fatal error: mkl.h: No such file or directory

[Maraki]

Hello,

I have installed intel One base toolkit on windows and I am trying to compile  a c code in R desktop. I am facing the following issue:

> system("R CMD SHLIB example.c") 
using C compiler: 'gcc.exe (GCC) 12.2.0'
gcc  -I"C:/PROGRA~1/R/R-43~1.1/include" -DNDEBUG     -I"c:/rtools43/x86_64-w64-mingw32.static.posix/include"     -O2 -Wall  -mfpmath=sse -msse2 -mstackrealign  -c example.c -o example.o
example.c:3:10: fatal error: mkl.h: No such file or directory
    3 | #include <mkl.h>
      |          ^~~~~~~
compilation terminated.
make: *** [C:/PROGRA~1/R/R-43~1.1/etc/x64/Makeconf:265: example.o] Error 1

I've read here instructions on utilizing R with Intel MKL, but those specific instructions are designed for Linux, and I don't have the expertise to modify the process as I'm not well-versed in Linux. 

I have tried also the following but  with no luck

> system("R CMD SHLIB -I 'C:/Program Files (x86)/Intel/oneAPI/mkl/latest/include' example.c")
using C compiler: 'gcc.exe (GCC) 12.2.0'
make: *** No rule to make target 'Files'.  Stop.

Thank you very much

Hi,

Thanks for posting in Intel Communities.

Could you please let us know the Intel MKL version you are using?

Also, could you please provide us with the complete steps you are following on the R desktop along with the sample reproducer code you are using?

Thanks & Regards,

Hi,

>>example.c:3:10: fatal error: mkl.h: No such file or directory

  3 | #include <mkl.h>

   |     ^~~~~~~

From this error, we can see that Intel MKL does not link properly. Also, from the compiler options provided by you, we did not see the option '-qmkl' so this might be causing an error.

Could you please try adding the flag and let us know if you still have any other issues?

Thanks & Regards,
