The drawback is that then the environment 42# variable has to be set to run the programs within this directory tree. 43# 44# For Linux (and other systems using the GNU loader), we can use the rpath 45# directive, which embeds the pathname of the library within the executable. 46# Using the Linux loader's rpath directive introduces a constraint, since 47# it's embedded into the binary, and means that the binary cannot be moved 48# around (though it'll work if the $exec_prefix convention that puts the bin 49# and lib directories under the same parent is followed). 50# 51# Using the actual soname (e.g., ../lib/libncurses.so) alone, is a more 52# flexible solution; you can link without having to set the environment 53# variable, and on some systems (IRIX) you can even run the resulting binaries 54# without setting LD_LIBRARY_PATH. 55# 56# Using a conventional link, with -L and -l options on Linux results in a 57# statically linked executable, which we don't want at all. 58# 59# Special cases: 60# 61# BeOS R4.5 uses $LIBRARY_PATH rather than $LD_LIBRARY_PATH. 62# Cygwin uses $PATH 63# Mac OS X uses $DYLD_LIBRARY_PATH 64# 65# Other cases not handled by this script: 66# 67# AIX uses $LIBPATH 68# IRIX64 may use $LD_LIBRARY64_PATH or $LD_LIBRARYN32_PATH 69# Solaris may use $LD_LIBRARY_PATH_64 70# 71CDPATH= 72# 73# Make sure that we use the PATH that was set in run_tic.sh 74if test -n "$SHLIB_PATH" ; then 75 PATH=$SHLIB_PATH 76 export PATH 77fi 78 79# Find the lib-directory for this build tree 80q="" 81for p in lib ../lib ../../lib ../../../lib 82do 83 if test -d $p; then 84 q=`cd $p; pwd` 85 break 86 elif test -f configure && test ! -d ../$p ; then 87 break 88 fi 89done 90 91# Set the environment variable. 92if test -n "$q" ; then 93 system= 94 if test -n "$SHLIB_HOST" ; then 95 system="$SHLIB_HOST" 96 elif test -n "$PATHEXT" ; then 97 system=cygwin 98 elif test -n "$LIBRARY_PATH" ; then 99 system=beos 100 elif test -n "$DYLD_LIBRARY_PATH" ; then 101 system=darwin 102 elif test -n "$LD_LIBRARY_PATH"; then 103 system=unix 104 else 105 for r in $q/*.* 106 do 107 if test -f "$r" 108 then 109 case $r in 110 *.dll) 111 system=cygwin 112 ;; 113 *.dylib) 114 system=darwin 115 ;; 116 esac 117 fi 118 test -n "$system" && break 119 done 120 fi 121 122 case .$system in 123 .cygwin*) 124 variable=PATH 125 ;; 126 .beos*) 127 variable=LIBRARY_PATH 128 ;; 129 .darwin*) 130 variable=DYLD_LIBRARY_PATH 131 ;; 132 *) 133 variable=LD_LIBRARY_PATH 134 ;; 135 esac 136 137 eval 'test -z "$'$variable'" && '$variable'=":"' 138 eval $variable'="$q:$'$variable'"' 139 eval 'export '$variable 140fi 141 142eval "$*" 143
