#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).
