Subject:  68)! Where can I get an X server on a PC (DOS or Unix)?

	MIT X11R5 already provides a server to many 386/486 *Unixes* with 
support for many of the popular video graphics adapters; and for other 
non-MSDOS PCs you can obtain a server from these sources:

	XFree86 (formerly X386 1.2E) is an enhanced version of X386 1.2, which 
was distributed with X11R5; it includes many bug fixes, speed improvements, and
other enhancements. Source for version 1.1 [10/92] is on export.lcs.mit.edu in 
pub/contrib, ftp.physics.su.oz.au in /X386, and ftp.win.tue.nl in /pub/X386. In
addition, binaries are on ftp.physics.su.oz.au, and ftp.win.tue.nl among other 
systems. Info: x386@physics.su.oz.au.
	Note: this package obsoletes Glenn Lai's Speedup patches for an 
enhanced X11R5 server for 386 UNIXes with ET4000 boards (SpeedUp.tar.Z on 
export).


	Metro Link Inc. (305-970-7353, sales@metrolink.com; in Europe contact
ADNT, (33 1) 3956 5333) ships an implementation of X11R4 for the 386/486 Unix
market.

	SGCS offers X386 Version 1.3, based on Thomas Roell's X11R5 two-headed
server, in binary and source form. Information: 408-255-9665, info@sgcs.com.

	ISC, SCO, UHC, and other well-known operating-system vendors typically
offer X servers.

	For MSDOS PCs:

Daniel J. McCoy (mccoy@gothamcity.jsc.nasa.gov) has started posting monthly a 
list of non-UNIX servers for PCs, Macs, and Amigas; it includes pricing 
information. The current copy is kept on export in contrib as 
XServers-NonUNIX.txt.Z. 

An article on PC X servers appears in the March 2, 1992 Open Systems Today.

	Also of possible use:

	Net-I from Programit (212-809-1707) enables communication among 
DOS, OS/2 and Unix machines and can be used to display PC sessions on your
Unix X display.


----------------------------------------------------------------------
Subject:  69)  Where can I get an X server on a Macintosh running MacOS?

	eXodus from White Pine Software (603-886-9050) runs on any Mac with
at least 1MB of memory and runs the X server within a standard Macintosh 
window.  Version 3.0 [6/91] supports intermixing of X and Mac windows and
the ADSP protocol. The version supports the SHAPE extension and includes
DECwindows support.

	Apple's MacX runs on MacPlus or newer machines with >= 2MB of memory
and system software 6.0.4 or later. Version 1.1 is fully X11R4-based.  It 
supports full ICCCM-compatible cut and paste of text AND graphics between the 
Macintosh and X11 worlds, the SHAPE extension (including SHAPEd windows on the 
Macintosh desktop), an optional built-in ICCCM-compliant window manager, X11R4 
fonts and colors, a built-in BDF font compiler, and built-in standard 
colormaps. Upgrades to MacX are available by ftp from aux.support.apple.com. 
Info: 408-996-1010.  
	[Note: MacX is also the name of a vax-mac xmodem transfer utility.]

	Also: 

	Liken (1-800-245-UNIX or info@qualix.com) software enables monochrome
68000 Mac applications to run on a SPARC system running X. 
	Xport (1-800-245-UNIX (415-572-0200) or xport@qualix.com) enables Mac 
applications to display on an X-based workstation by turning the Mac into an X 
client.
	Intercon has a product called Planet-X which enables Mac applications
to display on an X server.

----------------------------------------------------------------------
Subject:  70)  Where can I get X for the Amiga?

	The new Amiga 3000 machines offer an X server and OPEN LOOK tools and
libraries on a full SVR4 implementation.

        GfxBase, Inc. provides "X11 R4.1" for the AmigaDos computer; it 
contains X11R4 clients, fonts, etc., and a Release 4 color server. An optional

	Xgraph's Xtool (408-492-9031) is an X server implemented in SunView 
which boasts impressive results on Sun 3 and SPARC systems. [6/90]

Several companies are making hardware accellerator boards:

	Dupont Pixel Systems (302-992-6911), for Sun.

