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 $LD_LIBRARY_PATH. + +# +# Make sure that we use the PATH that was set in run_tic.sh +# +if test X$NEWPATH != X ; then + PATH=$NEWPATH + export PATH +fi + +q="" +for p in lib ../lib +do + if test -d $p; then + q="$p" + fi +done +if test -n "$q" ; then + if test -n "$LD_LIBRARY_PATH"; then + LD_LIBRARY_PATH="$q:$LD_LIBRARY_PATH" + elif test -n "$LIBRARY_PATH" ; then + LIBRARY_PATH="$q:$LIBRARY_PATH" + else + LD_LIBRARY_PATH="$q" + fi + export LD_LIBRARY_PATH +fi +eval "$*" |
