# Use this script as a wrapper when running executables linked to shared
# libraries on systems that use the $LD_LIBRARY_PATH variable and don't embed
# the soname's path within the linked executable (such as IRIX), e.g,
#
# shlib knight
#
# Setting LD_LIBRARY_PATH, overrides/supplements the loader's normal search
# path, and works on most systems. The drawback is that then the environment
# variable has to be set to run the programs within this directory tree.
#
# For Linux (and other systems using the GNU loader), we can use the rpath
# directive, which embeds the pathname of the library within the executable.
# Using the Linux loader's rpath directive introduces a constraint, since
# it's embedded into the binary, and means that the binary cannot be moved
# around (though it'll work if the $exec_prefix convention that puts the bin
# and lib directories under the same parent is followed).
#
# Using the actual soname (e.g., ../lib/libncurses.so) alone, is a more
# flexible solution; you can link without having to set the environment
# variable, and on some systems (IRIX) you can even run the resulting binaries
# without setting LD_LIBRARY_PATH.
#
# Using a conventional link, with -L and -l options on Linux results in a
# statically linked executable, which we don't want at all.
#
# Special cases:
#
# BeOS R4.5 uses $LIBRARY_PATH rather than $LD_LIBRARY_PATH.
# Cygwin uses $PATH
# Mac OS X uses $DYLD_LIBRARY_PATH
#
# Other cases not handled by this script:
#
# AIX uses $LIBPATH
# IRIX64 may use $LD_LIBRARY64_PATH or $LD_LIBRARYN32_PATH
# Solaris may use $LD_LIBRARY_PATH_64
