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