GCC minimum version required about uvw HOT 4 CLOSED

Damn, that's true. And the autoconf macro that checks for -std=gnu++14 tells that gcc4.9 can do C++14...
That's bad.

We can use try_compile to test the compiler while running cmake, so that the compilation process is stopped in the early stages. Anyway it sounds like we need to test more or less all the available features from C++14, it isn't that easy to do that.
Moreover, I don't get the error. It has the same type for the data member and for the parameter. Why stat is seen as a long unsigned int? It doesn't make much sense.
Am I missing something?

I have no idea why stat is long unsigned int... But because it's gcc 4.9.2 it is most likely a compiler bug here.

Of course with a newer GCC (5.3) I don't get any error.

from uvw.

I see. What I mean is that I wouldn't even know what's the feature to be tested to catch this kind of errors.
Anyway, according with C++ standard support in GCC, I'd definitely say that 4.9 doesn't support C++14.
Therefore, saying that one must use a C++14 fully compliant compiler sounds still good.
