[iamsergio]

Which compiler is that ?

[mrueg]

I'm using gcc-4.9.3 and cmake-3.6.2

[iamsergio]

Are you building through emerge/portage or directly using cmake ?

[mrueg]

I'm building it via emerge. Can try to build it directly later.

[mrueg]

it fails via direct cmake as well

[iamsergio]

Can you try adding -std=c++11 to CXXFLAGS ?

[iamsergio]

Fixed in 1.1 branch, can you test before I tag it ?

[mrueg]

@iamsergio Yes that patch fixes it. Thanks!
