The following error occured after i tried to update from version 7.4 to 7.5:

dev-libs/zenxml 2.3 is installed.
Any Idea what is going wrong here?

[mbucas]

std::make_unique is a C++14 feature.
The gcc command line contains explicit "-std=c++11"

When I change this parameter in the Makefiles to "-std=c++14", using gcc 4.9.3, the build finishes correctly, and FreeFileSync works.

@zenju : Could you update the Makefiles with this option ?

Thanks

Thanks, I've updated the source file accordingly.

Fixed. Thank you very much!
