[SOLVED] Why I can't store LD_LIBRARY_PATH in profile ?

shaen777 · 04-13-2011, 06:01 AM

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.

Dear bathory, thank you for your prompt and quick response. Post 17 from your link resolved my problem.

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'

where can I type it? in the console or store in some file? I checked only xterm and terminal. terminal is OK.

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.

Another ubuntu "bug"! Solution on post #3 (remove suid/sgid)

shaen777 · 04-14-2011, 05:46 AM

thanks for the link, how can I remove the s-flags from xterm?

bathory · 04-14-2011, 06:21 AM

Run either one:

Code:

chmod -s /usr/bin/xterm
chmod 755 /usr/bin/xterm
