note on relative header paths

[Stephane Popinet]

Dear all,

I see quite a few codes in sandboxes using relative paths to header
files i.e. codes looking like:

#include "../../popinet/distance_point_ellipse.h"
#include "../alex_functions.h"
#include "../LS_reinit.h"
#include "../basic_geom.h"

This is clearly much better than copying these files locally (as also
seen in some sandboxes), but not as good as:

#include "popinet/distance_point_ellipse.h"
#include "alimare/alex_functions.h"
#include "alimare/LS_reinit.h"
#include "alimare/basic_geom.h"

which works because the default sandbox Makefile includes the line
-I$(DOCUMENT_ROOT)/sandbox, see:

http://basilisk.fr/sandbox/Makefile
