[Wien] ifort classic compiler now discontinued in one-api 2025.0 online repositories

[Michael Fechtelkord]

I have compiled the FFTW Libraries using "--enable-openmp switch" 
(complete commandline below):


FC=ifx F77=ifx CC=gcc CFLAGS="-O3 -march=native -mavx2" FCFLAGS="-O3 
-xAVX2"\
   ./configure --prefix=/usr/local/ --enable-shared --enable-mpi 
--enable-openmp --enable-threads --enable-avx --enable-avx2

It should produce both: an ‘fftw3_omp’ and an ‘fftw3_threads’ library .. 
I have also checked up "/usr/local/lib64" were both libraries exist.

Best regards,

Michael
