How can i extend default lib search path in ubuntu(in a way that it is also persistent) ? no, I do not want export LD_LIBRARY_PATH based temporary solution, rather some way to extend the default lib search path ?

while google-ing, I cam across some info, that in ubuntu the default search path resides in /etc/ld.so.conf.d , but editing libc.conf does not extended the default path.. so i think either i am doing it wrong, or something is missing...

the edited libc.conf looks like... 

# libc default configuration
/usr/local/lib:/path_to_my_libraries/lib

create (as root) a new file in /etc/ld.so.conf.d/ containing, the new path. For example:

sudo echo "/path-to-your-libs/" >> /etc/ld.so.conf.d/your.conf

after that run

sudo ldconfig

No need to change libc.conf.
