Error during make

I have fftw 3.3.5 and gcc version is 6.2.0 on ubuntu 16.10 64 bit machine. I am getting the following error while trying to run the makefile. $make

g++ -Wall -O3 -c FFT.cpp In file included from FFT.h:4:0, from FFT.cpp:3: params.h:26:31: warning: result of ‘(536870913 << 11)’ requires 42 bits to represent, but ‘int’ only has 32 bits [-Wshift-overflow=] const ZmodQ vgprime[3] = {v, v<<11, v<<22}; ~^~~~ params.h:26:38: warning: result of ‘(536870913 << 22)’ requires 53 bits to represent, but ‘int’ only has 32 bits [-Wshift-overflow=] const ZmodQ vgprime[3] = {v, v<<11, v<<22}; ~^~~~ FFT.cpp: In function ‘void FFTforward(double ()[2], const ZmodQ)’: FFT.cpp:24:15: error: expected primary-expression before ‘double’ res[k] = (double complex) out[2k+1]; ^~ FFT.cpp:24:15: error: expected ‘)’ before ‘double’ FFT.cpp: In function ‘void FFTbackward(ZmodQ, const double ()[2])’: FFT.cpp:29:19: error: expected primary-expression before ‘double’ out[2k+1] = (double complex) val[k]/N; ^~ FFT.cpp:29:19: error: expected ‘)’ before ‘double’ FFT.cpp:30:19: error: expected primary-expression before ‘double’ out[2*k] = (double complex) 0; ^~ FFT.cpp:30:19: error: expected ‘)’ before ‘double’ Makefile:30: recipe for target 'FFT.o' failed make: *** [FFT.o] Error 1

I think PR #9 can fix this error.
