[Wien] Compiling problem with wien2k_06

[Gerhard H Fecher]

That is not a bug of the compiler, it seems that the Linux Linker (that is not 
part of the Fortran compiler) on some Linux systems  does not understand what 
ifort is telling depending on the version.

The easiest way is to put -no-ipo (please check the syntax probably its not 
correct, but I don't have it at hand) in the Linker options (not the Compiler 
options)
Another way is to use the switch -O0  for the Linker (not Compiler !!!!) 
options, what means the Linker should not try to optimize, what it does not 
do anyway.
Both prevent that the Linker thinks  it has to do inter-procedural 
optimizations between different files. You still can tell the Compiler it may 
do interprocederal optimizations for a single file (-ip,  (!) not   -ipo that 
concerns different object files), as this is his duty and not the one of the 
Linker.

On the web you may also find some funny ways to create the empty files that 
the Linker is missing for whatever reason.

Ciao
Gerhard
