Qt Sensors Qml compilation error

Question

I look at an example application for Qt Sensors that comes with qt, and I ran it on Windows without errors, but as soon as I try to put it on my Android, I get this compilation error.

10:41:51: Running steps for project qmlqtsensors...
10:41:51: Configuration unchanged, skipping qmake step.

I looked at Google to no avail. Can someone help me with this problem?

Answer 1

It seems that the error, or at least one of them, is due to the fact that the path to the qmlqtsensors file is too long.

The full path of C:C:\Qt\Qt5.2.1\5.2.1\android_x86\examples\sensors\build-qmlqtsensors-Android_for_armeabi_v7a_GCC_4_8_Qt_5_2_1-Release\android-build\Qt\Qt5.2.1\5.2.1\android_armv7\examples\qtsensors\qmlqtsensors is too long.

Try compiling and running the project elsewhere with a shorter path.

Answer 2

I get an error in this example (and had the same thing in the previous examples a while ago).

, Makefile "" . , :     mkdir C: $(INSTALL_ROOT)/........

, $(INSTALL_ROOT) , , :     mkdir C: C:/Qt/.......

Makefile, "C: $(INSTALL_ROOT)" "$ (INSTALL_ROOT)". , , .
