Error about loading shared libraries libyajl.so.2

Hi,

When I do "xl list", there is an error like this:

root@gavin-desktop:~# xl list
xl: error while loading shared libraries: libyajl.so.2: cannot open shared
object file: No such file or directory

I install the yajl followed this message:
http://lists.xen.org/archives/html/xen-users/2012-03/msg00325.html

After that, the module libyajl.so.2 is copied to /usr/local/lib/.

Is there any advice on this problem. Thank you so much.


Best Regards,
Bei Guan

Hi,

This problem is solved now.

My environment is 64-bit ubuntu and xl needs to find libyajl from the
following paths.

   trying file=/lib/libyajl.so.2
   trying file=/usr/lib/libyajl.so.2
   trying file=/lib/x86_64-linux-gnu/tls/x86_64/libyajl.so.2
   trying file=/lib/x86_64-linux-gnu/tls/libyajl.so.2
  ...

However, the actual path of libyajl is /usr/local/lib/libyajl.so.2.0.5
where I just installed into.
So, a symbolic link is enough to solve this problem. Just like this:
# ln -s /usr/local/lib/libyajl.so.2.0.5 /lib/libyajl.so.2


Thanks,
Bei Guan

I'ts probably best to add /usr/local/lib to LD_LIBRARY_PATH instead 
polluting /usr/lib or /lib with symlinks.

Weird that /usr/local/*something* isn't in /etc/ld.so.conf
(/usr/local/lib is there on my Debian system)

In any case it is even better to just install the libyajl packages from
your distro -- there's no requirement to build it from source.

Ian.
