Also some facilities might not be present, such as background images, PEX, XIE, DGA, or other X extensions.
README and README.OS2 are the most
important for the first time. Also read files that refer to your
video hardware (such as README.S3, for instance).
Please avoid cross-posting to other groups, this won't speed up answers, and usually annoys people who pay for their news and have broken software which does not recognize crossposts.
Many people who have been using the last version(s) of XFree86/OS2 will also listen in the mentioned newsgroups, and will be helpful.
Please choose a meaningful subject, preferably containing the word "XFree86" or "XFreeOS2" in the line.

CMD.EXE) the following command:startx 2>error.logxf86log.os2 file will be *sometimes* produced in the
root directory of your boot partition. In many cases,
it is not present or empty.
popuplog.os2 file resides, if it exists, in the root directory
of the boot partition. If you find one, delete it, and create the
error.log file again (see above). If there is a new one then, it
is from the current run.
Your mileage on book recommendations may vary, of course, and there is much more stuff in the shelves.
The /XFree86/lib/X11/doc/README file lists supported video hardware.
If you want to work on support for a new server actively, please send a request to
XFree86@XFree86.org. But be warned in advance: the emphasis is on active participation, and the core people there carefully check if this is really the case, and not one of the numerous requests to get access to the source code (which typically remain unanswered).README.OS2 as you were
supposed to. This driver is in /XFree86/lib/xf86sup.sys and needs
to be added as a DEVICE in CONFIG.SYS. XFree86/OS2 won't work without
it.
FASTIO.SYS driver. The XF86SUP.SYS driver is
a superset of this. Remove FASTIO.SYS from your CONFIG.SYS; you won't
need it anymore, XF86SUP.SYS will take over all the functions.
README.OS2 says
you must get and install EMXRT.ZIP. A suitable EMXRT.ZIP should be
in the directory where the 312F*.zip files are.
EMX.DLL still left
in your LIBPATH. We make it even easy for you as we tell you where it
is: in X:\foo\bar\emx.dll. Remove this file (read the EMX instructions on
how to do this). If you still get this
error message, now with a different directory, you should seriously
consider to clean up your disk to get rid of the various instances of
outdated code.
CONFIG.SYS? If so, analyze the error
messages that checkinstall tells you. Usually it is right with its
comments!
XFWARN... denotes a warning. It is not fatal
but you should be aware that this can point out a problem.
Fixpack 5 contains some recommended fixes. You might consider to install at least this one.
In the future, you might be forced to install Fixpack 17 or later (or get Merlin), because this has certain support which becomes mandatory in the future.
And yes: fixpacks are cumulative, i.e. a FP with a higher number contains all fixes of the ones with a lower number.
XF86SUP.SYS driver of 3.2
has a specific addition which is only available with kernels of FP17
and newer. In normal XFree86/OS2, you don't need this feature
yet. Ignore this message. On the other hand, you might consider
installing a new fixpack some day.
PKUNZIP? Or did you use the zip function
of Object Desktop (which doesn't work either)?
Or did you unpack onto a FAT partition?
And did you read what the docs say about this?
EMX.DLL in your system, or that
XF86SUP.SYS and OS/2 got severely confused. I have seen this twice
since EMX.DLL was up-to-date; in both cases some other effects brought
me to the conclusion that a reboot would be the best solution.
startx.
This will display a number of messages for a short time. If something
goes wrong, you will likely see it there. To get a permanent
version of these messages, simply redirect them into a file 'error.log'
by starting the system in the following way:startx 2>error.logREADME.OS2 file. It is located at
\XFree86\lib\X11\XConfig. This file is named XF86Config on Unix
systems, and may be located in various other places there. It MUST be
in the specified place in XFree86/OS2, in contrast to Unix, though.
This file is a text file, and in some cases you MUST edit things
there (see below elsehere).
CONFIG.SYS which works with OS/2").
No. There is no free lunch. The cards database lists a few hundred
boards with several options each and there are many monitors as well,
so there are countless combinations of XConfig files. You must go
through the xf86config configuration program for yourself - everyone
else had to do this as well; so don't ask for this.
xmodmap).
