Dear Sir/Madam,Recently, I installed the newly released Fedora 7 and the latest version
of PC IRAF. Today I updated the Fedora on-line and found I was not able
to run IRAF. Each time I typed 'cl', I got 'Illegal variable name.' So
what's the problem? Thank you very much!Best regards,
Jianghua Wu

Jianghua,Try starting the session as "csh -x /usr/local/bin/cl" to trace the script as it runs, it should point to the variable name causing the problem. Please post this result if the problem isn't obvious.Cheers,
-Mike

Thank you very much, Fitz! I tried "csh -x /usr/local/bin/cl" in an xgterm terminal, the system echoed the same "Illegal variable name." and no IRAF session was started. In fact, I was able to run IRAF just after a new installation of Fedora 7. But, after I upgraded the OS on-line, the problem came out. So the problem seems relate to the update of the Fedora system. Now each time I log in as user 'iraf', the same 'Illegal variable name.' come out as the first line in each terminal.Jianghua Wu

Jianghua,Please post the output of the "csh -x" command so I can see where the script is failing ....Cheers,
-Mike

Mike, I just tried. The output is the same, 'Illegal variable name.' And then go back to the system prompt.BTW, I'm using IRAF 2.12.Best,
Jianghua

If you get no output at all from the command other than the error, try temporarily moving your .cshrc file in case the error is in that file. You might also try "csh -f -x /usr/local/bin/cl" where the '-f' will explicitly suppress the reading of the .cshrc file. An 'env' command will dump your current environment and may also provide a clue.-Mike

Mike, This is the output of the command "csh -f -x /usr/local/bin/cl":csh -f -x /usr/local/bin/cl

guiapps. lists. plot. system.
cl>Then I can run IRAF commands. So what's the problem?Cheers,

It means there's a problem in your .cshrc file (or some file that it sources). If you post the file maybe I can spot something obvious, otherwise you'll need to sort through it. Start by commenting out any line using the 'source' command to read other files, then uncomment them one-by-one until you find the problem. -Mike

BTW, as a normal user, I use bash rather than csh.I did not expect you stay so late in the night. I really in debt to you!Best,
Jianghua

Try the same trick on the .cshrc file, i.e.[code:1:bf4ef79aea]csh -f -x .cshrc[/code:1:bf4ef79aea]I suspect it'll fall over on one of the lines using e.g. the '$?' syntax which may have changed in FC7.Note you don't need to be the iraf user to start the CL, you can do it under your account and the bash just as well. BTW, it's only 19:45 here, not even close to being "late" 8-)Cheers,
-Mike

Actually, I bet it's the lines:[code:1:95ec50eff5]
alias newt 'find . \! -type d -mtime -7 -print | grep -v '\''\.[aoe]$'\'
alias newt2 'find . \! -type d -mtime -14 -print | grep -v '\''\.[aoe]$'\'
alias newt3 'find . \! -type d -mtime -21 -print | grep -v '\''\.[aoe]$'\'
alias newt4 'find . \! -type d -mtime -31 -print | grep -v '\''\.[aoe]$'\'
[/code:1:95ec50eff5]Try deleting these.....-Mike

I deleted the last 5 lines in the .cshrc and ran 'cl' or 'mkiraf', the same error occurred. I then ran 'csh -f -x .cshrc' as you suggested and had the output as:umask 022
setenv iraf /iraf/iraf/
switch ( `uname` )
uname
set path = ( . /iraf/iraf/local/bin /sbin /bin /usr/sbin /usr/bin /usr/games /usr/local/bin /usr/local/sbin /usr/X11R6/bin )
breaksw
if ( 0 ) then
So where is the error?
Sorry to mis-identify the time of the post as your local time. Indeed, I generally use IRAF within bash as a normal user. Cheers,
Jianghua

That all looks perfectly normal to me as well. The next file to check is the /etc/csh.cshrc file which is the system default, i.e.[code:1:955d6f18b2]csh -f -c /etc/csh.cshrc[/code:1:955d6f18b2]Also worth noting is whether renaming the ~iraf/.cshrc file so it just doesn't exist has any effect, i.e. if it then works it points to an error in that file, if is still fails it's something else.-MikeP.S. Posting times are UT

Even root does not have the right to execute 'csh -f -c /etc/csh.cshrc'. So I do not know what's the output of this command.I deleted the .cshrc in the iraf home directory but the problem remained.Jianghua

Sorry, it's "csh -f -x" not "csh -f -c" .....From your bash shell, do you see the same error just typing "csh" to start a C-shell? If so, this is looking more like a problem in the system /etc/csh.cshrc file-Mike

Although I do not know the details, I guess the problem relates to the ati card driver kmod-fglrx from rpm.livna.org. The driver is in fact still being tested. I need it to configure the display on my wide-screen monitor. So I downloaded and installed it. Then I uninstall the driver and everything goes right! Thank you very much, mike!Jianghua
