Re: [Getfem-users] Conflict between GMM and LAPACKE

[Torquil Macdonald Sørensen]

complex.h causes similar problems with boost, as reported here:

https://svn.boost.org/trac/boost/ticket/8349

As you can see, that report is classified as "wontfix", and I think GMM 
should not be fixed either.

So LAPACKE seems to conflict with several pieces of software due to 
this, unless it is possible to stop it from including complex.h. I'm 
waiting for them to get back to me on their forum.

My solution for now is as proposed in the boost report above:

#include "lapacke.h"
#undef I
#include "gmm/gmm.h"

which seems to work fine.

Best regards
