How to unset XKEYSYMDB?

Hello, all

I am trying to use a new PDK.

This PDK requests:
1) set some environments such as OPUSDIR = <Cadence_install_path>
2) link Cadence_install_path>/tools/dfII/local
-> <design_kit_install>/xxxxxxx/local
But the change will bother other CDS users who're using other PDK. So a
Cadence install with all files linking to the Cadence install is
created, except for the "local" which is linked to
<design_kit_install>/xxxxxx/local

The reason for the link is that the PDK provides some utility and menus
there.

Then I execute the PDK script which set some envs and then invoke
Cadence from OPUSDIR (OPUSDIR is set to the path of created Cadence
mentioned above in 2).

The problem I met is like I can't use keyboard to type in many menus
and windows. Most of the warning message is like:
--------------------------------------------------------------
\o Warning: translation table syntax error: Unknown keysym name:
osfActivate
\o Warning: ... found while parsing ':<Key>osfActivate:
ManagerParentActivate()'
.......
\o Warning: Cannot convert string "<Key>SunCopy" to type VirtualBinding

.......
--------------------------------------------------------------

I googled and found a few similar questions asked before. It is said to
have something to do with "unset XKEYSYMDB".
I just wonder when I need unset the env? before running the
script/Cadence or what? And once the env is unset, the Cadence I guess
can't find right keyboard mapping. So what will Cadence do after that?
Thanks for reading through this little long story. Any comments will be
appreciated much.

Hi Andy,

The question is, where is XKEYSYMDB being set? Is it in a system file (eg.
/etc/bashrc), or in your own dotfiles (eg. ~/.bashrc, ~/.cshrc, etc)? I've
seen a few people who've had this problem, and in all cases they were setting
it up themselves, it was NOT set by the system. The value of XKEYSYMDB was, in
case you were wondering, completely platform-specific and entirely
inappropriate for non-Solaris platforms, which was when they noticed the problem.

If you are setting it yourself in your own dotfiles, the simple solution is to
remove that line and logout/log back in. If you don't want to go to the extent
of logging out and in again, then you could put a line in your shell startup
file (~/.cshrc for csh, ~/.bashrc for bash, etc) which explicitly unsets the
variable (since it will be set in your login environment, all new shells will
inherit this unless you either logout or explicitly unset it).

Don't worry about the tools not being able to find the keymap - this is really
nothing we're doing explicitly with the tools, it's a low-level X thing. Once
you unset XKEYSYMDB, you shouldn't have any more problems, but if you do, one
other cause of being unable to use the mouse or keyboard are the locale
environment variables - from 'man locale':

LANG=locale_x
LC_CTYPE="locale_x"
LC_NUMERIC="locale_x"
LC_TIME="locale_x"
LC_COLLATE=locale_y
LC_MONETARY="locale_x"
LC_MESSAGES="locale_x"
LC_ALL=

You probably won't have too many (or any) of these set, but I've seen problems
if they're set to "C". If you still experience problems after unsetting your
XKEYSYMDB envar, try playing about with your locale settings. LANG=C usually
causes problems, for some reason - if you have this set, try unsetting it and
see if that helps.

Let me know if this doesn't work...

Regards,
Graeme.

 

You pretty much should never have XKEYSYMDB set. When it is not set, the
XKeysymDB file is found in the default location -- in /usr/openwin/lib/X11 on
a Solaris system.

In most cases you WANT to use the default XKeysymDB file because it is the
correct one for the system.

The only time XKEYSYMDB should be set is when you have a specific reason.
Such as a long time ago before Solaris when the SunOS XKeysymDB file didn't
have keys required for NetScape, so you needed to point to NetScape's
XKeysymDB file when running NetScape.

But this is no longer necessary for NetScape, since Solaris has a proper
XKeysymDB.

Hi, Graeme, Pete and all

Thanks so much for reading my post and reply. I tried what you guys
said but I was still out of luck. I should have specified the problem
in more detail. Actually, as far as I try the only weird thing only
happens to the libManager Window. When you opened a schematic or analog
artist window, the keyboard and mouse work well. But the libManager was
dumb to the input from keyboard but responsed to mouse well. I guess
that it has nothing to do with the XKEYSYMDB. Any more comments?

That could be due to your locale settings.

Try "setenv LANG C" before starting the tools and see if that makes a
difference.

Hello, there

I am back with some new episodes about the problem still haunting me.
Still thousands of thanks to those read and replied my post.
After some try and communication with PDK support staff, the potential
reason to cause the problem still focuses on setting of XKEYSYMDB.
As I described above, a script is executed to invoke Cadence and
meanwhile introduce some menu and utility specific to the PDK. When I
started up Cadence and typed

getShellEnvVar("XKEYSYMDB")

in the CIW window, I got the response like

/syn/hercules/.../.../XKeysymDB

The support staff told me that if the synopsis' XKeysymDB is sourced,
the key mapping of Cadence will be messed up there.
The script is executed in Bourne shell (the first line of the script is
#! /bin/sh). And even if I inserted the lines

unset XKEYSYMDB
or
XKEYSYMDB="usr/X11R6/lib/X11/XKeysymDB"
export XKEYSYMDB

before invoking Cadence in the script, I still got the same result by
executing getShellEnvVar("XKEYSYMDB").
I guess that the var XKEYSYMDB is overrided somewhere I dont know. My
login shell is tcsh and I didn't find some conflict from the system
profile file.
I dont know much about Unix on the system level, so I am still looking
forward to any comments here. Thanks!

