[Pkg-scicomp-devel] Bug#504845: FTBFS with GCC 4.4: missing #include

[James Westby]

Hi,
We have the same issue on Ubuntu as 4.4 is default now. The patch
fixes that error, but it is not enough there.

it is the enums like

  enum {
    DiscretizationType = DiscretizationType::lagrangianFEM0
  };

that are causing this. I'm not sure what the fix would be.

Thanks,
