Dear all,

I have installed GRASS GIS via elgis.repo (see below) on RHEL5 (Linux wn1.yerphi-cluster.grid.am 2.6.18-274.3.1.el5 #1 SMP Wed Sep 7 10:51:39 CEST 2011 x86_64 x86_64 x86_64 GNU/Linux) version.

I would like to know if you can send me an example with makefile to test.

Regards,
Hrach

I would like to know if you can send me an example with makefile to test.

You can download the standard sample datasets here:
http://grass.fbk.eu/download/data.php
Just untar one of them into your GISDBASE directory and you can start working with that data.

Dear all,

Thanks for your response.
I just wanted to get a simple C example with makefile.
Such as
#include <stdio.h>
#include <stdarg.h>
#include <grass/config.h>
#include <grass/datetime.h>
#include <grass/gisdefs.h>
…

…

Regards,
Hrach

Dear Helmut,

Thanks a lot, but I can’t find Module.make (find / -name Module.make) in order to indicate it in the makefile.
I have installed grass, grass-devel, grass-lib via elgis.repo.

Hi,

2012/1/21 Hrachya Astsatryan <hrach@sci.am>:

I don't see (see below) any Module.make after successful install the grass
from elgis repo.

I don't know about 6.4.1, 6.4.2 seems to install makefiles correctly

I have installed successfully the Grass via elgis.repo (see below)
[root@wn1 grass-6.4.1]# yum list|grep grass|more
grass.x86_64 6.4.1-2.el5.elgis installed
grass-devel.x86_64 6.4.1-2.el5.elgis installed
grass-libs.x86_64 6.4.1-2.el5.elgis installed

So What should I do else?

well, GRASS 6.4.2 has been released yet, you could try to compile
GRASS [1] on your own or to wait for 6.4.2 release. Quick solution
could be to copy `Make` directory from SVN [2] to your `include`
directory. Anyway `grass-devel` seems to be incomplete in this repo.

Hi Hrachya,
make sure you started a valid grass session before you execute any
grass command.
Does only r.example segfault or any other command too?

Hint:
I would avoid to use the root account when working with grass ....

I think that means to start grass, such as type “grass” into your command line and then go through the steps to select your location so as to start a grass session.

Dear all,

Thank you very much for your quick responses.
We are planing to write parallel codes by using GRASS functions.
So we don’t need to use any graphical interface.
So how can I run the r.example in the text mode?

With regards,
Hrach
