compiling error

[yjx1217]

Hello,

I was trying to compile mgra on my system following the instruction. I passed the "cmake" step but got error in the "make" step. Please see the following error message for your reference. The version I used was directly obtained from github by git clone. Thanks in advance!

Thanks for your feedback and sorry for delay!

GCC 4.4 is too old (you need at least 4.6 for new C++ standard support). We strongly recommend to use GCC 4.8 version. The easiest thing you can do is to use our web-server - http://mgra.cblab.org/

And again sorry for delay.

Hi Avdeev,
I've updated my GCC to 4.8 but it seems the problem still exists.
