[GRASS-user] Re: [GRASS-dev] Compiling r.example in LINUX

Antonio_Rocha1 · January 26, 2010, 9:40am

Greetings Glynn

The thing is that I went here: http://trac.osgeo.org/grass/browser/grass/trunk/doc/raster and I donwloaded the r.example that is there.
At least I didn«t saw any information regarding GRASS version :(.

Now I realize thatr the trunk relates with 7.0 version and in Branches I can find 6.4 version.

Ok After I did this:
sudo make -C Desktop/GRASS_dvp/r.example/ MODULE_TOPDIR=/usr/local/grass-6.4.0svn

Instead of putting r.example in /usr/local/grass-6.4.0svn my r.example was putted in
/home/anrr/Downloads/grass-6.4.svn_src_snapshot_2010_01_16-2/dist.i686-pc-linux-gnu
this is the path to my snapshot from which I installed grass-6.4.0svn.
Shouldn't it be placed in usr/local/grass-6.4.0svn? Because altough it has been compiled it's not available to be used.

Thanks for your help.
Antonio

By the way, the error text might be helpful:

You're trying to compile an example written for 7.0 against 6.4.

A lot has changed between 7.0 and 6.x. E.g. all of the raster-specific
functions have been removed from lib/gis and moved to lib/raster, and
renamed from G_* to Rast_*.

The r.example source code is included in the GRASS source tree, in
doc/raster/r.example. The version in the 6.4 source tree should
compile against 6.4.

The *.make files continue to reflect the build directory; you'll need
to override certain other variables, e.g. GRASS_HOME and RUN_GISBASE.

There may be other issues; the ability to build modules outside of the
source tree against an installed version of GRASS is a relatively
recent feature, and may still have bugs.

Hi All
Ok I've changed my ARCH_DISTDIR, ARCH_BINDIR (GRASS.MAKE), GRASS_HOME and RUN_GISBASE (PLATFORM.MAKE) in order to point to my grass-6.4.0svn installation instead of my Snapshot folder.

Is it helpful to create a Wiki regarding this matters? (two other persons sent me PMs regarding this questions with the same questions).

Thank you Glynn for your help.

Best regards,
Antonio

Regarding this issue.
Although it's compiling r.example I'm getting the following error:
ERROR: G_getenv(): Variable LOCATION_NAME not set

What does this mean? I need to have a demolocation folder in my GRASSsvn6.4.0 folder?

Thanks

The default rule for a module attempts to build the HTML
documentation, which involves running the program with the
--html-description flag to obtain the module/option/flag descriptions.

Running the module requires that GISRC is set and refers to a file
containing settings for at least GISDBASE, LOCATION_NAME and MAPSET. I
don't recall whether those values need to be valid, or just exist.

The rule sets GISRC from RUN_GISRC, which is defined as:

RUN_GISRC = ${ARCH_DISTDIR}/demolocation/.grassrc${GRASS_VERSION_MAJOR}${GRASS_VERSION_MINOR}

You can either copy the demolocation directory from the source tree,
or just change the value of RUN_GISRC to point to a suitable file.
