'locate ogr_api.h' gives:
/usr/include/gdal/ogr_api.h
The relevant lines in include/grass/vect/dig_structs.h are
#ifdef HAVE_OGR
#include "ogr_api.h"
#endif
When I change this to
#include "gdal/ogr_api.h"
it compiles correctly.
Strange. Does ogr_api.h use the "gdal/" prefix in headers which it
includes?
No
What does "gdal-config --cflags" say?
$ gdal-config --cflags
-I/usr/include/gdal
Is this a bug in grass,
I think that it's a bug in i.pr.
i.e. should this be gdal/ogr_api.h in the headers file ?
No; "gdal" is not part of the header name, at least not in the version
I have (1.3.1). Headers don't use that to refer to themselves.
Modules which include vector headers need to have:
EXTRA_CFLAGS = $(VECT_CFLAGS)
in their Makefile. i.pr would appear to have omitted this.
Yes, that was it. Thanks.
