Qt 5.4 & Android - compiler configuration
-
Hi there,
I've just installed Qt 5.4 on my machine running Windows 7 and I cannot configure it to compile for android. I downloaded the JDK, Ant, the SDK as well as the NDK from their official websites, installed them all to C:\ and and set the paths in the options of the Qt Creator appropriately..

Error while building/deploying project calendar (kit: Android for armeabi-v7a (GCC 4.9, Qt 5.4.0))
When executing step "Make"
04:10:54: Elapsed time: 00:03.
@Then I noticed that what the Creator is trying to execute is:
@
C:\android-ndk-r10d/toolchains/arm-linux-androideabi-4.9/prebuilt/windows-x86_64/bin/arm-linux-androideabi-g++
@And I checked for that path and noticed that the path doesn't exist:

Later I checked the other toolchains, none of them contained a similar executable. I also checked the kits and saw the following:

Somehow I don't really understand what I could have done wrong... maybe someone could quickly help me out?
Thank you!

Hey,, I have experienced the same problem, Its simply Qt 5.4 does not work with NDK rev 10 yet, so you need to use NDK 9 that all, because the structure of folders for NDK 10 is different than older editions !
Regards.

Any ideas for when it will work with rev 10?

Why you need Rev 10, rev 9 is working pretty well, I have no idea but I guess it will be in Qt 5.5

Just upgraded my linux system to Qt 5.4, rev 10 was pulled down automatically as well by my package management. Looks like i will have to revert back to rev 9....the joys of running bleeding edge :-)

It will be supported in either 5.4.1 (which has just branched out and should be available within 2-4 weeks), or 5.5 (IIRC, it is almost feature-frozen, so the release is still a long way away).
