Is it possible to build QtMqtt on Windows 10 for Android ARM v7?

Matthias Klein

Hello,

I try to build the QtMqtt module for Android, but failed.

I have the following environment:

Windows 10 Host
Qt 5.12.3 from the Online Open Source installer
Android NDK 19.2.5345600 with SDK 26.1.1 (installed with the Android Studio installer)

I cloned the 5.12 branch and tried the following in a "cmd" shell:

set ANDROID_NDK_ROOT=C:\Users\MAK\AppData\Local\Android\Sdk\ndk-bundle
C:\Qt\5.12.3\android_armv7\bin\qmake.exe

But it stops directly with the following error:

Project ERROR: Cannot run target compiler 'C:\Users\MAK\AppData\Local\Android\Sdk\ndk-bundle/toolchains/llvm/prebuilt/windows/bin/clang++'. Output:
===================
===================
Maybe you forgot to setup the environment?

How can I setup the environment?

Thanks a lot for every tip!

@Matthias-Klein said in Is it possible to build QtMqtt on Windows 10 for Android ARM v7?:

C:\Users\MAK\AppData\Local\Android\Sdk\ndk-bundle/toolchains/llvm/prebuilt/windows/bin/clang++

Does this path exist and can you call the compiler manually?

Sorry, that I answer so late, but I didn't get a notification.

The path does not exist.

The following path does exist, but where should I adjust this?: C:\Users\MAK\AppData\Local\Android\Sdk\ndk-bundle\toolchains\llvm\prebuilt\windows-x86_64\bin\clang++.exe

Hi and welcome to devnet,

One maybe simpler way to do that would be to open the module in Qt Creator and build it using the Android Kit.
