F14 - attempt to install XAMPP, run "chmod 764 /opt", get "ERROR: ld.so..."

[Irfan_A]

Hi, I want to copy folder to /opt because I want to try Joomla! on XAMPP. Based on guidance on XAMPP website : http://www.apachefriends.org/en/xampp-linux.html#377, XAMPP will be installed on /opt folder. So, I search on this forum for solution, but I have a problem after run "chmod 764 /opt" from this post : http://forums.fedoraforum.org/archiv...p/t-61663.html. This cause all of apps on /opt folder couldn't be run, like LibreOffice, Acrobat Reader, etc.

This displayed every time when I run Terminal:

ERROR: ld.so: object 'libesets_pac.so' from /etc/ld.so.preload cannot be preloaded: ignored.
ERROR: ld.so: object 'libesets_pac.so' from /etc/ld.so.preload cannot be preloaded: ignored.
ERROR: ld.so: object 'libesets_pac.so' from /etc/ld.so.preload cannot be preloaded: ignored.
ERROR: ld.so: object 'libesets_pac.so' from /etc/ld.so.preload cannot be preloaded: ignored.
ERROR: ld.so: object 'libesets_pac.so' from /etc/ld.so.preload cannot be preloaded: ignored.

My questions :
1) How to I fix this?
2) What is the mean of "chmod 764 /opt" ? It same as "chmod -rwxrw-r-- /opt", so I should can read, write, and execute on /opt folder?
3) How do you install XAMPP on Fedora? Do you install on /opt folder?

Thank you... .

I would start by resetting permissions on /opt back to normal: chmod 755 /opt

What is the mean of "chmod 764 /opt" ? It same as "chmod -rwxrw-r-- /opt"
----------------------------
764 is -rwxrw-r--
The latter is 741.

Both are wrong, and should be 755 /opt
or
-rwxr-xr-x /opt

Its octal - base 8
rwx -
Read =4 , write=2 , execute=1 -> 421 = 7
for each of the owner, group, other categories.

XAMPP should automatically install to the /opt folder

You may need to be logged in as root to do it, though.
At least that is what I do here when working on server items.
