Qt-app won't build since libQtUiTools not included in staging

Qt-app won't build since libQtUiTools not included in staging

[Erik Botö]

Hi,

I'm writing a bitbake recipe for a QT-app that tries to link against
libQtUiTools but it fails with:

/bin/ld: cannot find -lQtUiTools

I think this is because this file is not in the staging environment (I'm
using qt-embedded-4.4.3 for building qt). I checked the qt_staging.inc file
and is seems that all .la libraries gets staged but libQtUiTools is a .a
file and not included in the staging environment.

Is this intentional or should it be included?

Best regards,
Erik

Looking at qt_staging.inc:

     for i in libQtAssistantClient${QT_LIBINFIX} \
		libQtDesignerComponents${QT_LIBINFIX} \
		libQtUiTools${QT_LIBINFIX} \
		libQtDesigner${QT_LIBINFIX}
     do
         sed -i -e "s,-L${libdir},-L${STAGING_LIBDIR},g" $i.prl || true
         cp ${STAGE_TEMP}/${libdir}/$i.prl ${STAGING_LIBDIR} || true
         sed -i -e 
"/^dependency_libs=/s,-L${libdir},-L${STAGING_LIBDIR},g" $i.la || true
         cp ${STAGE_TEMP}/${libdir}/$i.la  ${STAGING_LIBDIR} || true
         oe_libinstall -C ${STAGE_TEMP}/${libdir} -so $i 
${STAGING_LIBDIR} || true
         oe_libinstall -C ${STAGE_TEMP}/${libdir} -a $i 
${STAGING_LIBDIR} || true
     done

So it attempts to install to .so (oe_libinstall -so) and the .a 
(oe_libinstall -a) to the staging dir.

If you're building qt/e you should link against QtUiTools${QT_LIBINFIX} 
(expands to QtUiToolsE in your case), not QtUiTools. AIUI 'inherit 
qtopia4core' should take care of all that for you.

Hi again!

When I build qt-embedded I get the "E" suffix on all libraries but
QtUiTools. If I enter the workdir for qt-embedded and lists the content of
the lib-dir I have all the .la libraries with the E suffix, like
"libQtGuiE.la" etc. But the QtUiTools file is called "libQtUiTools.a"
without the "E". So if qt_staging.inc expects the suffix to be there I guess
it won't find the file?

Is the QtUiTools some kind of exception, or should it also be suffixed with
an E?

Best regards,
Erik

I would class it as a bug and make the QT people look at it, Holger?
