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

[Yves Renard]

Dear Torquil,

I just tried to include complex.h but it turns out that
#include<complex.h>
and
#include<complex>
are not compatible ! 
It seems that it is not possible to include both. And since gmm includes 
<complex> it seems that this implies that it is incompatible with <complex.h>.

I don't know how you can circumvent this. May be by using some namespaces ...

Yves.

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?
