Re: [GRASS-user] r.example
Hi Markus, yes, I started GRASS and selected the location 3763_Portugal, so I guess it means i was in a GRASS session? Anyway, I followed the link you provided and finally managed to put it to work! Yeah! I just type r.example and it runs. I have some more questions about writing in rasters but will create a new thread. Thank you all for your help! Cheers, Pedro.

[GRASS-user] changing raster values in r.example
Hi.
I'm starting to write a simple program based on r.example.
For now the goal is to read a DEM file, change some values, and write out
another DEM file with the changed values.
The r.example creates the second DEM file but with the default region (how can
I change the region?) and does nothing to the values.
So, I tried this:
//
for (row = 100; row 200; row++)
{
if (G_get_raster_row(infd, inrast, row, data_type) 0)
G_fatal_error(_(Unable to read raster map %s row
%d), name, row);
for (col = 240; col 350; col++) {
((CELL *) outrast)[col] = 2000;
}
if( G_put_raster_row(outfd, outrast, data_type) 0 ) {
G_fatal_error(_(Failed writing raster map %s),
result);
}
}
//
But it's not writing the changed values.
I even tried changing the r.example as little as possible just changing this
function:
//
CELL c_calc(CELL x)
{
x = x + 2000;
return x;
}
//
But still didn't work. Any clues why it's not writing?
Thanks

Yeah!!! So far, so good.
('make distclean' only works if ./configure has already run)
Ok.
I guess it compiled, as I see an object file:
...

But where is the executable?
in $GISBASE/bin/

[GRASS-user] r.example
Hi! I'm a newbie to GRASS and would like to do some C programming with its modules. I'm having some troubles putting to work just a simple raster example (r.example)! I'm on a Debian squeeze machine and installed Quantum GIS with the GRASS plug-in. Nevertheless I installed GRASS (version 6.4.0~rc6+42329-3) via Synaptic Package Manager because I just want to use GRASS modules. I checked where it was installed and the grass64 is in usr/bin but many functions are in usr/lib/grass64/bin. From a terminal window I can call GRASS just by typing grass. So far so good. Then, I looked for a simple example for reading a raster file in C and found out about the r.example (although didn't find it in my local installment). So, I downloaded the GRASS source code version 6.4.3RC3 and unzipped it to a folder placed in my Desktop. Now, from a Terminal window, I went to the r.example directory and typed make. Here is the result: pedro@PedroHost:~/Desktop/grass-6.4.3RC3/doc/raster/r.example$ make make: @GRASS_HOME@/dist.@host@/tools/g.echo@EXEEXT@: Command not found make: @GRASS_HOME@/dist.@host@/tools/g.echo@EXEEXT@: Command not found mkdir -p @GRASS_HOME@/bin.@host@ mkdir -p @GRASS_HOME@/dist.@host@/include/grass mkdir -p @GRASS_HOME@/dist.@host@/lib mkdir -p @GRASS_HOME@/dist.@host@/bin mkdir -p @GRASS_HOME@/dist.@host@/etc mkdir -p @GRASS_HOME@/dist.@host@/driver mkdir -p @GRASS_HOME@/dist.@host@/driver/db mkdir -p @GRASS_HOME@/dist.@host@/fonts test -d OBJ.@host@ || mkdir -p OBJ.@host@ /bin/sh: CC@: not found make: *** [OBJ.@host@/main.o] Error 127 Am I doing something wrong, do I need to install anything else or configure something?
