[Pw_forum] FFTW in PWscf?

[Dai]

i guess you're using the internal copy of fftw, plz check the make.sys file after you did the configure. if you have -D__FFTW -D__USE_INTERNAL_FFTW, that means the the internal copy of FFTW is compiled during your installation.

主题： [Pw_forum] FFTW in PWscf? 
 
Dear PWscf Users,
When I compile PWscf by a simple ./configure, then I get:

The following libraries have been found:
BLAS_LIBS= -lmkl_ia32
LAPACK_LIBS= -lmkl_ia32
FFT_LIBS=
Please check if this is what you expect.

It seems to be not detected FFT_Lib?
Then I make all, I get binaries with them I tested examples and the results are in good agreement with output in refference but I don't know FFTW is still missing in the binaries or using a FFTW version of the PWscf code instead?
How to correct this?

Best Regards,
