The problem might be with the FFTW-LIBS. In the steps at [1], it looks
like it set to "lib", but it is set to "lib64" in your case.
Check if libfftw3_mpi.a exists in lib or lib64.
For example, if the file exists in lib:
username@computername:~$ ls /home/username/fftw3/lib
cmake libfftw3.a libfftw3.la libfftw3_mpi.a libfftw3_mpi.la pkgconfig
Then, adjust your settings accordingly:
username@computername:~$ cd $WIENROOT
username@computername:~/WIEN2k$ ./siteconfig
...
Selection: O
...
F FFTW options: -DFFTW3 -I/home/username/fftw3/include
FFTW-LIBS: -L/home/username/fftw3/lib64 -lfftw3
FFTW-PLIBS: NOT FOUND!
...
Selection: F
...
Selection:L
Enter the target achitecture of your FFTW library (e.g. lib64)!: lib
...
FFTW_OPT: -DFFTW3 -I/home/username/fftw3/include
FFTW_LIBS: -L/home/username/fftw3/lib -lfftw3
FFTW-PLIBS: -lfftw3_mpi
...

Hellow wien2k users,
I am facing a problem in compiling FFTW in sitecofiguration. I have
followed all the steps as in
"https://www.mail-archive.com/wien@zeus.theochem.tuwien.ac.at/msg18664.html";.
But could nopt acces the
"/home/username/fftw3/mpi/.libs/libfftw3_mpi.a" as in in mailing list.
the current settings for FFTW is
F FFTW options: -DFFTW3 -I/home/edison1/fftw3/include
FFTW-LIBS: -L/home/edison1/fftw3/lib64 -lfftw3
FFTW-PLIBS: NOT FOUND!
How can I solve this issue?
Regards,
Riyajul Islam