	Megatek's (619-455-5590) X-cellerator board for the Sun 3 and Sun 4 is 
based on the TI 34020; the company claims performance improvements of 5x to 
10x over the sample X11R3 server.

----------------------------------------------------------------------
Subject:  72)  Where can I get a server for my high-end Sun graphics board?

        Takahashi Naoto (Electrotechnical Laboratory, ntakahas@etl.go.jp) has 
modified the MIT X11R5 server to support the Sun CG8, CG9, and CG12 boards.  
The files are on export in contrib/Xsun24-3.[01].tar.Z.  Note that both files 
are necessary to build Xsun24-3.1.

	The JPL R5 Xsun Multi-screen server is a general purpose replacement
for the MIT server/ddx/sun layer; it provides for the screen to be split among
several monitors and implements several other features above the MIT 
implementation. Available on export.lcs.mit.edu in the file
contrib/R5.Xsun.multi-screen.tar.Z. [Kaleb Keithley, kaleb@thyme.jpl.nasa.gov,
12/91; the file was updated 28 Sep 92.]

----------------------------------------------------------------------
Subject:  73)  Where can I get an "X terminal" server for my low-end Sun 3/50?

	Seth Robertson (seth@ctr.columbia.edu) has written Xkernel; the current
version [1.4 as of 8/91, 2.0 expected RSN] is on sol.ctr.columbia.edu 
[128.59.64.40] in /pub/Xkernel.gamma. It turns a Sun 3/50 into a pseudo- X 
terminal; most of the overhead of the operating system is side-stepped, so it 
is fairly fast and needs little disk space.
	A similar approach is to run the regular X server by making /etc/init
a shell script which does the minimal setup and then invokes Xsun, like this
example script from mouse@larry.mcrcim.mcgill.EDU:

#! /bin/sh
exec >/dev/console 2>&1
/etc/fsck -p /dev/nd0
case $? in
 	0)	;;
 	4)	/etc/reboot -q -n
 		;;
 	8)	echo ND fsck failed - get help
 		/etc/halt
 		;;
 	12)	echo Interrupted
 		/etc/reboot
 		;;
 	*)	echo Unknown error in reboot fsck - get help
 		/etc/halt
 		;;
esac
/bin/dd if=/tmp-fs of=/dev/nd2 bs=512 count=128 >/dev/null 2>&1
/etc/mount /dev/nd2 /tmp
/etc/ifconfig le0 netmask 255.255.255.0 broadcast 132.206.41.255
/etc/mount -o ro apollo:/u2/x11/lib /local/lib/X11
/etc/route add default 132.206.41.1 1 >/dev/null
set `/etc/ifconfig le0`
exec /Xsun -once -multidisp -mux -query `(sh -vn </local/lib/X11/xdm-servers/$2 2>&1)`

	In addition, the xman client can be used to preview troff documents
which use the -man macros (i.e. man pages).
	If psroff is used its output can be viewed with a PostScript previewer.

In addition:

	xproof, an X previewer for ditroff has been contributed by Marvin 
Solomon (solomon@cs.wisc.edu); version 3.5 is available on export in

Subject:  86)  Where can I get a WYSIWYG interface builder?

	A new release of the DIRT interface builder by Richard Hesketh works 
with X11R5 and includes some support for the Motif widget set. From the README:
  This builder allows the interactive creation and rapid prototyping of X user
  interfaces using the X Toolkit and a number of Widget Sets.  Dirt generates
  "Wc - Widget Creation" resource files and this distribution also includes the
  Widget Creation Library (version 1.06, with the exception of the demos and
  Mri/Ari source code) with the kind permission of its author David E. Smyth.
Check dirt.README, dirt.A2.0.tar.Z, and dirt.PS.Z on export.lcs.mit.edu:contrib.

	The InterViews 3.0.1 C++ toolkit contains a WYSIWIG interface builder 
called ibuild. ibuild generates code for an InterViews application complete 
with Imakefile and an X-resource file. Documentation is /pub/papers/ibuild.ps 
on interviews.stanford.edu (36.22.0.175).
	Quest Windows's (408-496-1900) ObjectViews C++ package includes an
interactive building tool. 

