Hi! I have been trying to add CLang support for my android v-play project. I did a clone of the “Android for x86 (GCC 4.9, Qt 5.11.1 Android x86 Felgo)” and change the c++ compiler to an android toolchain I created before using the android ndk. The Clang version is 6.0.2. But I got an error when compiling:

I guess the VPlay library is not compatible because it has been built with GCC. Do you expect to have CLang support for android soon?

Hi Jimmy,

Felgo builds upon Qt, which currently supports compiling Apps for Android using GCC.
You can have a look the supported Qt platforms here: http://doc.qt.io/qt-5/supported-platforms.html

Qt will support CLANG with the upcoming version Qt 5.12, as GCC is already deprecated. For the moment, this means that all Qt modules require a custom compilation for clang before you can build a Qt app with clang. (the same applies for the Felgo library).

We always support the currently stable Qt version, so we recommend to stay with GCC until Qt officially steps up.

Best,
Günther

Günther,

Given we compile the latest qt-5-12-alpha with clang:

Can we get a clang compiled v-play from you?

Thanks!

Hi Hiro,

we can provide a Felgo Library build for clang with the included support of Felgo Enterprise, or with the purchase of a support package. If that’s interesting for you, please drop us a line at support@felgo.com to follow up with the details.

Best,
Günther

Thanks Gunther. This is a pretty big problem since the android ndk-17 has deprecated gcc and gnustl, and ndk-18 removed them completely.
It’s not going to be possible to do Android applications with gcc for very much longer.

It really shouldn’t require us to pay extra for v-play to keep the software up to date with the official ndks for their supported platforms.

That being said after we know this all works with modern c++11 we will be getting licenses for all our QML devs. Thanks.
