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# Cygwin uses $PATH 62# Mac OS X uses $DYLD_LIBRARY_PATH 63# 64# Other cases not handled by this script: 65# 66# AIX uses $LIBPATH 67# IRIX64 may use $LD_LIBRARY64_PATH or $LD_LIBRARYN32_PATH 68# Solaris may use $LD_LIBRARY_PATH_64 69# 70CDPATH= 71# 72# Make sure that we use the PATH that was set in run_tic.sh 73if test -n "$SHLIB_PATH" ; then 74 PATH=$SHLIB_PATH 75 export PATH 76fi 77 78# Find the lib-directory for this build tree 79q="" 80for p in lib ../lib ../../lib ../../../lib 81do 82 if test -d $p; then 83 q=`cd $p; pwd` 84 break 85 elif test -f configure && test ! -d ../$p ; then 86 break 87 fi 88done 89 90# Set the environment variable. 91if test -n "$q" ; then 92 system= 93 if test -n "$SHLIB_HOST" ; then 94 system="$SHLIB_HOST" 95 elif test -n "$PATHEXT" ; then 96 system=cygwin 97 elif test -n "$LIBRARY_PATH" ; then 98 system=beos 99 elif test -n "$DYLD_LIBRARY_PATH" ; then 100 system=darwin 101 elif test -n "$LD_LIBRARY_PATH"; then 102 system=unix 103 else 104 for r in $q/*.* 105 do 106 if test -f "$r" 107 then 108 case $r in 109 *.dll) 110 system=cygwin 111 ;; 112 *.dylib) 113 system=darwin 114 ;; 115 esac 116 fi 117 test -n "$system" && break 118 done 119 fi 120 121 case .$system in 122 .cygwin*) 123 variable=PATH 124 ;; 125 .beos*) 126 variable=LIBRARY_PATH 127 ;; 128 .darwin*) 129 variable=DYLD_LIBRARY_PATH 130 ;; 131 *) 132 variable=LD_LIBRARY_PATH 133 ;; 134 esac 135 136 eval 'test -z "$'$variable'" && '$variable'=":"' 137 eval $variable'="$q:$'$variable'"' 138 eval 'export '$variable 139fi 140 141eval "$*" 142