I also attach the script below. I had to modify the script a little for
some reason.


#! /bin/sh
# This script is enhanced to be worked for both Solaris & Linux
# It will launch data from /designPackages which can do:
#
#
# Read "I" for environment setup for 12 different binaries that
# integrate into this PDK.
# Read "II" to setup your EDA binaries.
# Read "III" for the upcoming change log.
#-----------------------------------------------------------------------------
#
#-----------------------------------------------------------------------------

# I. Make sure the following environment variables and
# defined/installed at your site.
# ----------------MUST
INSTALL/setup----------------------------------------
# DPPDK - DesignPackages installation path
# default is: /designPackages
# OPUSDIR - Cadence 50 installation path
# default is: /cad/cadence.IC50
# -----------------Optional install/setup if the following tool will
be used
# avanti_home_dir - Advanti Hercules tool installation path
# default is: /cad/avanti/hercules
# HSPICEDIR - Spice installation path
# default is: /cad/hspice
# LDV - 50 Verilog path

Hi Andy,


This is strange... so in the script you posted, you have unset XKEYSYMDB before
calling the exe and it's still set?:

If you start a new shell, is XKEYSYMDB set by default? If it is, you probably
need to figure out where this is being set. If you are on Linux (I couldn't
see any mention of the OS you're using, but this issue usually crops up on
Linux), then try doing 'Ctrl-Alt-F1' to go to a virtual terminal and login.
See if XKEYSYMDB is set after you login. If so, you probably need to trace
what you are sourcing in your ~/.tcshrc (assuming tcsh is your default shell
and you're not starting it manually after the default shell is invoked).
(Press 'Ctrl-Alt-F7' to get back to your X session!). Do any other users have
XKEYXYMDB set when they login, or is it set when they start a Cadence product?

The manpage for tcsh indicates a number of files which you may want to look into:

------------------------
FILES
/etc/csh.cshrc Read first by every shell. ConvexOS, Stellix and Intel
use /etc/cshrc and NeXTs use /etc/cshrc.std. A/UX,
AMIX, Cray and IRIX have no equivalent in csh(1), but
read this file in tcsh anyway. Solaris 2.x does not
have it either, but tcsh reads /etc/.cshrc. (+)
/etc/csh.login Read by login shells after /etc/csh.cshrc. ConvexOS,
Stellix and Intel use /etc/login, NeXTs use
/etc/login.std, Solaris 2.x uses /etc/.login and A/UX,
AMIX, Cray and IRIX use /etc/cshrc.
~/.tcshrc (+) Read by every shell after /etc/csh.cshrc or its equiva-
lent.
~/.cshrc Read by every shell, if ~/.tcshrc doesn't exist, after
/etc/csh.cshrc or its equivalent. This manual uses
`~/.tcshrc' to mean `~/.tcshrc or, if ~/.tcshrc is not
found, ~/.cshrc'.
~/.history Read by login shells after ~/.tcshrc if savehist is
set, but see also histfile.
~/.login Read by login shells after ~/.tcshrc or ~/.history.
The shell may be compiled to read ~/.login before
instead of after ~/.tcshrc and ~/.history; see the ver-
sion shell variable.
~/.cshdirs (+) Read by login shells after ~/.login if savedirs is set,
but see also dirsfile.
/etc/csh.logout Read by login shells at logout. ConvexOS, Stellix and
Intel use /etc/logout and NeXTs use /etc/logout.std.
A/UX, AMIX, Cray and IRIX have no equivalent in csh(1),
but read this file in tcsh anyway. Solaris 2.x does
not have it either, but tcsh reads /etc/.logout. (+)
~/.logout Read by login shells at logout after /etc/csh.logout or
its equivalent.
------------------------

Have you asked the support staff if they know where it's being set? Are you
sourcing any Synopsis setup scripts anywhere in your tcsh config files?

Failing that, you may want to just try a grep

Something like this may do it:

grep XKEYSYMDB .[a-zA-Z0-9]*
grep XKEYSYMDB /etc/*

Of course, if you're sourcing something which sets this, the greps above won't
find it - you'll have to manually inspect each file your shell initialization
sources to see if it is setting XKEYSYMDB (or loading another file which does).

Regards,
Graeme.

 

That's probably because it should be "unsetenv XKEYSYMDB" not
"unset XKEYSYMDB". unset is the csh command to unset a shell variable.
unsetenv is the csh command to unset an environment variable.

Andrew.

 

Just to illustrate this:

andrewb_15> setenv FRED hello
andrewb_16> unset FRED
andrewb_17> echo $FRED
hello
andrewb_18> unsetenv FRED
andrewb_19> echo $FRED
FRED: Undefined variable

 

Andrew, the script looks like beeing written in sh (use of export,
syntax of if, ...) , and for sh unset remove the environment variable.

