However, gtk-query-immodules application will only be able to parse shared objects from the same ELF class. In order not to have a native package for all the recipes providing an input method, so we can generate the cache file natively, run gtk-query-immodules through qemu emulator. Signed-off-by: Laurentiu Palcu --- Changes in v2: * Used qemu_target_binary() function, in order to obtain the qemu binary corresponding to the current target, as suggested by Phil (thank you, I didn't know that function existed); Thanks, Laurentiu meta/classes/gtk-immodules-cache.bbclass | 21 ++++++++++++++++++++- 1 file changed, 20 insertions(+), 1 deletion(-) diff --git a/meta/classes/gtk-immodules-cache.bbclass b/meta/classes/gtk-immodules-cache.bbclass index 515d28b..72595ee 100644 --- a/meta/classes/gtk-immodules-cache.bbclass +++ b/meta/classes/gtk-immodules-cache.bbclass @@ -2,9 +2,28 @@ # # Usage: Set GTKIMMODULES_PACKAGES to the packages that needs to update the inputmethod modules +DEPENDS =+ "qemu-native" + +inherit qemu + gtk_immodule_cache_postinst() { if [ "x$D" != "x" ]; then - exit 1 + +for maj_ver in 2 3; do + if [ -x $D${bindir}/gtk-query-immodules-$maj_ver.0 ]; then + IMFILES=$(ls $D${libdir}/gtk-$maj_ver.0/*/immodules/*.so) + DYNAMIC_LOADER=$D$(readelf -a $D${bindir}/gtk-query-immodules-$maj_ver.0 |\ + grep "Requesting program interpreter"|sed -e 's/^.*\[.*: \(.*\)\]/\1/') + LIBRARY_PATH=$D${base_libdir}:$D${libdir} + ${@qemu_target_binary(d)} $DYNAMIC_LOADER --library-path $LIBRARY_PATH \ + $D${bindir}/gtk-query-immodules-$maj_ver.0 $IMFILES > $D/etc/gtk-$maj_ver.0/gtk.immodules 2>/dev/null && \ + sed -i -e "s:$D::" $D/etc/gtk-$maj_ver.0/gtk.immodules + + [ $? -ne 0 ] && exit 1 + fi +done + +exit 0 fi if [ ! -z `which gtk-query-immodules-2.0` ]; then gtk-query-immodules-2.0 > /etc/gtk-2.0/gtk.immodules
