[QE-users] [[QE-GPU]Can't find include file fftw3.f03(QE-7.0-rc1)

[kuangll]

Hi experts,

I try to compile the QE - GPU version, with version qe-7.0-rc1. 

I use HPC SDK 21.9, and after successfully configuring, I modify the DFLAGS in make.inc and use -D__FFTW3 instead of -D__FFTW. 
Then error accur when compiling progress to this step: 


mpif90 -fast -Mcache_align -Mpreprocess -Mlarge_arrays -mp -D__CUDA -D__USE_CUSOLVER -D__FFTW3 -D__MPI -cuda -gpu=cc80,cuda11.4 -I/qe/q-e-qe-7.0-rc1//external/devxlib/src -I/qe/q-e-qe-7.0-rc1//external/devxlib/include -acc -I/qe/q-e-qe-7.0-rc1//external/devxlib/src -I/qe/q-e-qe-7.0-rc1//include -I/qe/q-e-qe-7.0-rc1//FoX/finclude -c la_types.f90

I check there's no file fftw3.f09 in LAXlib directory.  Where can I get this file? 

Thanks.
