Hi,

I am trying to use Arrayfire(v3.8.1) in my project.

I am using MKL version 20220000 and I have exactly the same issue described in #3180.

Does this commit really fix the building issue?

The compile works fine if I comments out the version contional at the header inclusion part.

#if INTEL_MKL_VERSION >= 20210004. (here)
#include <mkl_version.h>
#endif (and here)

The header mkl_version.h is the file that defines the macro INTEL_MKL_VERSION. Since the macro is used before the header inclusion, when the conditional is evaluated, INTEL_MKL_VERSION will be 0 (undefined). So, the header will never be included. This means the successing conditionals will be all false, the not-const type for the pointer is still used, and the compile error occurs.

So I think the version checking conditional for the header inclusion should be deleted.

Thank you.

Unfortunately, this fix is broken. There has been another fix recently which actually takes care of this. It will be available in next release.

Thanks.

I can see the solution in the master branch.

@9prady9 @umar456 The 3.8 branch does nt seem to be compat with recent MKL (2021.4 and later) because of these changes of API. Any way to cherry pick that fix into the 3.8 branch ?