	Druid (Demonstrational Rapid User Interface Development) runs on SPARC 
machines using OSF/Motif 1.0; it is intended eventually to be a full UIMS but 
apparently now has only support for creating the presentation components, for 
which it generates C/UIL code. Info: Singh G, Kok CH, Ngan TY, "Druid: A System
for Demonstrational Rapid User Interface Development". Proc. ACM SIGGRAPH Symp 
on User Interface Software and Technology (UIST'90). ACM, NY, 1990, pp:167-177.

	The BYO interface builder is implemented in tcl.

Also:
	In addition, these commercial products (unsorted) are available in 
final or prerelease form [the * following the product name indicates that the 
product is known to allow the designer to specify for each widget whether a 
particular resource is hard-coded or written to an application defaults file,
for at least one form of output]. Some are much more than user-interface tools;
some are full user interface management systems:

	In addition, Neuron Data (1 415 321-4488) makes Open Interface, a 
window-system-independent object toolkit which supports interfaces which are 
or resemble (supersets of) Mac, Windows, and Motif and Open Look; the package 
includes an interface builder.

       In addition, the GRAMMI builder supports the development of Ada/X 
applications using its own set of objects which are planned to have a Motif 
look.  GRAMMI is written in Ada and generates Ada specs and stub bodies. 
(1-800-GRAMMI-1).

	In addition, these non-WYSIWYG but related products may help for goals 
of rapid prototyping of the application interface:

	WCL: the Widget Creation Library. Basically describes the widget
hierarchy and actions in a resources file; available from fine archive servers
everywhere, including devvax.jpl.nasa.gov (128.149.1.143) in pub/. Wcl provides
a very thin layer over Xt without any internal tweaking. 2.03 became available
11/92.
	WINTERP: an Xlisp-based Motif toolkit allows for interpretive 
programming. The copy on the R4 tape is outdated; get a copy off export or 
email to winterp-source%hplnpm@hplabs.hp.com. 
	The Serpent UIMS permits the building of user-interfaces without 
specific knowledge of coding but with an understanding of attributes being set
on a particular [Motif] widget.  Beta Release 1.2 is available from 
ftp.sei.cmu.edu (128.237.1.13) and can be found in /pub/serpent.  Serpent is 
also available on export.lcs.mit.edu (18.24.0.11) in /contrib/serpent. Email
questions can go to serpent@sei.cmu.edu. A commercial version of Serpent is
available as "Agora" from ASET, 221 Woodhaven Drive, Pittsburgh, PA 15228.
	Garnet is a Common Lisp-based GUI toolkit. Information is available 
from garnet@cs.cmu.edu.
	MetaCard is a hypertext/Rapid Application Development environment
similar to Apple/Claris Corporation's HyperCard (info@metacard.com). MetaCard 
is available via anonymous FTP from ftp.metacard.com, csn.org, or 
128.138.213.21.

----------------------------------------------------------------------
Subject:  87)  Where can I find X tools callable from shell scripts?
I want to have a shell script pop up menus and yes/no dialog boxes if the user 
is running X.

	Several tools in the R3 contrib/ area were developed to satisfy these
needs: yorn pops up a yes/no box, xmessage displays a string, etc. There are
several versions of these tools; few, if any, have made it to the R4 contrib/ 
area, though they may still be available on various archive sites.
	In addition, Richard Hesketh (rlh2@ukc.ac.uk) has posted the xmenu
package to comp.sources.x ("v08i008: xmenu") for 1-of-n choices.  [7/90]
	Two versions of XPrompt have been posted to comp.sources.x, the latter
being an unauthorized rewrite. [R. Forsman (thoth@reef.cis.ufl.edu), 1/91]
	There is a version of XMenu available from comp.sources.x; it is
being worked on and will likely be re-released.
	xp-1.1.tar.Z, xpick-1.0.tar.Z and xzap-1.0.tar.Z on export's contrib/
are tools by Gerry.Tomlinson@newcastle.ac.UK which act as X versions of the 
simple display and choice-making tools in K&P. [4/92]

----------------------------------------------------------------------
Subject:  88)! Where can I get an X-based debugger?

