[Wien] OS and processor instruction error

[Gavin Abo]

In a terminal:

cd $WIENROOT
./siteconfig
C
ifort
cc
enter
R
A

The default C compiler in the fifth step above should be cc (or gcc).  
Did you enter cc (or gcc) for the compiler and then recompile (A in the 
eighth step to compile all programs)?

If you are trying to use icc instead of cc, then you might need to check 
what your system processors are and specify the processor-specific 
options for it.  For example, if you are using the Intel C++ (icc) 
Compiler 16.0, the User and Reference Guide for it on the Intel website 
should be at:

https://software.intel.com/en-us/node/581749

In addition to documentation on the Intel website, you can also likely 
find the documentation for your specific icc version in folders at the 
location where you installed the Intel compiler on your system, which is 
usually something like:

/opt/intel/composerxe/Documentation/

So instead of entering

icc

you could try one of the options that should target a processor without 
the AVX2, so you could try entering for example:

icc -xSSE4.2
