Soumendu,

Can you try adding "-std=c11" to the gcc flags and see if that makes the cast warning go away? I can't reproduce the warning on my end.

The math.h error looks like an environment issue. I don't offhand see anything in the code that would specify using the Intel math.h. Also, did you clear out all the object files before you compiled and got this error?

Adding "-std=c11" fixed the aligned_alloc() cast warnings. Intel error was a local environment issue.
