There are many ways of linking and every system uses a different method. From
my (limited) experience, i have noted solaris sysadmins have historically tended
to use LD_LIBRARY_PATH as a primary method for pointing to libs, although
'recently' use of the crle command has become more widespread, which works much
like ldconfig in linux, and LD_LIBRARY_PATH has never seemed to do anything for
me in Linux. Usage of LD_LIBRARY_PATH can cause subtle problems, particularly
if you have multiple library versions, whereas crle/ldconfig way of doing things
is fairly dynamic and you don't have to specify things at compile time.
Personally, on Solaris I always link with -R which hints the resulting binary
towards the runtime lib path - i find this is the only reliable method of
avoiding library clashes.
