QT 5.2.0 for Windows and Android on same system possible (Windows 64 Bit)?

[capiman]

Hello,

I want to develop with QT 5.2.0 for Windows as well as for Android
on the same system. My computer is capable of running 64 bit software,
but as far as I have seen QT 5.2.0 for Android is only available as 32 bit version.
For a single variant it is no problem.

Is it possible at all to mix two installations of QT 5.2.0?
Or is one version overwriting, replacing, crashing the other?
Must I choose 32 bit version both time? It this combination working?

In general would it also be possible to cross compile
a QT 5.2.0 application on Windows (or whatever...),
which can be used on Linux or Mac?
Or must I compile each application on its own system?

Best regards,

Martin

Hi and welcome to devnet,

You can have both Windows and Android Qt installed in parallel, that is not a problem.

Cross-compilation for OS X is not possible at all. Cross-compiling to linux is tricky but doable. The most common way these days is to use a virtual machine with linux on it (nothing beats compiling on the target system)

Many thanks for your answer!
I have meanwhile installed both QT 5.2.0 version.
It was installed in two different directories
(one c:\Qt\Qt5.2.0 and the Android version in c:\Qt\Qt5.2.0-Android).

I can see Android in Qt Creator, but was not yet able to create a project,
which creates an Android APK.

I found meanwhile a point, which I think is a problem:
(sorry, I have German version, try to translate what I see)

I select

Extras (in Main Menu)->Properties->Properties and Execution (in left menu with icons and text)->QT Versions.

There the installed/found QT Versions are listed.
Qt 5.2.0 MinGW 32 bit seems to be ok,
but the above 3 Android Version are not ok, have a red "!" in front.
When clicking on one of the (erronous) entries,
it tells me it has no compiler.

Looking into the (displayed) path, e.g.
c:\Qt\Qt5.2.0-Android\5.2.0\android_armv7\bin
c:\Qt\Qt5.2.0-Android\5.2.0\android_armv5\bin
c:\Qt\Qt5.2.0-Android\5.2.0\android_x86\bin\

I see e.g. the following content:

The others look similar, similar files.
But there is no compiler like gcc or similar in it?

Do I need to install them separately? Which one (from where downloaded)?

BTW:
During tests with Qt Android I started Qt for Windows.
It worked (at least opened), but I was not more able to compile.
Green arrow on left side to compile and execute was greyed out...

BTW2:
During my tests with Qt Android, I was able to compile,
but the created executable runs under Windows
and I found no *.apk.
Bug or feature that Qt Android created a Windows Executable?
It is a nice thing to first be able to see output on Windows,
but is Qt Android only created when doing certain action
(e.g. only in Release mode)?

Did you install the SDK/NDK for Android ?
