Meep doesn't build

[martinkielhorneffect]

When trying to build meep I get this error: bend-flux-ll.o: In function create_structure_by_hand(bool, bool, meep::volume&, meep::volume&, meep::volume&)': bend-flux-ll.cpp:(.text+0x120a): undefined reference tomake_prism' bend-flux-ll.cpp:(.text+0x136d): undefined reference to `make_prism'

I tracked this down to this change: https://github.com/stevengj/libctl/pull/13

I fixed this by downcasing two types in line 2423 in utils/geom.c: geometric_object make_prism(material_type material,

You need to have the latest version of libctl to build the latest Meep.

Not sure what you mean by "downcasing".

[martinkielhorneffect]

By downcasing I mean that I convert this line: GEOMETRIC_OBJECT make_prism(MATERIAL_TYPE material, into that line: geometric_object make_prism(material_type material, in https://github.com/stevengj/libctl/blob/master/utils/geom.c

[stevengj]

GEOMETRIC_OBJECT is already #defined to geometric_object in ctlgeom.h, so I'm not sure what is going on here...

[stevengj]

Oh, I think maybe the problem is that geom.c does #include <ctlgeom.h> instead of #include "ctlgeom.h", and maybe it is using an old version of ctlgeom.h on your machine instead of the one in the same directory?

That being said, there is no reason to use the uppercase versions in this file, so I will change that too.
