#2553: Cactus' link command uses CPPFLAGS and CXXFLAGS

 Reporter: Roland Haas
   Status: open
Milestone: 
  Version: development version
     Type: bug
 Priority: minor
Component: Cactus

Comment (by Erik Schnetter):

You would need to point Spack to the compiler and MPI libraries that it should use \(and maybe a few more\), and then build the rest. Building your own MPI library is easy; using it is next to impossible since it’s very difficult to configure it to use the existing hardware \(and it’s probably actually impossible on Crays\).
