Configure Qt Creator to use Clang with Qt for Android

Question

It seems that GCC is now deprecated and will be removed from the Android NDK; Clang will be used instead. That being said Android NDK will never have support for GCC 5 and no updates will be made in regards to GCC.

That being said I wanted to use Qt for Android with Clang and it seems work has been done in this direction for Qt 5.7.1: https://bugreports.qt.io/browse/QTBUG-50724 but I don't know how to configure Qt Creator to use Clang for the Android configuration and Qt Creator doesn't autodetect the configuration:

Does anyone know how to configure Qt Creator and where the Clang compilers for Android are? It seems that they are somewhere in /Users/user/Library/Android/sdk/ndk-bundle/ but I just can't seem to get it right. I use Qt Creator 4.2.2.

Is it possible to use Qt for Android with Clang?

Answer 1

I have had some success with manually adding C and C++ clang compilers.

Compiler path: /home/david/Android/Sdk/ndk-bundle/toolchains/llvm/prebuilt/linux-x86_64/bin/clang++

Platform codegen flags: -target armv7-none-linux-androideabi

You will need Qt built the same way! My configure command is:

export OPENSSL_LIBS='-L/home/david/QtAndroidBuild/OpenSSL/libs/armeabi-v7a/lib -lssl -lcrypto'
./configure -xplatform android-clang \
    --disable-rpath \
    -nomake tests \
    -nomake examples \
    -android-ndk /home/david/Android/Sdk/ndk-bundle \
    -android-sdk /home/david/Android/Sdk \
    -android-ndk-host linux-x86_64 \
    -android-toolchain-version 4.9 \
    -android-arch armeabi-v7a \
    -android-ndk-platform android-19 \
    -skip qttranslations \
    -skip qtserialport \
    -skip qt3d  \
    -skip qtcharts \
    -skip qtdoc \
    -skip qtmultimedia \
    -openssl-linked \
    -no-warnings-are-errors \
    -opensource \
    -confirm-license  \
    -I /home/david/QtAndroidBuild/OpenSSL/libs/armeabi-v7a/include \
    -prefix /home/david/apps/QtAndroidClang \
    -recheck

You may not need/want OpenSSL so adjust as necessary. I Build 5.10.1.