Yours,

 

Jean-Marc,

You're quite right. I don't think I've had enough coffee this morning
(actually I've not had _any_ coffee) and so I missed the fact that it was
a Bourne shell script.

Silly me.

Andrew.

 

Andrew, Bunyan

I tried according to what you said. But still out of luck there.
As I told you before, I found that the var XKEYSYMDB was set to the
path below

"/syn/hercules/lib/X11/XKeysymDB"

which might mess up the Cadence key mapping.

However I found that actually there's no such a directory "/lib" under
"/syn/hercules" in our Unix system, which might be a one expected by
the PDK. Since the PDK requests that environment var "avanti_home_dir"
be set to the path of installation directory of avanti Hercules (which
is /syn/hercules in our case). I took a try to change it to a fake path
like "/syn1/hercules". This did make a fool of Cadence/PDK. Right now
we are free of the typing problem in the Cadence libManager and all
warnings from that. When I check the setting of XKEYSYMDB in CIW
window, Cadence returns me

XKEYSYMDB="/usr/X11R6/lib/X11/XKeysymDB", which should be a correct
response.

But still a little problem there, when I open "create->new library",
the menu appears without "attach to a library" option. So I will talk
to our administrator to do further test on that.
Thanks a lot!

-Andy

 

Dude, that's my *last* name!

If I understand this correctly, setting "avanti_home_dir" to a non-existent
path causes the XKEYSYMDB to remain at the /usr/X11R6/... value above? Does
your setup (eg. .cshrc or any other files you source) use avanti_home_dir
anywhere, in particular, does it source any files from that directory? I'm
guessing that, somewhere in /syn/hercules is the file which is setting
XKEYSYMDB - try a recursive grep and see what you come up with.

Regards,
Graeme.

 

It looks like his script is actually a Bourne shell script, in which
case unset is correct.

(It's generally preferred to write shell scripts in Bourne; I've
encountered some radically broken implementations of csh on fairly
common platforms...)

 

Also, Bourne sh tends to be have less overhead than csh.

Oh, Graeme

I'm terribly sorry for that. I should have used "Mr. Bunyan" in my last
post.

As you predicted, I did find that there exist the shell files
"hercules_setup.csh" and "hercules_setup.sh" under the directory
"/syn/hercules". Also there's setup about the environment var of
"XKEYSYMDB" in these files. But I am still confused here.

I pick up all of setup involved with "avanti_home_dir" from the script
and paste them as below.

if [ ! "$avanti_home_dir" ]; then
avanti_home_dir="/cad/avanti/hercules"
export avanti_home_dir
fi

if [ -d "${avanti_home_dir}/bin" ]; then
PATH="$avanti_home_dir/bin:$PATH"
export PATH
fi

if [ ! "$HERCULES_HOME_DIR" ]; then
HERCULES_HOME_DIR=$avanti_home_dir
export HERCULES_HOME_DIR
fi

if [ -d "${HERCULES_HOME_DIR}/bin" ]; then
PATH="$PATH:$avanti_home_dir/bin"
export PATH
fi
.......
ACEAVANTI="yes"
if [ ! -d "${avanti_home_dir}" ]; then
ACEAVANTI="no"
fi
export ACEAVANTI
.......
if [ "$avanti_home_dir" ]; then
if [ -d "${avanti_home_dir}/bin" ]; then
wkdir=`pwd`; cd $avanti_home_dir; tmpdir=`pwd`
_vv=`echo $tmpdir | grep "2003"`
if [ ! "$_vv" ]; then
echo "**ACE50 WARNING** Hercules path
(\$avanti_home_dir):$avanti_home_dir is out-of-date"
else
echo "--ACE50 INFO -- Hercules path
(\$avanti_home_dir):$avanti_home_dir OK"
fi; cd $wkdir
else
echo "**ACE50 WARNING** Hercules path
(\$avanti_home_dir):$avanti_home_dir is NOT installed"
fi fi

Actually I didn't see the script source the hercules' setup anywhere. I
guess that the script never touched the hercules' setup files at all.
In our Unix system, the file "XKeysymDB" is located under
"/syn/hercules/lib-u/X11" whereas the script actually set the var
"XKEYSYMDB" to "/syn/hercules/lib/X11" after manually setting
"avanti_home_dir" to "/syn/hercules". It means somewhere there exists
some setting like this:

XKEYSYMDB=$avanti_home_dir/lib/X11/XKeysymDB ( However we dont have the
directory "/lib" there.)

The script essentially setup some environment vars for Cadence and then
invoke icfb. I just wonder why it also do some business with Hercules
in the same script. Does it inform that Syn and Cad are co-operating
with each other?
Thanks!

-Andy

 

Have you tried "trace"ing the binary and flagging every OS file system
access.
It is tedious, but you can track down where it gets set!

Hi, G

I really like to try what you said. But I don't know much about how to
do in Unix world. Could you give me further hints on that? Thanks a
lot!

-Andy

 

Unfortunately, environment variable read/writes do not involve system
calls (the entire environment is held in userspace). strace, truss,
etc., won't see the write.
