Ive run into a fairly odd issue on a few servers running RHEL 5.9
For some reason I cant seem to figure out ldconfig looks in /usr/local/etc per default instead of /etc where its suppose to look

[root@myhost ~]# ldconfig
ldconfig: Can't open configuration file /usr/local/etc/ld.so.conf: No such file or directory
[root@myhost ~]# ls /etc/ld.so.conf
/etc/ld.so.conf

[root@myhost ~]# ldconfig -p | head -1
38 libs found in cache `/usr/local/etc/ld.so.cache'
[root@myhost ~]# ldconfig -p -C /etc/ld.so.cache | head -1
653 libs found in cache `/etc/ld.so.cache'

Im guessing its a wrong enviroment setting somewhere

Can anyone tell me how I fix this so ldconfig uses correct default path ?

Are you using the RHEL5.9 glibc package.

On my RHEL5.9 system I don't see the issue you have but the ldconfig and setup are provided by glibc so if you did something odd like install an upstream glibc you may be getting a location other than the 1 RHEL5.9's build expects.

"yum list glibc" to see what version you have installed and what version is available from repository.
