Help running HElib in windows with Mingw compiler

[shrram12]

I am new to FHE and I would really appreciate if you can help me with the errors I am noticing when building HElib.

Environment : Windows 10
Compiler : MinGW 6.3.0
GMP: 6.1.2
NTL : 11.3.0

Makefile :
CFLAGS = -g -O2 -std=c++11 -pthread -DFHE_THREADS -DFHE_BOOT_THREADS -fmax-errors=2 -I C:/Users/sr/Downloads/WinNTL-11_3_0/WinNTL-11_3_0/include -L C:/Users/sr/Downloads/WinNTL-11_3_0/WinNTL-11_3_0/src/Debug -l NTL_static_lib -I C:/MinGW/msys/1.0/include -L C:/MinGW/msys/1.0/lib -l libgmp

Error :
C:\git\HElib\src>make
HElib requires NTL version 10.0.0 or higher, see http://shoup.net/ntl
If you get compilation errors, try to add/remove -std=c++11 in Makefile

g++ -g -O2 -std=c++11 -pthread -DFHE_THREADS -DFHE_BOOT_THREADS -fmax-errors=2 -I C:/Users/sr/Downloads/WinNTL-11_3_0/WinNTL-11_3_0/include -L C:/Users/sr/Downloads/WinNTL-11_3_0/WinNTL-11_3_0/src/Debug -l NTL_static_lib -I C:/MinGW/msys/1.0/include -L C:/MinGW/msys/1.0/lib -l libgmp -c NumbTh.cpp
