    Hi, was a solution for this ever found? I'm getting the same error. Just installed 5.4. New clean project. Getting ":-1: error: File Makefile.Release doesn't exist." Looking in the build dir, no such file is created (only "Makefile", not "Makefile.Release" or "Makefile.Debug".

    Thank you for advices (actually last link is brilliant). I checked Java interaction and it's seems really easy to integrate Java parts in QT. One thing still is not clear for me - is it possible to keep and continue Java development for other members involved intros project. Probably it means - can they create Android views and intercept user intercation from that views ?

    Hi and welcome to devnet, You can use QT_DEBUG_PLUGINS=1 to see what happens with the plugins. However my first guess would be that ubuntu touch doesn't have a backend yet for Qt.

    In the folder where you originally installed Qt you should have several folders with name corresponding to the platform and compiler used. Just point the newly created Qt version to the qmake in your android Qt installation

    It should rather be: @$(COPY) $${SRCDIR}/file.h $${DESTDIR}@ So you don't have to have a similar line for each platform

    If anyone got any phonesimulator-debug error (64, 65, 66) it is because there is something preventing xcode from running the build. Try restarting the computer. It's what helped me/.

    There are still several installers available. You can see them if you click on the "View All Downloads" link. They are separated because some people don't want to do mobile development so it's counter productive to have to download e.g. 1.7GB of data if the 599MB is enough for what you want.

    Hello, If you copy database from resource to folder in the internal storage, you need to change permission, because when you copy the file (database) is only to read.

    This is called "excellent" support. Thank you very much kuschky (i dont know your real name) and Sam! Having both help, I have cross compiled "uitools" for the ARM target as Sam mentioned and linked the library by the way that Kuschky mentioned. With this, My application running on target is able to simulate the events. Thank you very much!!! Best Regards, Kumar
