# 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
|
|
