Thanks.
How to reproduce it?

And please just do one think in a commit.
You can use different branches to do different things.

Thanks.

Additional information：

NDK:android-ndk-r10(64-bit)

The Selected NDK toolchain version was 4.8 !

[minggo]

Thanks.

[minggo]

Why your selected toolchain is 4.8?
We have changed to use clang.

[chenguangqi]

I think it's is a bug. see alse method build_native.py in build_native.py
value of NDK_TOOLCHAIN_VERSION is not clang,but 4.7 , 4.8 when NDK is nkd-r10.

Paths of build_native.py:
cocos2d-x/tools/cocos2d-console/plugins/build_native.py
cocos2d-x/templates/cpp-template-default/proj.android/build_native.py

[minggo]

I know the issue. It is because it selects gcc version as previous. But the value will be replaced by the setting in Application.mk. So the final selected compiler is clang.

[minggo]

The output is generated in build_native.py.

User ndk r9d, compiled error whether existed???
