catastrophic error: cannot open source file "mkl.h"

Hi,

I really really really have a hard time navigating this site. So sorry if the docs state it.

I'm trying to run the matrix multiplication example found at https://software.intel.com/content/www/us/en/develop/download/609945.html

I then installed Intel MKL and the Intel Parallel Studio XE. The only reason I installed the Studio was the icc compiler. I don't plan to use any IDE currently.

So I installed

https://www.archlinux.org/packages/community/x86_64/intel-mkl/

https://aur.archlinux.org/pkgbase/intel-parallel-studio-xe/

Now if I cd into the directory for the example and use make I get:

$ make
icc -c src/dgemm_example.c -o release/dgemm_example.o
src/dgemm_example.c(27): catastrophic error: cannot open source file "mkl.h"
#include "mkl.h"
^

compilation aborted for src/dgemm_example.c (code 4)
make: *** [Makefile:26: release/dgemm_example.o] Error 4

I guess that's because there are no environment variables set. I tried to figure out how but e.g. the getting started guide for 2020 only points me to that "compilation command generator" tool. Which I don't need since i have a makefile.

So if I'm right with my assumption that I need to set env vars, which one do I need to set?

Also is it possible to use icc without all the IDE stuff? Or whatever is included in that Parallel Studio?

Thanks

>> Please set the mkl environments to your session by calling mklvars.sh script.

e.x: source /opt/intel/compilers_and_libraries_2020/linux/mkl/bin/mklvars.sh intel64

>> then dotn’t forget to add the mkl Include file directory when you compile your test:

icc -c -IMKLROOT/Include dgemm_example.c -o release/dgemm_example.o

....

>> You may also try to check how to builf the examples ( mklroot/examples folder) where you may find out makefiles which help to build these examples with many of supported mkl's modes

>> and please check MKL Getting Started documentation to see all needed info
