cross compile Qt5 source on DM8168/AM389x

This is your problem
cc1plus: error: unrecognized command line option "-std=gnu++11". The-std=gnu++11is not valid in your compiler. Which makes sense. Most ARM compilers are not very up to date. If you need c++11 support try changing gnu++11 to c++11 and that should fix your issue.This assumes that your compiler supports c++11, which it may not at all, in which case you have to remove c++11 support.
Edit: Oops I should read more.. this is compiling Qt source not your own project. You will need to disable c++11 support in Qt if your ARM compiler doesn't support it. I'm not sure if that's even possible now-a-days, but a quick
./configure --helpshould give you the answer. -
@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.

@Alex_wang Does "configure --help" show anything?
-
@Alex_wang Here's from
./configure --help:-c++std <edition> .... Select C++ standard <edition> [c++1z/c++14/c++11] -

@Alex_wang What is your target architecture and its CPU?

@Alex_wang Looks like your compiler doesn't support c++11 or higher. 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. -

Looks quite old. Can you get a newer one?

Thanks for your reply!
using the gcc-linaro-6.3.1-2017.05-i686_arm-linux-gnueabi tool chain , then solve the error!
but new error occur:

@Alex_wang Did you start from a clean state?
-
@Alex_wang Does your new compiler support exceptions and have exception handling enabled?
