processors (default disabled).
42: --enable-direct-threaded Force direct threading. This may not work on
43: some machines and may cause slowdown on others.
44: (default disabled)
45: --enable-indirect-threaded Force indirect threading. This can cause a
46: slowdown on some machines.
47: (default enabled)
49: After covering all inconveniences, type
53: Now you can check whether your shiny new Forth system works. Say
55: make test
57: You can run some benchmarks with
59: make bench
61: and compare them with the results in Benchres and in the manual.
63: Don't try to do "make install", it won't work, either. It is not possible to
64: "make dist" or "make bindist", too, because of the limitations of DOS
65: command lines.
67: Add the following entry to your Autoexec.bat:
69: SET GFORTHPATH=<your gforth source directory>;.
71: Use / instead of \ in your gforth source directory. Gforth now uses
72: ';' as path separator, so you won't have problems with DOS pathes that
73: may contain ':', which is the default path separator in Unix.
75: For paper documentation, print gforth.ps (a Postscript file (300dpi
76: fonts, i.e., it works, but does not produce best quality on better
77: printers)), or say
79: make gforth.dvi
81: and print the resulting file gforth.dvi (you need TeX for that! But
82: with TeX you can print it even if you don't have a Postscript printer
83: nor Ghostscript). You could be able to make a HTML version of the
84: document, but AFAIK there is no texi2html for DOS available, as there
85: is no perl available.
