Hi!

There seems to be a conflict between GMM and LAPACKE. The following test
program does not compile with g++ 4.8.2 20131010 (prerelease):

#include "lapacke.h"
#include "gmm/gmm_matrix.h"

int main()
{
    return(0);
}

The compiler output is:

********************************************************

/mn/anatu/cma-u3/tmac/usr/stow/gcc/include/c++/4.8.2/complex.h:36:0,

   { add(I, linalg_const_cast(v1)); }
**********************************************************

If I reverse the header file order, it compiles. lapacke.h seems to include
"complex.h", which causes problems with gmm_matrix.h.

Is this a bug in GMM, LAPACKE, or neither?