In XFree86/OS2-3.2, this works now.
None of the above and you
will be offered a menu that gives you standard national support. If this
is not sufficient, \XFree86\lib\X11\xkb\* offers the source files
to create a totally private setup. Check the official X11 documentation.
You can still use xmodmap as well.
XConfig
file. For many videocards, the file contains option lines in the
Device section which are commented out (with a # symbol) by
default. These options are named no_linear, nomemaccess ,
noaccel, or even totally different. Video cards are often different
even when coming from the same manufacturer and having the same brand
name, but they aren't (some manufacturers are notorious for changing
the horses at full speed while the race is going on). You should try
out options that are listed in this section and use the one which
works for you. Also consult the README.yourservername (e.g. README.S3)
if it exists for specific hints.
CTRL-ALT-BACKSPACE keys.
CTRL-ALT-KEYPAD+ and CTRL-ALT-KEYPAD-. This does
not neccessarily mean that there ARE other resolutions. With 1MB of
video RAM, you cannot have more than 1024x768x8, for instance you
have not enough video RAM for 1280x1024x8. The X server calculates
the allowed resolutions from the available Clocks, the video RAM,
the monitor limits, and the available mode lines. This means, if you
have a standard-VGA 14" monitor for 640x480 @ 70Hz, the xserver wcould
refuse to offer you 1024x768, because it would result in sync
frequencies beyond the limits of the monitor. The X server is
conservative here, so it might be still possible to tune the
frequencies to the limits of the monitor manually (see Q 2.23).
Modeline statements in the XConfig
file. By default, the XConfig file has the standard VESA resolutions.
For a non-standard resolution, you must calculate the 8 numbers in the
modeline manually. Get the file
ftp://borneo.gmd.de/pub/misc/XFree86OS2/fixes/videomod.zip for a documentation
for this.
xvidtune which allows
to shift and stretch the X screen. This will produce a new mode line
which you manually have to add to the XConfig file in the place of the old
misaligned one. BTW: This program usually won't work with a LCD
display (see also Q 2.22).
Clocks and
VideoRam lines correctly, and correct them if necessary.
X -probeonly, please read what the program tells you. Some other
cards, for instance SVGA cards have fixed frequencies, you must run
this. Xf86config has been changed to call the correct X server, but
this might not work in all cases. In this case, run it from a CMD
window manually by:\XFree86\bin\XF86_yourserver.exe -probeonly | grep "Clocks"XConfig file.
Note: this line shows that you need the grep program (see also
Q 2.28).
xf86config calls the grep utility, which you don't
have installed. Get /os2/unix/grep20.zip from hobbes.nmsu.edu (or
elsewhere). Well, this is the last clue that X11 came from Unix; there
are a few other tools you might need. /os2/unix/gnu*.zip should have
most things you'd encounter.
Screen, subsection Display of the
XConfig file, there is the line Modes
which lists all the resolutions that can be switched to with
CTRL-ALT-KEYPAD+ or CTRL-ALT-KEYPAD-. Reorder this line with a text editor.
Attention: there are many of these sections, for SVGA, Mono, Accel,
AND for your video card AND for different numbers of colors.
-bpp 16 or -bpp 24. This can
be accomplished by passing this option to the startx command asstartx -- -bpp 16error.log file.
FontPath lines in the XConfig
file. You must disable (with a comment # at the beginning of the line) all
FontPath lines for font packages you haven't installed. Xf86config
will now do this by default during install, but if you add fonts
later, you need to edit XConfig manually.
BTW: it is not sufficient that just the directory is present.
Fixed is an alias, which is associated with some font in the
fonts.alias file in the directory /XFree86/lib/X11/fonts/misc. The
font is then associated with a file in the fonts.dir file in the
same place.
FontPath
line in the XConfig file.
fonts.dir file containing the
mapping between a file name and the 14-part font specifier (see
/XFree86/lib/X11/fonts/*/fonts.dir for all fonts in \PSFONTS.
Watchcat
(or any program which uses the popup mechanism in OS/2) is invoked,
the current palette is not saved. Screen corruption may also occur.
This will only affect pixel depths where a palette is used (4bpp and
8bpp).
