This file contains a collection of notes that various people have
provided about porting Tk to various machines and operating systems.
I don't have personal access to any of these machines, so I make
no guarantees that the notes are correct, complete, or up-to-date.
I'd be happy to receive corrections or updates.

HP-UX systems:
---------------------------------------------

1. Configuration:
	    HP-UX Release 7.05 on a series 300 (68k) machine.
	    The native cc has been used for production.
	    X11r4 libraries and include files were taken from
	    internet archives, where as the server came with HPUX release 7.05.
    
    Problems:
	    Symbol table space for cc had to be increased with: -Wc,-Ns3000
	    tkBind.c did not compile under -O:
		    C1 internal error in "GetField": Set Error Detected
		    *** Error code 1
	    tkBind.c did compile without optimization (no -O).

SCO Unix:
---------------------------------------------

Getting Tk to run under SCO Unix:

Add a "#undef select" to tkEvent.c, and remove the reference to TK_EXCEPTION
around line 460 of main.c.

Tk uses its own scheme for allocating the border colors for its 3D widgets,
which causes problems when running TK on a system with "PseudoColor"
display class, and a 16-cell colormap.

If you can't go to eight bitplanes, you can instead start the server with a
"-static" (Xsco) or "-analog" (Xsight) option, making the display class 
become "StaticColor".  This makes the entire colormap read-only, and it will
return the color that most closely maps to the desired color as possible.

Silicon Graphics systems:
---------------------------------------------

1. Append -ansiposix to the CC variable in the Makefile. The compiler,
   by default, is ANSI C with extensions, but doesn't define __STDC__ to obey
   a strict reading of the ANSI standard. -ansiposix disables the extensions
   and defines __STDC__.

2. Comment out the ranlib line in the Makefile.
