Re: [GRASS-dev] Difficulty compiling GRASS on Mac

[Michael Barton]

Eric Hutton at the Community Surface Dynamics Modeling System has created a 
recipe for compiling GRASS using Anaconda. You can find it at: 

https://github.com/csdms-stack/grass-recipe

I'm using a variant of this to create the stand-alone binaries for the Mac.

I think you need to call M_read_list() first, before you loop over the
tiles.

 Hi,

 it would be very useful to have a quiet option for r.in.bin used in
 write() method of objects in grass.script.array.

 Yes, it is only logging percents, but due to this behaviour, it cannot be
 used in a loop with its own percentage log (it will contain a 100 % log
 for each loop).

thanks, now it compile but I get "Segmentation fault", the module is
r.tile, I attached the diff, could someone have a look to it please?

this is a problem of the linker: you need to link against the manage lib,
see e.g. the Makefile for g.remove. Try

LIBES = $(MANAGELIB) $(RASTERLIB) $(GISLIB)
DEPENDENCIES = $(MANAGEDEP) $(RASTERDEP) $(GISDEP)

in the Makefile of your module.

[GRASS-dev] remove raster map in C code

[Luca Delucchi]

Hi devs,

I would like to remove a raster map inside a C module, looking aroung
I found the M_do_remove function used in g.remove and r.reclass. So I
tried to use it but I get error in compilation

OBJ.x86_64-pc-linux-gnu/main.o: In function `main':
main.c:(.text.startup+0x9eb): undefined reference to `M_get_element'
main.c:(.text.startup+0x9f5): undefined reference to `M_do_remove'
collect2: error: ld returned 1 exit status

In the source code of the module I added #include 
that it seems the header containing the definition of M_do_remove.

Any idea?

Thanks in advance
