[OE-core] qt4-embedded - tweaking configure options to reduce binary size

[John Stirling]

I'm attempting to cut out some features to reduce our binary size a bit.

I added a .bbappend file (to overwrite QT_CONFIG_FLAGS setup in qt4.inc
etc) -

PRINC := "${@int(PRINC) + 1}"

QT_CONFIG_FLAGS := "-embedded $QT_ARCH \
                    -qtlibinfix E \
                    -plugin-gfx-transformed -plugin-gfx-qvfb
-plugin-gfx-vnc -plugin-gfx-directfb \
                    -plugin-mouse-tslib -qt-mouse-pc -qt-mouse-qvfb
-qt-mouse-linuxinput \
                    -qt-kbd-tty -qt-kbd-linuxinput \
                    -DQT_KEYPAD_NAVIGATION \
                    -release -no-cups -reduce-relocations \
                    -shared -no-nas-sound -no-nis \
                    -system-libjpeg -system-libpng -system-libtiff
-system-zlib \
                    -no-pch -stl -glib \
                    -no-rpath -silent \
                    -qdbus \
                    -no-qt3support \
                    -no-webkit \
                    -no-phonon \
                    -no-sql-ibase -no-sql-mysql -no-sql-psql -no-sql-odbc
-plugin-sql-sqlite -system-sqlite -no-accessibility -no-sm \
                    -exceptions -no-fast"


When rebuilding I'm seeing the amended options appear in run.do_configure
but it doesn't seem to make any difference to the binary sizes.

I expect some form of finger trouble at this end but does anyone have any
advice on this ?

My current Qt libs are -

-rwxr-xr-x root       root          2993840 ./usr/lib/libQtCoreE.so.4
-rwxr-xr-x root       root           439440 ./usr/lib/libQtDBusE.so.4
-rwxr-xr-x root       root          2882400 ./usr/lib/libQtDeclarativeE.so.4
-rwxr-xr-x root       root          8787152 ./usr/lib/libQtGuiE.so.4
-rwxr-xr-x root       root          1090028 ./usr/lib/libQtNetworkE.so.4
-rwxr-xr-x root       root          2108856 ./usr/lib/libQtScriptE.so.4
-rwxr-xr-x root       root           205388 ./usr/lib/libQtSqlE.so.4
-rwxr-xr-x root       root           214292 ./usr/lib/libQtXmlE.so.4
-rwxr-xr-x root       root          3519484 ./usr/lib/libQtXmlPatternsE.so.4

Thanks
