[Wien] FFTW error in CRAY compilation

[Francisco Garcia]

*Dear Users,*


*I keep getting the following error in the CRAY compilation of WIEN2k (this
occurs in routines which require FFTW such as lapw0, lapw1, etc.):*



*Error:*

*Version FFTW3 of fftw is not compatible with craype/2.x.*

*If fftw/FFTW3 is not required:*

*'module swap fftw fftw/3.3.0.4 <http://3.3.0.4/> (or newer)'.*




*I find the error surprising because I am using the latest version of FFTW3
(version 3.3.10.6). *


*Any suggestions on how to fix this problem would be appreciated.*




*Below are my important compilation details.*



*module swap PrgEnv-cray/8.5.0 PrgEnv-intel/8.5.0*


*module load cray-mpich/8.1.28*

*module load intel-oneapi/2023.2.0*

*module load intel-mkl/2023.2.0*

*module load cray-fftw/3.3.10.6 <http://3.3.10.6>*


*Fortran MPI compiler: ftn*


*C compiler: cc*


*FFTW3 version: 3.3.10.6*
