error: string: No such file or directory

Hey all I'm trying to compile Dirty Unicorns Rom for the device GT-I9082 Galaxy Grand Duos...
When i start the building process I get an error as stated below:

target thumb C++: hwuitest <= frameworks/base/libs/hwui/tests/main.cpp
In file included from frameworks/base/libs/hwui/tests/../AnimationContext.h:23:0,
from frameworks/base/libs/hwui/tests/main.cpp:23:

#include <string>

compilation terminated.

make: *** Waiting for unfinished jobs....
Note: Some input files use unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.

For some reason the gcc/g++ compiler is unable to look for the string file in usr/include/c++/4.8
Where it exists I have verified.. Can someone please help resolve this error?

Thanks
