Why I can't store LD_LIBRARY_PATH in profile ?


Hi,

I can't store LD_LIBRARY_PATH in /etc/profile. After restart the variable is empty. All OK with any other variable, for example INFORMIXDIR, but not with LD_LIBRARY_PATH.
If I use EXPORT command in the console all OK. I'm using Ubuntu 10.04. What's wrong?

Are you sure you add:
Code:
export LD_LIBRARY_PATH=/some/path:/some/other/path
in /etc/profile and it's not unset by some settings in .profile?

yes, I'm sure. It looks like something unset this variable. I also tried to set in .profile, the same result. Any other variable works fine.

Just tested on an Ubuntu server (no X) and it works. In fact I can set it either through /etc/profile, /etc/bash.bashrc or in a file /etc/profile.d/ld_library.sh

Reading this, looks like it's unset when gdm starts. There are 2 workarounds (posts #17 and #21) there, so try any of them and see if you manage to keep the variable set.

LD_LIBRARY_PATH is still empty in xterm. How to store the variable for xterm too?
PATH is OK in xterm but not LD_LIBRARY_PATH.

Does this happen only for xterm, or for other terminals too? I don't get it. If the variable is set globally, how can it be unset per application.
Anyway you can create an alias
Code:
alias xterm='LD_LIBRARY_PATH=/some/path:/other/path /usr/bin/xtern'

If you want to set it only for you, you can put it in ~/.bashrc. In general in /etc/bash.bashrc, but you should check if it works

thanks for the idea, but it doesn't work for me

I've added

alias xterm='LD_LIBRARY_PATH=/mypath1:/mypath2 /usr/bin/xterm'

to ~/.bashrc

LD_LIBRARY_PATH still empty in xterm.
Any other variables are OK - PATH, ORACLE_HOME, etc.

Run either one:
Code:
chmod -s /usr/bin/xterm
chmod 755 /usr/bin/xterm
