This seems to be because the names :FFTW_LIB and :FFTW_LIBNAME are too
similar on lines 157 and 158 in siteconfig_lapw.
So when you "grep :FFTW_LIB WIEN2k_OPTIONS", it gives lib and fftw3 from
both of them:
username@computername:~/WIEN2k$ grep :FFTW_LIB WIEN2k_OPTIONS | cut -d :
-f 3-
lib
fftw3
Adding a colon after the :FFTW_LIB looks like it might fix that:
username@computername:~/WIEN2k$ grep :FFTW_LIB: WIEN2k_OPTIONS | cut -d
: -f 3-
lib
So try changing line 157 in siteconfig_lapw from:
username@computername:~/WIEN2k$ sed -n 157p siteconfig_lapw
set FFTW_LIB = `grep :FFTW_LIB $bin/WIEN2k_OPTIONS | cut -d : -f 3-`
to
set FFTW_LIB = `grep :FFTW_LIB: $bin/WIEN2k_OPTIONS | cut -d : -f 3-`

I am attempting to compile Wien2k_17 on an amd linux machine with actual cores
that include fpu's, and running ubuntu 16.04. I have compiled fftw3 and
installed it in /usr/local/fftw_3.3.7/lib. I am setting the fftw parameters for
compilation. I start with the following:
FFTWROOT: /usr/local/fftw_3.3.7/
FFTW_VERSION: FFTW3
FFTW_LIB: lib
FFTW_LIBNAME: fftw3
so that
FFTW_LIBS: -L/usr/local/fftw_3.3.7/lib -lfftw3
The problem arises when I save these settings, two menus above. When I then
return to the parallel options, I find that FFTW_LIB: has changed to
FFTW-LIBS: -L/usr/local/fftw_3.3.7/lib fftw3 -lfftw3
Note that an additional fftw3 intervenes between the directory name and the
-lfftw3. In fact, each time I save and return, another copy of fftw3 appears.
This renders compilation of fftw3 impossible. I have had a slightly more than
casual look at the siteconfig_lapw script, and I can't see where this is
happening.
As I am completely stymied at this point, any help would be greatly appreciated.
