[GRASS-user] grass 7 : ERROR: G_malloc

image93 · December 10, 2014, 12:33pm

Hello,

I tried several tests with grass 7 on my windows station.

When i launch the process (v.isochrones), error messages appear, one of them
is ERROR: G_malloc.

Please find below the message.
-------------------------------------------------------------------------------------------------------
ERROR: G_malloc: impossible d'allouer 24576 octets de mémoire à setup.c:124
Invalid map <map_tmp_8612>
Parse error
ERROR: parse error
ERROR: An error occurred while running r.mapcalc
ERROR: Sorry, <type> is not a valid parameter
ERROR: Sorry, <name> is not a valid parameter
(Wed Dec 10 11:32:54 2014) La commande s'est terminée (7 min 20 sec)
--------------------------------------------------------------------------------------------------------

Can you tell me the reason for this message and how to fix problem?

In advance, thank you.

As already answered privately: maybe a region issue. Try using a very coarse resolution and see what happens.

Invalid map <map_tmp_8612>
Parse error
ERROR: parse error
ERROR: An error occurred while running r.mapcalc

This error is a consequence of the previous.

ERROR: Sorry, <type> is not a valid parameter
ERROR: Sorry, <name> is not a valid parameter

Option names were recently changed for g.remove. Which version of grass7 (which svn revision) do you have ?

Try installing a more recent build.

The message indicated that it is not the very latest GRASS GIS 7
version because it would indicate the full path to the failing file,
something like

ERROR: G_malloc: unable to allocate xxx bytes of memory at path/to/file:zz

...

ERROR: Sorry, <type> is not a valid parameter
ERROR: Sorry, <name> is not a valid parameter

Option names were recently changed for g.remove. Which version of grass7
(which svn revision) do you have ?

Try installing a more recent build.

Seems that this will be the solution.

you're running out of memory; try a coarser resolution of your calculation
region or try to reduce your region extent.
