Yes, but what I meant is that I don't see where the proj_wrap_c_FLAGS
variable is read.

So it seems that the gdal includes directory is not taken into account.

In include/Make/Platform.make I see:

GDALCFLAGS          = -I/usr/include/gdal
[...]
PROJINC             =  $(GDALCFLAGS)

so at least /usr/include/gdal should be in the gcc line, I guess.
