You can, in /etc/profile, add a line like this:


where "/usr/local/lib" is the directory (NOT the name of the library) where the library(ies) reside that you want on your path. Note that /usr/local/lib is already (in most cases) included in the default library search path, so you don't need to add that, this is just an example. On the other hand, if the library file you need (the extension is ".a" or ".so") is in /usr/local/lib, well, add that to LD_LIBRARY_PATH (because your system doesn't default that way). Don't overdo this, just add what you need and nothing else.

You do this in /etc/profile so any user logged in on the system will have this environment variable defined (and you only have to do it once in one place and you've done your day's work). You must log off and log back on for the change to take effect -- /etc/profile is read once by all shell programs at login -- and you must be root or use the su utility to edit that file. Do the entry somewhere after the setting(s) that may be there for PATH (look at the comments in the file to figure out where to add it, and, if there is already an entry for LD_LIBRARY_PATH, add the new one as above below the last entry.

After you've done editing, logged off and back on, check what you did with


and see that what you did actually is what you wanted (obviously, if it's not, correct it).

The form is important: be sure to use the ${LD_LIBRARY_PATH} form, and separate any additional directory entries with a colon (as shown). The "LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/usr/local/lib" form says, "assign whatever value that may already exist, then append the new value to it." You can append one or more values on one line or you can do this on multiple lines (if you need to add more paths that just this one); the format says to append, not replace, and multiple lines are just fine.

Hope this helps.