X11ROOT:\XFree86\lib\X11, where X11ROOT is an
environment variable which contains the drive letter the directory
tree is located. The common places like /usr/X11, /usr/X11R6,
/usr/XFree86, /etc which are used for XFree86 in various Unix
flavors, are not supported to avoid the mess they have caused in
the past.
It is also there where you should put your Xconfig file, the color database (rgb.txt),
the host authorization files (X0.hosts), and various other files.
stderr gets redirected to a file
called xf86os2.log. You can find the rest of the server messages
there.
TMP must reside on HPFS. BTW: did you run "checkupdate"?
Warning: process PID=????? is accessing
/dev/fastio$, right? This is an intentional notification that some
process uses the fastio device to perform access to I/O ports. It is
also intentional that this message cannot be disabled. As long as the
PID is the process ID of the X server, everything is okay. If the PID
belongs to another, unknown process, you should seriously ask the
author of the program what he/she is doing with your hardware.
Part of the problem is that clients started in xinitrc.cmd remain under PM control (i.e. its parent is PM, not xinit, as intended), so when X goes down, it doesn't destroy these clients with it.
Currently the following methods appear to work: pop up the window list
(CTRL-ESC) and close the xinitrc.cmd process. If this does not help,
close the other remaining X processes in the same way. Alternatively
to the close function of the window list, a process kill program
(killem, killit, pmkill, etc) or Watchcat should also work.
XF86SUP.SYS from CONFIG.SYS, and if you like,
also the environment variables that were set during installation.
Attention: some of them are necessary for proper TCP/IP networking.
\XFree86.
FontPath keyword in double
quotes (").
xterm cannot connect
to the server. The real reason is probably hidden somewhere else in
the XConfig file.
xvidtune won't work with
PMX or Exceed, because it uses a specific XFree86 extension of the
X server.
\TCPIP\DLL and \TCPIP\BIN which cause name clashes and obscure crashes
of XFree86 X clients, so to run XFree86 with an installed PMX, you
must have \XFree86\bin before \TCPIP\BIN in your PATH, and
\XFree86\lib before \TCPIP\DLL. Read about BEGINLIBPATH in your
OS/2 command reference manual.
You should run the PMX server on display :0 and the
XFree86 one on display :1 (attention: the startx.cmd has this coded
to :0 by default).
xhost +remotesystemnamestartx.cmd file, or add it to the X0.hosts file). You must tell the
remote clients to use the OS/2 X server as a display by starting them
with the standard -display option, e.g.xterm -display os2systemname:0.0DISPLAY=os2systemname:0.0X0.hosts in \XFree86\lib\X11. To enable connections
from a certain host, add in a line containing inet:hostname to the
file. For example, your file may look like this:
inet:foo.edu
inet:friendly.host.edu
..X0 refers to the zero in the display name
os2systemname:0, i.e. in the case of Q 3.6 this would become a
X1.hosts then.
-query xdmcphostname for this.
xterm. A symptom may be that they won't work either if you
redirect console I/O to a COM terminal which should be possible.
bash is such an incompatible shell. See also Q 3.12 and Q 3.13.
Meanwhile, there are special ports of tcsh and ksh which
work in an xterm.
4OS2 has a number of misfeatures, politely spoken, in an xterm. We
attempt to fix this in the future. For now, don't use it in an an
xterm. If 4OS2 or another shell is in your OS2_SHELL or SHELL
variable, please add an environment variable named X11SHELL to point
to a valid CMD.EXE path, e.g.SET X11SHELL=D:\OS2\CMD.EXECONFIG.SYS. This will override the OS2_SHELL or SHELL setting
which is used otherwise.
Q 3.13. So actually
FTP does NOT work.
You may try out x3270, available from the ported software WWW page
(Q 1.15).
X11ROOT:\XFree86\lib\x11\xinit\xinitrc.cmd.
This is an editable REXX script. Usually you will only modify the
section "start some nice programs". You should use start/min to
run the command and put all arguments in '' or "", because REXX
may come to the wrong conclusion to interpret certain commands.
