The drawback is that then the environment 41# variable has to be set to run the programs within this directory tree. 42# 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). 49# 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. 54# 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. 57# 58# Special cases: 59# 60# BeOS R4.5 uses $LIBRARY_PATH rather than $LD_LIBRARY_PATH. 61 62# 63# Make sure that we use the PATH that was set in run_tic.sh 64# 65if test X$NEWPATH != X ; then 66 PATH=$NEWPATH 67 export PATH 68fi 69 70q="" 71for p in lib ../lib 72do 73 if test -d $p; then 74 q="$p" 75 fi 76done 77if test -n "$q" ; then 78 if test -n "$LD_LIBRARY_PATH"; then 79 LD_LIBRARY_PATH="$q:$LD_LIBRARY_PATH" 80 elif test -n "$LIBRARY_PATH" ; then 81 LIBRARY_PATH="$q:$LIBRARY_PATH" 82 else 83 LD_LIBRARY_PATH="$q" 84 fi 85 export LD_LIBRARY_PATH 86fi 87eval "$*" 88
