LD_LIBRARY

Defines search paths to find shared libraries on UNIX™ platforms.

The LD_LIBRARY_PATH environment variable defines the list of search paths for shared libraries loaded by the dynamic linker on UNIX platforms.

On some operating systems, the environment variable defining the shared library search path may have a different name.

On a system where a 32-bit and a 64-bit environment coexist, you may need to set LD_LIBRARY_PATH_64 to execute the 64-bit programs.
On HP/UX, set SHLIB_PATH.
On AIX^®, set LIBPATH.
On Mac OS X^®, the usage of DYLD_LIBRARY_PATH is discouraged. Therefore, shared libraries that are not part of the Genero runtime system (such as database client libraries) must be found in the standard system directories (/usr/lib, /usr/local/lib)
