The drawback is that then the environment 41169689Skan# variable has to be set to run the programs within this directory tree. 42169689Skan# 43169689Skan# For Linux (and other systems using the GNU loader), we can use the rpath 44169689Skan# directive, which embeds the pathname of the library within the executable. 45169689Skan# Using the Linux loader's rpath directive introduces a constraint, since 46169689Skan# it's embedded into the binary, and means that the binary cannot be moved 47169689Skan# around (though it'll work if the $exec_prefix convention that puts the bin 48169689Skan# and lib directories under the same parent is followed). 49169689Skan# 50169689Skan# Using the actual soname (e.g., ../lib/libncurses.so) alone, is a more 51169689Skan# flexible solution; you can link without having to set the environment 52169689Skan# variable, and on some systems (IRIX) you can even run the resulting binaries 53169689Skan# without setting LD_LIBRARY_PATH. 54169689Skan# 55169689Skan# Using a conventional link, with -L and -l options on Linux results in a 56169689Skan# statically linked executable, which we don't want at all. 57169689Skan# 58169689Skan# Special cases: 59169689Skan# 60169689Skan# BeOS R4.5 uses $LIBRARY_PATH rather than $LD_LIBRARY_PATH. 61169689Skan# Cygwin uses $PATH 62169689Skan# Mac OS X uses $DYLD_LIBRARY_PATH 63169689Skan# 64169689Skan# Other cases not handled by this script: 65169689Skan# 66169689Skan# AIX uses $LIBPATH 67169689Skan# IRIX64 may use $LD_LIBRARY64_PATH or $LD_LIBRARYN32_PATH 68169689Skan# Solaris may use $LD_LIBRARY_PATH_64 69169689Skan# 70169689SkanCDPATH= 71169689Skan# 72169689Skan# Make sure that we use the PATH that was set in run_tic.sh 73169689Skanif test -n "$SHLIB_PATH" ; then 74169689Skan PATH=$SHLIB_PATH 75169689Skan export PATH 76169689Skanfi 77169689Skan 78169689Skan# Find the lib-directory for this build tree 79169689Skanq="" 80169689Skanfor p in lib ../lib ../../lib ../../../lib 81169689Skando 82169689Skan if test -d $p; then 83169689Skan q=`cd $p; pwd` 84169689Skan break 85169689Skan elif test -f configure && test ! -d ../$p ; then 86169689Skan break 87169689Skan fi 88169689Skandone 89169689Skan 90169689Skan# Set the environment variable. 91169689Skanif test -n "$q" ; then 92169689Skan system= 93169689Skan if test -n "$SHLIB_HOST" ; then 94169689Skan system="$SHLIB_HOST" 95169689Skan elif test -n "$PATHEXT" ; then 96169689Skan system=cygwin 97169689Skan elif test -n "$LIBRARY_PATH" ; then 98169689Skan system=beos 99169689Skan elif test -n "$DYLD_LIBRARY_PATH" ; then 100169689Skan system=darwin 101169689Skan elif test -n "$LD_LIBRARY_PATH"; then 102169689Skan system=unix 103169689Skan else 104169689Skan for r in $q/*.* 105169689Skan do 106169689Skan if test -f "$r" 107169689Skan then 108169689Skan case $r in 109169689Skan *.dll) 110169689Skan system=cygwin 111169689Skan ;; 112169689Skan *.dylib) 113169689Skan system=darwin 114169689Skan ;; 115169689Skan esac 116169689Skan fi 117169689Skan test -n "$system" && break 118169689Skan done 119169689Skan fi 120169689Skan 121169689Skan case .$system in 122169689Skan .cygwin*) 123169689Skan variable=PATH 124169689Skan ;; 125169689Skan .beos*) 126169689Skan variable=LIBRARY_PATH 127169689Skan ;; 128169689Skan .darwin*) 129169689Skan variable=DYLD_LIBRARY_PATH 130169689Skan ;; 131169689Skan *) 132169689Skan variable=LD_LIBRARY_PATH 133169689Skan ;; 134169689Skan esac 135169689Skan 136169689Skan eval 'test -z "$'$variable'" && '$variable'=":"' 137169689Skan eval $variable'="$q:$'$variable'"' 138169689Skan eval 'export '$variable 139169689Skanfi 140169689Skan 141169689Skaneval "$*" 142169689Skan
