[Pw_forum] Cannot allocate FFT

[GAO Zhe]

Dear QE users and developers,


I am trying to compile QE 5.4.0 under MinGW-32 with MPICH2.
However, pw.x met error while allocating FFT as following:
     G-vector sticks info
     --------------------
     sticks:   dense  smooth     PW     G-vecs:    dense   smooth      PW
     Sum           0       0      0                    0        0       0
 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
     Error in routine allocate_fft (1):
     wrong ngm
 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
 
During compiling, the only warning information was occurred for zhpev_drv.f90 in LAXlib as:


gfortran -O3 -static  -x f95-cpp-input  -D__WIN32 -D__FFTW3 -D__GFORTRAN -D__STD_F95 -D__MPI -D__PARA   -I../include -I/$(MPICH_TOP)/include -I/local/include  -I../ELPA/src   -c zhpev_drv.f90

       SAVE /MPIFCMB7/, /MPIFCMB8/
           1

So far, I have no idea why the strange error took place. Would you like to share some comments with me how to avoiding the error?
Many thanks.
Best Regards,
