Hi, I upgraded my mini2440 with Qt in version 4.6.3 and I´m surprised with RAM consumption. An very basic application such as analogclock from examples occupies more than 18M of memory. I have tried compile it in static mode, but RAM saving was not very significant (about 3M) and flash footprint was approx. 50 times bigger (24k vs 12M). I´m using stock kernel and rootfs, Qt was compiled with following options: ./configure -prefix /usr/local/Qt -fast -pch -no-qt3support -qt-sql-sqlite -no-libtiff -no-libmng -qt-libjpeg -qt-zlib -qt-libpng -qt-freetype -no-openssl -nomake examples -nomake demos -nomake tools -optimized-qmake -no-phonon -no-nis -no-opengl -no-cups -no-largefile -no-xcursor -no-xfixes -no-xrandr -no-xrender -no-xkb -no-sm -no-xinerama -no-xshape -no-webkit -no-separate-debug-info -xplatform qws/linux-arm-g++ -embedded arm -depths 16,32 -no-qvfb -qt-gfx-linuxfb -qt-gfx-transformed -no-gfx-qvfb -no-kbd-qvfb -no-mouse-qvfb -opensource -confirm-license -qt-mouse-tslib -I/usr/local/tslib/include -L/usr/local/tslib/lib Are there any ways to minimize RAM footprint significantly? What is your RAM consumption of Qt apps ??? Thanks you for your answers. martyy
Qt application RAM usage
How do you measure the 18 MiB of memory your program is using? As Linux is using the MMU is can assign virtual only memory to the process.
