Running on android

[Abdulmueez]

I have been trying to run qt on my androd phone, but been running into a lot of problems, I have downloaded the prerequisites as instructed but this does not seem to solve anything. I started trying to run examples instead incase the fault was from my own code, but the following is what appears in my general message tab:

Maybe you forgot to setup the environment?

Can someone put me through please?

@Abdulmueez As stated here: https://doc.qt.io/qt-5/android-getting-started.html starting with Qt 5.12 you should use a NDK newer than r10e. So, I suggest to install newer NDK. Starting with Qt 5.12 CLang instead of GCC is required which provided with newer NDKs.

[Abdulmueez]

I have installed the latest version and now while trying to run on my android phone, I get these 2 errors
:-1: error: error: cannot find -lc++
:-1: error: linker command failed with exit code 1 (use -v to see invocation)

[jsulm]

@Abdulmueez Delete build folder, run qmake and rebuild

[Abdulmueez]

The errors don't go away after applying the recommended changes.

I have the above message in my general message tab

Hi,

Why are you trying to compile for WinRT since you want your application to run on Android ?

Also, cl missing usually means that you don't have Visual Studio installed for C++.

[Abdulmueez]

Hmm, I have visual studio installed already, and about compiling for winrt, all I do is click on the compile for android v7a... and then click on run.
Isn't that the right step to follow.

[SGaist]

Did you install all the tools needed for Android development ? Like the SDK and NDK ?

[Abdulmueez]

Yes, I have them both installed.

[SGaist]

Then either you are currently using the wrong Kit or you modified one. The build logs shows that you are trying to build your application with the 64bit Visual Studio 2015 build of Qt.

[Abdulmueez]

No, that's for something else.
These are the messages generated in the issues, general messages and compile output tab
.

[SGaist]

There have been several threads recently about that precise error.

[MajidKamali]

I saw somewhere that ndk 20 is not compatible with Qt. (I can not remember where and why).
It has same errors as you (linker error)
Install ndk 19

[Abdulmueez]

Thanks a lot to everyone, after installing ndk 19, everything seems to work fine.