	xdbx, an X interface to the dbx debugger, is available via ftp from 
export. The current [1/91] version is 2.1 patchlevel 2.
	An X interface to gdb called xxgdb is more like xdbx 2.1.2. It is part 
of comp.sources.x volume 11 [2/91]. 
	mxgdb is a Motif interface to gdb by Jim Tsillas 
(jtsillas@bubba.ma30.bull.com); version 1.1.3 was posted to alt.sources 2/92.
Previous versions are on export.
	UPS is a source-level debugger which runs under the X11 and SunView
window systems on Sun and DEC platforms. It is available from export 
(18.24.0.11) as contrib/ups-2.45.tar.Z and unix.hensa.ac.uk (129.12.21.7) in
/pub/misc/unix/ups (or try mail to archive@unix.hensa.ac.uk). [10/92]

Also:
	MIPS produces a highly-customizable (WCL-based) Visual Debugger.
	You should be able to use Sun's dbxtool with its X11/NeWS server.
	The CodeCenter (617-498-3000) source-level debugger, available on most
major platforms, includes an X-based interface.
	AT&T offers the eXamine Graphical Interface, an X11 interface to dbx
and C++ dbx for Sun3 and Sun4 and sdb and sdb++ for 386 and 3B2 platforms. Call
1-508-960-1997 or contact examine@mvuxi.att.com for more information.
        Solbourne (+1 303-678-4626) offers PDB, its X-based debugger for C, C++
and Fortran.  PDB uses the OI toolkit and runs in either Open Look or Motif 
mode. 
	SCO (info@sco.com) offers dbXtra as part of several development 
systems.

----------------------------------------------------------------------
Subject:  89)  How can I "tee" an X program identically to several displays?

	There are several protocol multiplexer tools which provide for the 
simultaneous display of X clients on any number of machines.
	XMX (an X Protocol Multiplexor) is available from wilma.cs.brown.edu 
(128.148.31.66) as pub/xmx.tar.Z It works independently of the server and does
not affect the application being shared; it was developed for use in the
electronic classroom.
	XTV is a conference program which can be used to duplicate the
"chalkboard" on several displays. Release 1 is available on the X11R5 contrib
tapes; a more recent version is on ftp.cs.odu.edu as pub/wahab/XTV.r2.tar.Z.
	SHX from Michael Altenhofen of Digital Equipment GmbH CEC Karlsruhe 
also does this; it is a "WYSIWIS" (What You See Is What I See) package in the 
context of a computer-based learning/training tool to provide online help from
remote tutors but is also useful for general window sharing. Information: 
shX@nestvx.enet.dec.com.  SHX can be found on export and 
		gatekeeper.dec.com:/pub/X11/contrib/shX.tar.Z, 
		crl.dec.com:/pub/X11/contrib/shX.tar.Z 
Modifications to SHX for color mapping and private color allocation by
Mark J. Handley (M.Handley@cs.ucl.ac.uk) are on cs.ucl.ac.uk in 
car/shX.car.tar.Z.
	XTrap is implemented as a server/library extension and can be used
to record and then replay an x session. It is available as:
		gatekeeper.dec.com      pub/X11/contrib/XTrap_v31.tar.Z
		export.lcs.mit.edu      contrib/XTrap_v31.tar.Z
	wscrawl can be used as a "multi-person paint program". It's available
on sax.stanford.edu as wscrawl.shar.Z.
	Shdr implements a simple shared whiteboard, without a chalk-passing
mechanism. It's available on parcftp.xerox.com as pub/europarc/shdr.tar.Z.

Also of use:
        Hewlett-Packard Co. has a commercial product, "HP SharedX" which works
under HP-UX currently on their 300, 400, and 700 series workstations and their
HP 700/RX X Stations.  Machines receiving shared windows can be any X server.
HP SharedX consists of a server extensions and a Motif based user interface
process.  Contact your local HP sales rep. for more information.
	IBM offers a commercial product.
	Sun offers multi-user confering software called ShowMe.
	InSoft (Mechanicsburg, PA, USA) offers multi-user confering software

Subject:  90)  TOPIC: BUILDING THE X DISTRIBUTION [topic needs updating to R5]
----------------------------------------------------------------------
Subject:  91)  What's a good source of information on configuring the X build?