The last command before the exit must be started without the
start/min. If you kill this program, X11 will shutdown. Usually,
this is configured as twm. So if you select exit on the root menu
of twm, it will shutdown XFree86/OS2. Please read Q 2.46 about some
gotcha.
You might try out DXPC as an alternative, though.
term, or kermit does
not work (just before someone asks). But even with 28,8K it is no
fun without packet compression (see also Q 2.15).
You might check DXPC from the ported software page, ported
by Ron van Iwaarden. This is a public packet compression server/client
which should give some relief.
XF86Config file, and if you change the
mouse protocol entry to OSMOUSE and remove the mouse device
line. Note the config file is named XConfig in OS/2, not
XF86Config.
XF86SUP.SYS
driver which you will mainly encounter in the xterm. The following
functions are available currently:
XF86SUP.SYS installed. You need
version 1.432 or later. A usable version is always in the file
*BASE.ZIP in the XFree86 distribution, even if a XF86S*.ZIP
containing the driver source is not available. The XF86SUP.SYS version
1.420 from 3.1.2D does not have all features.
XF86SUP.SYS. Will be fixed
sometime in the future. It should not crash, at least.
Emulate3Buttons and Emulate3Timeout 50
in your XConfig file. The third button is then activated by
pressing both buttons simultaneously.
xmodmap -e "pointer = 3 2 1"
on a command line or in the xinitrc file or make an Xmodmap file
for that purpose.
.Xmodmap file.
There are sample files in /XFree86/lib/X11/xmodmap/Xmodmap.* for
various countries. If you write a new one which is not yet in the
distribution, please send it to me (Holger.Veit@gmd.de) for
inclusion into the next release.
Xmodmap files: they depend on the
X server's idea how to assign keyboard (scan) codes to keys.
Xman uses the following conventions:
MANPATH environment variable. This is a semicolon (;) separated
list of directories of the structure
drive:/dir/.../man1
Not all chapters man1-mann need to be existant.
If you have installed

Such preformatted pages are produced from unformatted pages with
tbl file.man | neqn | groff -man | gzip >file.gz
\XFree86\man\man1 this would be 1, like grep.1.

cat and gzip.
Both utilities are available from hobbes.nmsu.edu.
mkfontdir utility.
Imakefile. Simply proceed as
if you were under Unix. Run xmkmf -a to compile. Read the
programming section on special issues.
Ask whether someone is already porting it, e.g. in the newsgroup comp.os.os2.programmer.porting; if not, then do it yourself. Applications don't appear magically, unless someone really ports them. So why not YOU?
ctwm and fvwm, available through
the ported software web page (see Q 1.15).
twm by default. There is more stuff that would be worth becoming
part of the standard, such as xv, but ...well, it isn't...
So, this may be a point where companies, for instance, who are already involved in the Motif business could jump in, and offer the missing link. I have neither interest nor time to manage this.
For now, I would recommend that someone takes over the task of porting Ousterhout's TCL/TK, which at least gives a Motif look&feel and should now be pretty simple with the X11 APIs.
There is also the LessTif project to build a free Motif clone. Look at the ported software page (Q 1.15).
gcc compiler. There may
be certain restrictions and side effects involved concerning the
GPL and the use of certain libraries. I won't discuss this here,
but I would have no concerns regarding this.
If you aren't concerned either: Yes, commercial applications are allowed and welcome. THIS IS YOUR CHANCE!
312FSLIB.ZIP.
The libraries have been renamed to *_s.a to distinguish from the
DLL forwarder libraries.
gcc is free software, and most stuff written for it is also
freely available. Recompile any singlethreaded libs you want to
link to a X application.
_System. However, there may be a large number of EMXisms in them
which may prevent running. You need the EMX runtime DLLs anyway.
Imakefiles also have nice features, particularly that they
expand to Makefiles that may have several thousand lines. I have
tested numerous make programs: all but GNU make failed this benchmark
somehow. You are accustomed to XYZmake; let's say, imake is
accustomed to GNU make.
Imakefile and do not try to handcraft or patch a
Makefile. Things will go wrong!
ProgramTargetName() and LibraryTargetName()
and use them in the Imakefile, rather than hacking .exe and .lib
names. The above will work, hacking won't.
