can't compile bmdc on ubuntu 12.04

In /SConstruct file change line #317 env.Append(CXXFLAGS = '-std=c++11') to env.Append(CXXFLAGS = '-std=c++0x') then *should fine compile but not sure.... is mainly because Ubuntu 12.04 had bit old gcc......

Thank you, that helped at that point.
Now there's another error:

as i said Ubuntu 12.04 have old tool chain ( and DC++ core officialy support only 4.8+) , i think Ubuntu 12.04 had 4.6 with incomplete c++11 support that reason is.

if know some about C/C++ you can change that lines to somethink like with insert , but do not recomdment that way.

and also last LTS of Ubuntu is 14.04, so i advise update system , then you can also install via ppa i think

Thanks, i will try to update to Ubuntu 14.04 when i have free time.
