Я пришел к выводу, что `ldd -r' не очень хорошо подходит для этой
проверки. Есть несколько проблем, связанных со спецификой проверки
в %buildroot. В частности, ldd не позволяет "перебить" rpath.
Вот альтернативная реализация `ldd -r'.
RTLD=/lib/ld-linux.so.2
RTLD_libpath=/lib:/usr/lib:/usr/X11R6/lib
elf1_libpath()
{
local elf="$1"
local libpath="$RTLD_libpath"
[ -z "$LD_LIBRARY_PATH" ] ||
libpath="$LD_LIBRARY_PATH:$libpath"
[ -z "$RPM_FINDPROV_LIB_PATH" ] ||
libpath="$RPM_FINDPROV_LIB_PATH:$libpath"
local info= rpath=
info="$(objdump -p "$elf")" || return
rpath="$(echo "$info" |awk '($1=="RPATH"){printf "%s:", $2}')"
[ -z "$rpath" ] ||
libpath="$rpath$libpath"
if [ -n "$RPM_BUILD_ROOT" ]; then
local BR_libpath= path= IFS=:
for path in $libpath; do
BR_libpath="$BR_libpath:$RPM_BUILD_ROOT$path"
done
libpath="${BR_libpath#:}:$libpath"
fi
[ "$libpath" = "$RTLD_libpath" ] ||
echo "${libpath%%:$RTLD_libpath}"
}
elf1_ldd()
{
local elf="$1" libpath=
libpath="$(elf1_libpath "$elf")" || return
LD_TRACE_LOADED_OBJECTS=1 LD_WARN=yes LD_BIND_NOW=yes LD_VERBOSE= \
"$RTLD" --library-path "$libpath" --inhibit-rpath "$elf" "$elf"
}
