QT 5.7 with Android GCC 4.8

[lqsa]

I would like to use Google Firebase with an Android application. When downloads the C++ SDK, the readme remarks this:

• Known Issues
  • Android armeabi libraries must be linked with gcc 4.8.

So, I've tried to configure QT to compile with gcc 4.8. To do it, I've created a new Kit on Build & Run configuration. On the Compiler option I've choosed "Android GCC (arm-4.8)".

The project was recompiled with this new Kit, but when the application starts on the Android device, it crashes, with the message that does an illegal action.

If I compile with the default kit (with gcc 4.9), the application starts. Is it possible to compile and run a QT 5.7 application with Android gcc 4.8?

You should build Qt with GCC 4.8 as well

@jsulm When you say "you should build Qt", are you saying that must be recompiled Qt or that if use gcc 4.8 must work?

@lqsa My guess is that you installed Qt for android which was build with a different version of GCC. In this case you should build Qt with GCC 4.8 as well not only your application.
What is the error message exactly?

Ok, thanks.
No message, only crash when start.
