SDK 3.13.5 fails on qfutureinterface.h

Platform Development

After the update to the stable SDK

SDK_RELEASE=3.13.5
SDK_RELEASE_CYCLE=Stable
SDK_CONFIG_DIR=SailfishSDK
SDK_VENDOR="Jolla"

I fail to compile the project which uses QtConcurrent with the following output:

… 22 issues in total, in qfutureinterface.h and qtconcurrentthreadengine.h. It looks like it is enough to simply

#include <QtConcurrent/QtConcurrent>

for the build to fail, and the same applies to the i486 target

I wasn’t able to find ‘Known issues’ in the release announcement, and I’m far from an advanced level of C++ or Qt, but this doesn’t look like something that was caused by the application code.

Any help (even in the form “act as an adult and use real threads“) is appreciated.

I think you are the third to report, after

and @Mister_Magister on irc.

Much newer C++ version (20) that Qt 5.6 was ever meant for, and now a newer compiler that supports more of it.
