I have been using tcsh for quite some time, both on a laptop running Ubuntu and a remote server running Slackware 11. No problem whatsoever. Now I am compiling and installing tcsh on a brand new Slackware 13 box and when I run tcsh I get this error:

Unknown colorls variable 'ca'

or

Unknown colorls variable 'hl'

I didn't have this problem in Slackware 11, why is it happening now?

So I tried the official Slackware package for tcsh. It works, but it's tcsh 6.15.00. Tcsh is at 6.17.00, which runs fine on my Slackware 11 box.

I investigated the problem on Google and all reports seem to refer to Fedora, some to Mandriva. Many of the threads, across several forums and sites, point to this LinuxQuestions thread:

http://www.linuxquestions.org/questi...-%60ca-659523/

But none of that is helping me with my problem. Does anyone here know how to fix this?

Investigating further, I found that I can go from Bash to Tcsh without the error if I unset the LS_COLORS variable:

I can also add that line to my .bash_profile file, the effect is the same.

But that is not what I want. I want tcsh to be my login shell. Adding that line to .bash_profile or .tcshrc doesn't solve the problem. I can use tcsh as my login shell, but I get the error and my .tcshrc is not processed, so I lose all the customizations.

This sucks.

Searched more and came across this thread:

I applied the patch and seems to have solved the problem. Will see. Marking as SOLVED.
