cross compile Qt5 source on DM8168/AM389x
-
@ambershark @Alex_wang Qt itself requires C++11 since (I think) 5.6, so without C++11 5.9.1 will for sure not build.
@jsulm @ambershark
Can you tell me where to configure the "-std=gnu++11" ,change it to "-std=c++11"?I can't find the configure file.

@Alex_wang Does "configure --help" show anything?

You will need a more modern compiler to use Qt newer than 5.6.

Actually, Qt 5.6 was the last Qt version that didn't need a C++11 compiler [1][2]. Version 5.7 was the first one with that requirement.
[1] Except if you want to use QtSerialBus, which is a Technology Preview in Qt 5.6 and already required C++11.
[2] And it is the last version supporting Windows XP. -
