compile error: missing binary operator before token "("

[vvovvo]

I got missing binary operator before token "(" when running make. cmake successfully completed but it stuck at the make step. Any suggestion will be appreciated.

It is on a Ubuntu 14.04, GNU Make 3.18, cmake version 3.11.0-rc3.
Details of the error:

You're going to need GCC 5. Install it or upgrade to Ubuntu 16.04.

Perhaps easier, you could also remove the __has_include directives around those header files, since they exist on your platform.

I changed the code and checked that it builds with GCC 4.8 on Ubuntu 14.04. I'd still recommend getting an up-to-date compiler if you're going to build things from source. Hope that helps.

[vvovvo]

That's greatly helpful! Much thanks.

Thank you very much. Using an up-to-date compiler worked.
