7: You need DJ Delorie's port of GCC to DOS (DJGPP 2.0) to compile
8: Gforth. DJGPP provides a DPMI client that allows to use the 32-bit
9: features of the 80386, but on the other hand it requires at least a
10: 386. A DPMI host is also part of the DJGPP 2.0 package, this is
11: required if you don't have a DPMI host yourself (Windows/OS/2/Linux
12: DOS-box, Quemm or others).
14: First run
18: config has the following useful parameters:
19: --enable-force-reg Use explicit register declarations if they appear in
20: the machine.h file. This can cause a good speedup,
21: but also incorrect code with some gcc versions on
22: some processors (default disabled).
23: --enable-direct-threaded Force direct threading. This may not work on
24: some machines and may cause slowdown on others.
25: (default disabled)
26: --enable-indirect-threaded Force indirect threading. This can cause a
27: slowdown on some machines.
28: (default enabled)
32: You need EMX 0.9c to compile Gforth. The EMX package provides all
33: necessary Unix-like tools, tty and signal handling.
35: Windows 95/Windows NT:
37: You need the Cygnus Win32 package. This package currently is only in
38: beta test, so expect bugs and quirks.
40: If you don't want to install the DJGPP, CYGWIN32 or EMX package (quite
41: large), look for a binary distribution of Gforth for DOS, Win32 or
44: You also must have a version of GNU make, because DOS/Win32/OS/2 make
45: programs are likely to have problems with the Makefile. If you want to
46: change Gforth, you may need GNU m4, too. Because DJGPP provides some
47: use of long filenames under Windows 95, you should unpack the gforth
48: package with a Windows-95-aware archiver (those from DJGPP or the
49: Cygnus Win32-package come in mind), because otherwise gforth will not
50: find the necessary files. With MS-DOS versions prior 7.0 or DR-DOS,
51: these names are cut due to the 8.3 rule. This might confuse DJGPP
52: 2.0's make, you could use DJGPP 1.x's make instead. Gforth 0.4.0
53: hasn't been compiled with a MS-DOS prior 7.0.
55: Compiling under DOS or OS/2 has a number of quirks, and if it doesn't
56: compile out of the box, you should know what you do. I therefore
57: discourage unexperienced users to compile gforth themselves. There's a
58: binary package for it anyway.
60: Compiling using CygWin32 works a bit better, but there are still
61: quirks. The package allows to "mount" Windows directories under
62: typical unix locations. E.g. I installed the package in E:\cygnus, and
63: then I mount /usr, /usr/local and /bin with
65: ./mount e:/cygnus /usr
66: ./mount e:/cygnus/H-i386-cygwin32 /usr/local
67: ./mount e:/cygnus/H-i386-cygwin32/bin /bin
69: once. Each time I start CygWin32's bash, I set up the following variables:
71: export TMPDIR=/usr/tmp
72: export COMPILER_PATH=/usr/local/lib/gcc-lib/i386-cygwin32/cygnus-2.7.2-970404
73: export LIBRARY_PATH="/usr/lib;/usr/local/lib"
74: export C_INCLUDE_PATH=/usr/local/i386-cygwin32/include
75: export GCC_DEFAULT_OPTIONS="-specs=$COMPILER_PATH/specs"
76: export PATH=/bin:.:$PATH
78: Write this into a script and source it in at each bash invocation, or
79: put it into your .bashrc.
81: If you don't bother and want to make it yourself, type
85: configure has the following useful parameters:
86: --enable-force-reg Use explicit register declarations if they appear in
87: the machine.h file. This can cause a good speedup,
88: but also incorrect code with some gcc versions on
89: some processors (default disabled).
90: --enable-direct-threaded Force direct threading. This may not work on
91: some machines and may cause slowdown on others.
92: (default disabled)
93: --enable-indirect-threaded Force indirect threading. This can cause a
94: slowdown on some machines.
95: (default enabled)
97: After covering all inconveniences, type
101: Now you can check whether your shiny new Forth system works. Say
103: make test
105: You can run some benchmarks with
107: make bench
109: and compare them with the results in Benchres and in the manual. DOS
110: and OS/2 don't allow to run the benchmarks, since the command TIME
111: means something different there.
113: Don't try to do "make install" there, it won't work, either. It is not
114: possible to "make dist" or "make bindist", too, because of the
115: limitations of DOS command lines.
117: Add the following entry to your Autoexec.bat:
119: SET GFORTHPATH=<your gforth source directory>;.
121: Use / instead of \ in your gforth source directory. Gforth now uses
122: ';' as path separator for DOS and OS/2 (not for Cygwin32), so you
123: won't have problems with DOS pathes that may contain ':', which is the
124: default path separator in Unix. Use ~+ for the current directory.
126: For paper documentation, print gforth.ps (a Postscript file (300dpi
127: fonts, i.e., it works, but does not produce best quality on better
128: printers)), or say
130: make gforth.dvi
132: and print the resulting file gforth.dvi (you need TeX for that! But
133: with TeX you can print it even if you don't have a Postscript printer
134: nor Ghostscript). You could be able to make a HTML version of the
135: document, but AFAIK there is no texi2html for DOS available, as there
136: is no perl available. You should get the HTML pages from the same
137: location where you got Gforth or from
