    After spending more time with this. I finally just deleted all the project files. Cleaned, did QMake and rebuilt. The problem went away. I am finding that building ios applications with Qt (especially with openGL) is a bit of a crap shoot. One minute, everything builds fine. The next, nothing is working. Sometimes the debugger is working. Others not. Sometimes it works to deploy from Qt. Other times it fails and I have to run out of Xcode. sigh.

  • QMAKE_BUNDLE_DATA Where do the files go in the ios bundle? [SOLVED]

    After a >>SUBSTANTIAL<< amount of trial and error, I finally figured out where the he!@ my bundle data went: First, my QMAKE_BUNDLE_DATA setup was wrong. The correct setup was: @packets.files = $$files($(HOME)/fast/packets/*.gly) packets.path = packets textures.files = $$files($(HOME)/fast/textures/*.tga) textures.path = textures QMAKE_BUNDLE_DATA += packets textures @ That was a big blunder on my part. But the second was more difficult to track down. Here's the code to get the proper path to the bundle data on ios: @ QString dloc = (QStandardPaths::standardLocations(QStandardPaths::HomeLocation).first()); dloc += "/textures" or dloc == "/packets" @ My bundle content was buried under two sub directories off QStandardPaths::HomeLocation called textures and packets. Just remember, on iOS, the device IS case sensitive. On my mac, it is NOT case sensitive. That can lead to some confusion on devices. Well, that is a couple of hours of my life I'd sure like back!

    You need to register your C++ interface via JNI. You may find example code at: https://github.com/benlau/qtandroidexamplecode/tree/master/qtandroidrunner

Now, when I build my app, I have error message in "Compile Output": ... BUILD FAILED /home/user/projects/android/android-sdk-linux/tools/ant/build.xml:653: The following error occurred while executing this line: /home/user/projects/android/android-sdk-linux/tools/ant/build.xml:698: null returned: 1 Total time: 0 seconds Building the android package failed! ... 17:14:52: The process "/home/user/Qt5.4.0/5.4/android_armv7/bin/androiddeployqt" exited with code 14. Error while building/deploying project positioning (kit: Android for armeabi armv6 (GCC 4.9, Qt 5.4.0)) When executing step "Build Android APK" Can you help me? How can I compile the app for armv6 (for run it on HTC Wildfire S). Thanks for your reply.

    Hi, It's only required to build Qt. The tslib support is done through a plugin, so AFAIK, it should not be a problem
