I am using minGW as the compiler and our code has a lot of FFT. In the past we use fftw and we want to try Intel's fft to improve it.
I download the trial version of the MKL and install it on my computer (64 bit Windows 8). I also download the first sample code from the website. (https://software.intel.com/sites/products/documentation/hpc/mkl/mklman/G...)
However, I don't know how to compile it in minGW. In the pass, we just input in the windows command window: gfortran -o test.exe -O2 testfortran.f -LC:\\Windows\system -lfftw3-3. This can link our code to the fftw's fft library. But I don't know how to link the code to the new library in minGW compiler.
Could some please tell me where I've made a mistake? We appreciate your help.
We just want to do the forward and backward fft. If there is an easy example of Fortran code just tells us how to use the Intel's forward fft and backward fft, it would be very helpful.
