In a terminal:


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:

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:


So instead of entering


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

Dear Professor Peter,

Thank you for the clarification, I did let it as default, I did not change it and still the same error occur.

sgroup is a C-program. Thus it has nothing to do with the
ifort-conmpiler options, but with your C-compiler.

Did you use icc or just cc ?? It is probably best to leave it as set in
the default.
