[GRASSLIST:2290] example plot_raster_map aus progmangrass (p.264)

GRASS GRASS user

Hi there,

I tried to implement the example plot_raster_map aus progmangrass (p.264) to get used to the C-programming in GRASS.
I use a source code installation of grass 5.0.3 on a linux Suse 8.2

After several iteration of the Gmakefile and the plot_raster_map I allways get a hell of an error stack which starts with:

  ./bin/gmake5

the Gmakefile like this:

did forget to include a module?
can anybody tell me how to go on?

Thanxs for any advice Dani isenegger

ps the status after the installation was;

You need to add $(MATHLIB) to this line.

To be on the safe side, use of $(GISLIB) should always be followed by:

  $(DATETIMELIB) $(XDRLIB) $(MATHLIB)

as various parts of it may depend upon one or more of those libraries.

Just for info:

this thing was just an ordering problem:
LIBES= $(DISPLAYLIB) $(RASTERLIB) $(GISLIB): works

instead of
LIBES= $(GISLIB) $(DISPLAYLIB) $(RASTERLIB): does not work

why this is so important, I don't know yet ....

cheers

Hi Glynn,
thanks for you advice. I included it in the Gmakefile:

HOME=$(BIN_CMD)
# include of dirs, e.g.gis.h is in ...
EXTRA_CFLAGS= -I /data/gis/nfp48/nfp48/ipodlas0.1/grass/grass5sources/grass-5.0.3/src/include
# including of libs: e.g. D_ are in DISPLAYLIB
LIBES= $(GISLIB) $(DATETIMELIB) $(XDRLIB) $(MATHLIB) $(RASTERLIB) $(DISPLAYLIB) $(IMAGERYLIB) $(VASKLIB) $(VASK)
DEPLIBES= $(DEPIMAGERYLIB) $(DEPGISLIB) $(DEPVASKLIB) $(DEPVASK)

OBJ = ctest.o plotRasterMap.o
ctest: $(OBJ) $(LIBES) $(DEPLIBS)
    $(CC) $(LDFLAGS) -o $@ $(OBJ) $(LIBES) $(DEPLIBES)

$(LIST): global.h
$(LIBES): #in case of library change;i.e.they must be here, if in rules
$(DEPLIBS):

and actually a different error:
/data/gis/nfp48/nfp48/ipodlas0.1/grass
  make -f OBJ.i686-pc-linux-gnu/make.rules

/data/gis/nfp48/nfp48/ipodlas0.1/grass/grass5sources/grass-5.0.3/src/libes/display/raster.c:171: undefined reference to `R_move_abs'/

i have to check that: if I get any further from here

thanks dani