-Zmtd option, the libraries
are multithreaded by intention.
#ifdef OS2Architecture in an Imakefile to specify an
OS/2 dependent part.
#ifdef __EMX__ for
OS/2 EMX specific parts. Don't use other symbols, such as
"OS2", "__OS2__", "i386", "__GNUC__", or "__32BIT__".
Use only #ifdef, #else, #endif, not #elif, as some other compilers
don't support this.
Imakefiles silently assume they are running under Unix,
and therefore have program and library names hardcoded in.
Use the LibraryTargetName and ProgramTargetName macros to wrap
libs and programs, such as in
EXTRA_LIBRARIES = ../Xpmlib/LibraryTargetName(Xpm)
PROGRAMS = ProgramTargetName(xterm) ProgramTargetName(resize)%X11ROOT%\XFree86\... To prepend the X11ROOT part
to a file path, a special function named __XOS2RedirRoot exists
which you are supposed to use in these cases rather than an insane
own solution. The prototype of this function is:
const char* __XOS2RedirRoot(const char* pathname);
README.OS2, rather
than invent yet another variable name for USERs, HOME directories,
TMP directories, etc.
fork() is involved.
I got fork running in several situations, but it is no fun.
Try to rewrite this code where possible (well-meant advice).
\emx\lib\binmode.o. Don't change this, some code relies
on this. Rather rewrite the code to accept \r\n as a line
delimiter.
Dos* API functions, as long as they don't conflict
with EMX somehow (e.g. _beginthread vs. DosCreateThread). Stay
away from Kbd*, Mou*, Vio* calls - none of those will do what you
expect, but you can severely influence the operation of the X11
system.
#ifdef clauses.
WINDOWCOMPAT and EXETYPE OS2

scripts to REXX cmd files. Don't rely on others to install sh
or other tools just for you.
tar and gzip.
Imakefile (which is common practice with X apps),
set the X11ROOT variable to another letter than the one where you
have your X11 tree. This makes it easier for you to combine
all necessary files into a distribution.

rely on users to edit CONFIG.SYS to change the PATH or LIBPATH.
/XFree86/src/PACKAGENAME, e.g.
/XFree86/src/xfoo-0.42.
Make is a REXX cmd script which is installed in \XFree86\bin. This
script sets certain important variables and then calls the x11make.exe
program (which is gnumake 3.71) which is known to work.
You have some other make.cmd or make.exe somewhere in the path. If
you do not remove or rename this, you won't be able to compile
X11 code successfully.
Imakefile. You have not passed the correct options to gcc.
The most simple Imakefile to compile a client with just one

Note that you still need some secondary literature on special
features of Imakefile rules. A recommended book on
Imakefiles is available from O'Reilly&Assoc publ
(Using imake). Ask in your bookstore.
rcs (available from hobbes.nmsu.edu) to make copies of each
file before I modify it the first time. Later I use the modified
files to produce context diff files using rcsdiff.
When I managed to get some code working, I run make install, and
make install.man which will usually install all necessary files in
the right place. When I think the code is working correctly, I do
the following: I change the X11ROOT variable in a CMD window to
something else, e.g. from X11ROOT=d: (which it is on my system by
default) to X11ROOT=c:, and run make install install.man again.
This will build the tree of files again on C: where I can easily
pack it with the zip utility after adding README files and diff files
manually.
Thanks to all people who responded and now recognize their system mentioned here.
Another source of problems are files which contain CR-LF as a
line delimiter. We have to fix this the hard way unfortunately;
for well-defined reasons programs are linked with \emx\lib\binmode.o.
You might try to convert offending files to the Unix convention
with the program \XFree86\lib\X11\etc\fixcrlf.exe.
fixcrlf filename
This will convert the file in place. Never apply this program to
executables, fontfiles or other binaries.
We need a bug report for the program anyway.
os2.rules or os2Lib.rules)
report it as a bug. It remains your problem (you should contact and
flame the author for dirty hacks), if some Imakefile contains
Unixisms, such as sh command sequences.
commandname is CMD.EXE, it works, but if it is for instance ls
only a window is opened, but no output is generated.
