Yes, ifx cannot be used at the moment. It is very limited by now and
produces many errors during compilation.
It is a bit worrying, since ifort (2024) gives an info that it will be
disabled next year
Most of the time I tried -O3 it did:
not significantly improve timing (sometimes it
I have rarely seen -O3 help, I only use -O2
You may want to use -xHost, if you have only one type of cpu. Safer.

Hello all,
I tried also to use ifx .. it works for elpa, mpich, fftw and libxc, but
the compilation of WIEN2k has too many errors. With the classic compiler
ifort the compilation works fine and also the workaround for SRC_wplot
does resolve the compilation error.
Elpa recommends flags for

sticking with ifoft.

Dear Peter,
Interestingly, I get the same error when using IFORT with the newest
oneapi...
ifort -O -FR -mp1 -w -prec_div -pc80 -pad -ip -DINTEL_VML -traceback
-assume buffered_io -I/opt/intel/oneapi/mkl/2024.0/include
-DHAVE_PTR_ALLOC_GENERICS -Ilib -free -gen-interface nosource
Dear Peter,
I could compile wien2k 23.2 with no issues using gfortran 13.2.1 (the
version supplied with Fedora 39). I double checked the compile.msg of
SRC_wplot and there are no errors.
Best Wishes

Dear users,
Maybe there is a Fortran expert who knows if this syntax is correct or not.
A user reported recently a compilation problem using the most recent
ifort (or ifx, which will become soon the new fortran compiler)
(oneapi-2024.0) in SRC_wplot:
ifx -O -FR -mp1 -w -prec_div -pc80
