Re: [eigen] PGI compilation error

[Benoit Jacob <jacob.benoit.1@xxxxxxxxx>]

Sorry, I'm not sure I'm following correctly.

Is the current problem that _mm_malloc is not found?

If yes, then the easy fix is to tell Eigen to not try using it. There
are other solutions for the same need.

Just edit Eigen/src/Core/util/Memory.h, find this:

#ifdef EIGEN_VECTORIZE_SSE
  #define EIGEN_HAS_MM_MALLOC 1
#else
  #define EIGEN_HAS_MM_MALLOC 0
#endif

and replace the '1' by '0' to tell Eigen not to use it.

In the worst case Eigen can always use ei_handmade_aligned_malloc.

Cheers,
Benoit
