Intel compiler uses gcc immintrin.h header instead of its own one

[Marco]

I'm using the intel compiler 19.0.3.199 on ubuntu 18.04 and I have a problem when I include the file immintrin.h.

The error is:

In file included from /usr/lib/gcc/x86_64-linux-gnu/7/include/immintrin.h(41),
                 from ../lib/io/exchange_format.c(38):

The compiler seems to use the header file of gcc instead of the one in the directory /opt/intel/compilers_and_libraries_2019/linux/include/icc.

If I add the option -I/opt/intel/compilers_and_libraries_2019/linux/include/icc to the makefile rule I can compile this object.

I'd like to understand why icc doesn't look into its own include directories but it looks into the gcc ones.

P.S. I launched the script compilervars.sh before compiling.

Not so sure what happened at your end, but it should have used the headers from icc.

Will you be able to give us a test case?

I am facing the same problem with Intel Parallel Studio XE 2022 Update 1 Cluster Edition (oneAPI) on Red Hat Enterprise Linux release 8.5 (Ootpa). Nothing changes even if I explicitly include the intel files.

Please help!

Can you provide us a test case and your actual error?

Thanks,