	This FAQ includes information on a number of "gotchas" that can bite 
you on particular system. However, the best source of general information on 
building the X11 release is found in the Release Notes. The file is bundled 
separately from the rest of the release, so if it's become separated from your 
sources you can FTP another copy separately: the file RELNOTES.[ms,PS,TXT] at 
the top of the distribution. The file RELNOTES is also available from the 
xstuff mail server.
	In addition, O'Reilly & Associates's Volume 8 on X Administration
includes information on configuring and building X.

----------------------------------------------------------------------
Subject:  92)! Why doesn't my Sun with a cg6 work with R5?

	Apparently gcc is the problem; it seems to produce fine code for all
Sun displays except for the cgsix. The new sunGX.o distributed with fix-07 
may fix the problem (note: not known to work on Solaris).

----------------------------------------------------------------------
Subject:  93)  Why doesn't my Sun with SunOS 4.1 know about _dlsym, etc.?

	If you get errors with _dlsym _dlopen _dlclose undefined, link with 
libdl.a.  Add "-ldl" to your and eventually your site.def.  You may want to 
surround it with "-Bstatic -ldl -Bdynamic" if you add it to the EXTRA_LIBRARIES 
variable, since "syslibs" get added after EXTRA_LIBRARIES on the eventual 
compilation command; otherwise you may not have a shared libdl.  (Or compile 
the stubs shared.)

[thanks to Joe Backo (joe.backo@East.Sun.COM), 12/91]

----------------------------------------------------------------------
Subject:  94)  What is this strange problem building X clients on SunOS 4.1.2?

	In SunOS 4.1.2 Sun fixed a shared-library bug in ld which conflicts
with the way X11R4 builds the shared Xmu library, causing these symbols to be
undefined when building some X11 clients: 
	_get_wmShellWidgetClass
	_get_applicationShellWidgetClass
Compiling "-Bstatic -lXmu -Bdynamic" appears to work. 

To solve the problem if you are using OpenWindows 3.0 (X11R4-based Xt), please 
contact your local Sun office and request the following patches:

Patch i.d.      Description
100512-02       4.1.x OpenWindows 3.0 libXt Jumbo patch

Subject:  95)  Why can't gcc compile X11R4 on my SPARC?
I used gcc to compile the whole distribution, but I get several segmentation
faults when running X.

	Note first that gcc on RISC machines does not necessarily result in
any performance increase; it certainly is not as noticeable as it is on the
680x0 or VAX platforms.

	Here is the problem: gcc and cc use incompatible methods of passing 
structures as arguments and returning them as function values, so when 
gcc-compiled parts of X are linked with Sun-supplied functions that pass or 
return structs, run-time errors occur.  Affected programs include rgb and 
the server.

	This is from the GCC manual:

	On the Sparc, GNU CC uses an incompatible calling convention for 
	structures.  It passes them by including their contents in the argument
	list, whereas the standard compiler passes them effectively by 
	reference.

	This really ought to be fixed, but such calling conventions are not yet
	supported in GNU CC, so it isn't straightforward to fix it.

	The convention for structure returning is also incompatible, and
	`-fpcc-struct-return' does not help.

You can duck the problem either by using cc throughout or by using it for just
the routines which cause incompatibilities; the problem cannot be solved with 
compilation flags.  

	Files which need to be compiled using cc include:
		server/os/4.2bsd/oscolor.c 
		rgb/rgb.c

	In addition, several of the "inet_" functions use structs as args or
return values:  
		clients/xhost/xhost.c 
		clients/xauth/gethost.c. 
Calls to inet_addr in /lib/CLX/socket.c and lib/X/XConnDis.c are possibly 
harmless as they don't involve structs.

Subject:  96)  What are these I/O errors running X built with gcc?
When I try to run xinit or the Xsun server I get the error 
	"Getting interface configuration: Operation not supported on socket. 
	Fatal server bug! no screens found."

	Running the gcc fixincludes script apparently didn't work. You can do 
this simple test:

	#include <sys/ioctl.h>
	SIOCGIFCONF

Run that through cc -E and gcc -E.  The last line of output is the piece of 
interest; it should be identical (modulo irrelevant differences like 
whitespace).  If the gcc version has 'x' where the cc version has 'i', your 
fixincludes run didn't work for some reason or other; go back to your gcc
sources and run `fixincludes`; then rebuild the X distribution. If they are 
identical, try running a make clean in mit/server and rebuilding, just to make 
sure everything gets compiled with the proper include files.

