Much to my chagrin, we're going back to using ldd directly, as it's otherwise too difficult to account for odd setups, such as idiots wanting to create multilib initramfs images, or more commonly -- a 64 bit kernel on a 32 bit userland. Fortunately, we don't suffer too large a regression in speed compared to the previous implementation. Signed-off-by: Dave Reisner <dreisner@archlinux.org> --- This is one possible solution -- and it's basically what we relied on pre 0.7, but slightly cleaner. There _is_ a small loss of performance, but it's the price we pay. I think this is a preferrably alternative to parsing human formatted output from a tool such as readelf. functions | 10 +++------- mkinitcpio | 18 +----------------- 2 files changed, 4 insertions(+), 24 deletions(-) diff --git a/functions b/functions index 706a64f..c3d79b2 100644 --- a/functions +++ b/functions @@ -204,10 +204,6 @@ add_module() { esac } -_ldd() { - LD_TRACE_LOADED_OBJECTS=1 "$LD_SO" "$@" -} - _add_file() { # add a file to $BUILDROOT # $1: pathname on initcpio @@ -264,10 +260,10 @@ add_binary() { # always add the binary itself _add_file "${dest#$BASEDIR}" "$binary" "$mode" - $LD_SO --verify "$binary" &>/dev/null || return # not a binary! + ldd "$binary" &>/dev/null || return # not a binary! # resolve sodeps - regex='^[[:space:]]*[^/].+ => (.*) \(.*\)' + regex='(/.+) \(0x[a-fA-F0-9]+\)' while read line; do [[ "$line" =~ $regex ]] && sodep=${BASH_REMATCH[1]} || continue @@ -282,7 +278,7 @@ add_binary() { _add_file "${resolved#$BASEDIR}" "$resolved" 755 fi fi - done < <(_ldd "$binary") + done < <(ldd "$binary") return 0 } diff --git a/mkinitcpio b/mkinitcpio index 459c828..71d3e0d 100755 --- a/mkinitcpio +++ b/mkinitcpio @@ -22,7 +22,7 @@ INSTDIR=install PRESETDIR=mkinitcpio.d COMPRESSION=gzip -declare TMPDIR BASEDIR MODULE_FILE GENIMG PRESET COMPRESSION_OPTIONS BUILDROOT LD_SO +declare TMPDIR BASEDIR MODULE_FILE GENIMG PRESET COMPRESSION_OPTIONS BUILDROOT declare NC= BOLD= BLUE= GREEN= RED= YELLOW= declare -i QUIET=1 SHOW_AUTOMODS=0 SAVELIST=0 COLOR=1 declare -a SKIPHOOKS ADDED_MODULES @@ -294,22 +294,6 @@ trap '[[ $FUNCNAME = parse_hook ]] && (( ++builderrors ))' ERR #parse 'global' hook, as defined in ${CONFIG} parse_hook -# resolve the linker and add it -case $CARCH in - i686) LD_SO=("$BASEDIR"/lib/ld-linux.so.?*) ;; - x86_64) LD_SO=("$BASEDIR"/lib/ld-linux-${CARCH//_/-}.so.?*) ;; - *) die "unknown architecture: $CARCH" ;; -esac - -if (( ${#LD_SO[*]} != 1 )); then # uh oh... - die "failed to resolve the location of /lib/ld.so.
