Annotation of gforth/INSTALL.DOS, revision 1.1
1.1 ! pazsan 1: You need DJ Delorie's port of GCC to DOS (DJGPP) to compile Gforth. DJGPP
! 2: provides a DOS extender (GO32) that allows to use the 32-bit features of
! 3: the 80386, but on the other hand it requires at least an 386.
! 4:
! 5: Gforth hasn't been tested with EMX, using EMX will require some changes in
! 6: the console IO part. If you don't want to install this package (quite
! 7: large), look for a binary distribution of Gforth for DOS. You must have a
! 8: version of GNU make, because DOS make programs are likely to have problems
! 9: with the Makefile. If you want to change Gforth, you may need GNU m4, too.
! 10:
! 11: If you don't bother and want to make it yourself, type
! 12:
! 13: configure
! 14:
! 15: There are no options for configure, because DOS can't execute a real
! 16: configure script, all the configuring stuff is done on a real operating
! 17: system. If you want to change something (e.g. use FORCE_REG or
! 18: DIRECT_THREADED), you have to change the makefile yourself. Be careful! DOS
! 19: command line arguments are limited to an overall size of 126 bytes, so
! 20: adding a new define in the makefile will make it too long. In this case add
! 21: the define at the beginning of machine.h instead, or create a file
! 22: containing all extra options, and add @<filename> to the defines (move the
! 23: -DDEFAULTPATH-define into this file, and it will fit into the command line).
! 24:
! 25: After covering all inconveniences, type
! 26:
! 27: make gforth
! 28:
! 29: and after this finishes, type
! 30:
! 31: make
! 32:
! 33: We apologize for the inconveniences, we did not invent the 640k limit
! 34: that prevents doing make straight forward. You may run out of memory
! 35: anyway, because GCC eats up lots of it while compiling engine.c. Keep
! 36: enough space free on your harddisk to allow GCC to swap.
! 37:
! 38: If you want to add some defines like -DFORCE_REG, type
! 39:
! 40: make gforth XDEFINES=-DFORCE_REG
! 41:
! 42: instead.
! 43:
! 44: Now you can check whether your shiny new Forth system works. Say
! 45:
! 46: make test
! 47:
! 48: You can run some benchmarks with
! 49:
! 50: make bench
! 51:
! 52: and compare them with the results in Benchres and in the manual.
! 53:
! 54: Don't try to do "make install", it won't work, either. It is not possible to
! 55: "make dist" or "make bindist", too, because of the limitations of DOS
! 56: command lines.
! 57:
! 58: Add the following entry to your Autoexec.bat:
! 59:
! 60: SET GFORTHPATH=<your gforth source directory>:.
! 61:
! 62: Use / instead of \ in your gforth source directory. Another problem
! 63: is, that Gforth uses : as path separator, and DOS pathes may look like
! 64: D:/gforth. Sorry, there is no workaround for this now.
! 65:
! 66: For paper documentation, print gforth.ps (a Postscript file (300dpi
! 67: fonts, i.e., it works, but does not produce best quality on better
! 68: printers)), or say
! 69:
! 70: make gforth.dvi
! 71:
! 72: and print the resulting file gforth.dvi (you need TeX for that! But
! 73: with TeX you can print it even if you don't have a Postscript printer
! 74: nor Ghostscript). You could be able to make a html version of the
! 75: document, but AFAIK there is no texi2html for DOS available, as there
! 76: is no perl available.
