#2933: CarpetX's reduction.hxx is not self-contained

Reporter: Roland Haas Status: new Milestone: Version: Type: bug Priority: major Component: CarpetX

Changes (by Roland Haas): using just `USES INCLUDE HEADER reduction.hxx` in interface.ccl and then:

``` #include "reduction.hxx"

```

I get an error message:

``` /home/rhaas/postdoc/gr/cactus/ET_trunk/arrangements/CarpetX/CarpetX/src/reduction.hxx:24:22: error: ‘amrex’ does not name a type [-Wtemplate-body] 24 | using tuple_type = amrex::GpuTuple<T, T, T, T, T, T, T, T>; ```

making amrex available (by including `loop_device.hxx` first, which seems wrong) I then get:

``` In file included from /home/rhaas/postdoc/gr/cactus/ET_trunk/configs/sim/bindings/include/reduction.hxx:4, from /home/rhaas/postdoc/gr/cactus/ET_trunk/configs/sim/build/CenterOfMass/centerofmass.cc:6: /home/rhaas/postdoc/gr/cactus/ET_trunk/arrangements/CarpetX/CarpetX/src/reduction.hxx:123:30: error: ‘dim’ was not declared in this scope; did you mean ‘Loop::dim’? 123 | typedef reduction<CCTK_REAL, dim> reduction_CCTK_REAL; | ^~~ | Loop::dim ```

which also seem wrong.
