cannot find a library file
 
In the output shown below I am trying to find libelf.so.0

Code:
[root@james aide-0.15.1]# locate  libelf.so.0

[root@james lib64]# ls -al  libelf.so.0
-rwx------ 1 root root 431754 Mar 25 14:14 libelf.so.0

I am trying to find libelf.so.0. The locate command finds it in many place, but not in

/usr/lib64/

where I put it earlier today.

Why is it not finding it in /usr/lib64/ ?

R,

jyunker

PS.


please note the use/lib64/ is in my LD_LIBARY_PATH.

Code:
echo $LD_LIBRARY_PATH
/usr/lib64/:/lib64/:
[root@james lib64]# locate  libelf.so.0
/home/james/.local/share/Trash/files/hpctoolkit-externals-install/libelf/lib/libelf.so.0

but locate libelf.so.0 still does not find it.

? May be update the "locate data base" :

# updatedb

I am sorry. I do not understand what you said.

Please elaborate.

You need to run updatedb so that newly created files are updated in mlocate database. you do that by

Code:
# updatedb
# locate libelf.so.0

you can try find but it will probably take longer. e.g.:
Code:
find /usr/lib64/ -name libelf.so.0

Madhu Desai 03-26-2014 12:02 PM
Or, since you already know the path... you can just use
Code:
# ls /usr/lib64/libelf.so.0
