android: QT += GammaRayProbe doesn't work

[fmeerkoetter]

I want to use Gammaray with an Android device. I've followed the instructions outlined here: https://github.com/KDAB/GammaRay/blob/master/Install.txt

Build on Android: $ mkdir android-build $ cd android-build $ export ANDROID_NDK=~/path/to/android-ndk $ cmake -DCMAKE_TOOLCHAIN_FILE=../cmake/Toolchain-android.cmake \ -DGAMMARAY_PROBE_ONLY_BUILD=true \ -DCMAKE_PREFIX_PATH=/android/qt5/install/path \ -DCMAKE_INSTALL_PREFIX=/android/qt5/install/path .. $ make [-j CPU_NUMBER+2] $ make install

The make install step completes successfully (2.7 branch).

Next I've created a simple qmake test project and added "android: QT += GammaRayProbe" to it as outlined in the documentation.

When I now run qmake I always get: Project ERROR: Unknown module(s) in QT: GammaRayProbe

From poking around in the mkspec files of my Qt5.8 install I wonder how this is supposed to work. The make install step doesn't install a .pri file that would allow QT += GammaRayProbe to work.

What am I doing wrong?

[vkrause]

The problem is in probe/CMakeLists.txt, with GAMMARAY_PROBE_ONLY_BUILD set it doesn't install the pri file. Still need to track down why, I'd guess to avoid some install conflicts in multi-probe setups. Not setting GAMMARAY_PROBE_ONLY_BUILD (and if needed rather setting GAMMARAY_BUILD_UI=OFF) might be a viable workaround.

[fmeerkoetter]

I can confirm this workaround. Thank you very much!

Fixed the build instructions.
