Is this a good or bad idea? Why? It wont over right existing libraries. I
ask because I have been adding LD_LIBRARY_PATH statements to some start up
scripts to get them to load properly.

Thanks

Very bad idea. Your applications should be built with correct runtime
link paths or they should be considered broken. Wrapping them
with a shell script that sets LD_LIBRARY_PATH is a reasonable work-around.

Willy nilly mucking around in Sun's directory hierarchies is liable to
break your system.

are you saying:

cd /usr/local
ln -s ../lib lib

or

cd /usr
ln -s local/lib lib

the former is silly and the latter will destroy your system (you lose
/usr/lib/ld.so.1 and you are completely screwed, unless you're a
mega-geek)

Perhaps the OP thinks that Solaris supports BSD style portal/union fs?

Just add /usr/local/lib to LD_LIBRARY_PATH in /etc/profile.

Adding it to /etc/profile won't affect start up scripts in /etc/rc*.d
It will help apps run later by the user though, but I want the apps to run
without worry of the current enviroment, so using the compliler/linker flags
seems like the best solution, just don't understand the switches yet...to
the books I go, yet again....

Thanks guys

Only users with shells that source /etc/profile. csh/tcsh/zsh don't.
