What compiler/version are you using?

ericniebler commented 8 years ago

Hello?

soulslicer commented 8 years ago

cmake version 3.2.2

g++ (Ubuntu 4.8.4-2ubuntu1~14.04.1) 4.8.4

g++ (Ubuntu 4.8.4-2ubuntu1~14.04.1) 4.8.4

@soulslicer Meta requires a "pretty much conforming" C++11 compiler, which for gcc means g++ >= 4.9.

For some reason this is not in the readme.

gnzlbg commented 8 years ago

I quickly added the info that gcc >= 4.9 and clang >= 3.4 are supported to the readme since those are the compilers we actively try to support.

I wouldn't be surprised if some of them don't work though. I recall some issues with clang 3.5, and GCC 5.x + C++14 + constexpr never quite worked properly.
