[ILUG] TOTD: ld's rpath option...

[Paul Jakma]

Hi,

Handy tip if you want to install a shared library to a strange 
location but want your application to be able to find it without fuss 
(ie without having to add $strange_location to /etc/ld.so.conf): use 
the -rpath option of ld to specify an absolute path to the library or 
the directory it is located in, eg -rpath /usr/lib64/strange_dir. 
This'd result in:

# ldd app | grep strange_location
          libwhatever.so.0 => /usr/lib64/strange_dir/libwhatever.so.0 (0x0000003c1c400000)

This might be useful in order to avoid cluttering a standard lib 
directory even further, or for shipping your own version of a common 
library (though, what happens in latter case if system /also/ has 
that library, i dont know).

regards,
