[Trilinos-Users] Trilinos and umfpack - build with intel compilers

[Martin Vymazal]

Hi Eric and Ross,

  in fact, I was trying to download and compile some packages (like  
AMD, for example) needed by umfpack separately. When this didn't work,  
I downloaded the whole suitesparse pack and recompiled everything from  
scratch. This time, compilation of trilinos went fine (even though the  
version of umfpack should be the same). I don't understand where was  
the problem, but I'll simply stick with whatever works. Thank you for  
your replies.

  Best regards,

    Martin Vymazal