Subject:  97)  What are these problems compiling X11R4 on the older Sun3?
In mit/server/ddx/sun/sunCG3C.c, we have found "missing" defines for 
CG3AC_MONOLEN, CG3BC_MONOLEN, CG3AC_ENBLEN, CG3BC_ENBLEN. What should these be?

	The R4 Errata list distributed after X11R4 mentions that you can add
these lines to the file on older SunOS versions (e.g. 3.5) to compile:
        #define CG3AC_MONOLEN (128*1024)
        #define CG3AC_ENBLEN  CG3AC_MONOLEN
        #define CG3BC_MONOLEN CG3AC_MONOLEN
        #define CG3BC_ENBLEN  CG3AC_MONOLEN

	However, the Sun3 should not actually ever have the CG3 device, and so 
references to it can be removed from mit/server/ddx/sun/sunInit.c and the 
Imakefile.  [11/90]

----------------------------------------------------------------------
Subject:  98)  What are these problems compiling the X server on SunOS 4.1.1?
The file <sundev/cg6reg.h> isn't being found.

	Sun omitted <sundev/cg6reg.h> from SunOS 4.1.1. Remove the #include 
from sunCG6C.c and replace it with the line 
	#define CG6_VADDR_COLOR   0x70016000
The file has changed from earlier versions of SunOS and should not be copied 
from another distribution.

----------------------------------------------------------------------
Subject:  99)  What are these problems using R4 shared libraries on SunOS 4?
All of the executables that I try to run have the following results:
	ld.so: libXmu.so.4: not found
or even:
	ld.so: call to undefined procedure __GetHostname from 0xf776a96c

	If you are building with shared libraries on a Sun, remember that you 
need to run "ldconfig" as root after installing the shared libraries (if you've
installed X on a file-server, run it on the server's clients, too).  While 
building and installing the distribution, you need to be careful to avoid 
linking against any existing X shared libraries you might have (e.g. those 
distributed with OpenWindows).  You should make sure you do not have 
LD_LIBRARY_PATH set in your environment during the build or the installation.  
If you are going to keep xterm and xload as setuid programs, please note that 
the shared libraries must be installed in /usr/lib, /usr/local/lib, or 
/usr/5lib for these programs to work (or else those programs must be linked 
statically). [courtesy MIT X Consortium]
	Note also that the program mkfontdir is run as part of the build; it
attempts, however, to use the shared libraries before they have been installed.
You can avoid the errors by building mkfontdir statically (pass -Bstatic to
most C compilers).

Subject: 100)  Can OLIT programs run with R5 Xt? (_XtQString undefined)

This is a bug in the OLIT.  _XtQString was an external symbol that existed in 
X11R4 (upon which OW 3.0's libXt is based).  It wasn't documented and was 
removed in X11R5 (MIT's guarantee of upward compatibility between the R4 and R5
libraries only applied to the documented interface).  

A workaround is to temporarily set your LD_LIBRARY_PATH to point to the X11R5 
Xt library that you linked the program against.

Subject: 101)  How do I get around the SunOS 4.1 security hole?

	There is a security problem with certain R4 clients (xterm and xload)
running under SunOS 4.1 that have been installed setuid root and are using 
shared libraries; to avoid the problem, do one of these:
	1) make the program non-setuid. You should consult your system
administrator concerning protection of resources (e.g. ptys and /dev/kmem) used
by these programs, to make sure that you do not create additional security 
problems at your site.
	2) relink the programs statically (using -Bstatic).
	3) install the libraries before linking and link with absolute paths
to the libraries.

[from rws@expo.lcs.mit.edu (Bob Scheifler), 12/90]

The R5 version of xterm does this automatically by rebuilding xterm against the 
newly-installed libraries when xterm is being installed; this prevents an suid
program from being built with libraries specified relatively. Note that this 
may cause an inconvenience when doing the installation from NFS-mounted disks. 
Xload has been rewritten to avoid the problem.
