Hi devs,
I’m trying to use r.li.* modules to develop an example for a course. I am currently working in trunk, though I had to create the config files in 74 rel branch because I get an error in trunk (reported already in [0]).
Now, when I try to use r.li.shannon for example (though it happens with other modules as well), I get the following error:
r.li.shannon --overwrite input=landclass96@PERMANENT config=forest_mov_win output=forest_mov_win_sh
munmap_chunk(): invalid pointer <<<— THIS
The map is created but not displayed, with errors related to decompression in the GUI console:
Failed to run command ‘d.rast map=forest_mov_win_sh@user1’. Details:
GRASS_INFO_WARNING(12641,1): LZ4 decompression error
GRASS_INFO_END(12641,1)
GRASS_INFO_ERROR(12641,2): Error uncompressing null data for row 474 of <forest_mov_win_sh>
GRASS_INFO_END(12641,2)
Also…
GRASS 7.7.svn (nc_spm_08_grass7):~ > r.univar forest_mov_win_sh
WARNING: LZ4 decompression error
ERROR: Error uncompressing null data for row 474 of <forest_mov_win_sh>
Why is this? I didn’t set any env var for compression.
A different case is:
GRASS 7.7.svn (nc_spm_08_grass7):~ > r.mapcalc “forest = if(landclass96 == 5, 1, null())”
GRASS 7.7.svn (nc_spm_08_grass7):~ > r.li.edgedensity input=forest config=forest_mov_win output=forest_edge_mw
double free or corruption (!prev) <<<— THIS
Aborted (core dumped)
… but map is created and no error related to compression.
Doing something equivalent, I get a different error (same as the first one):
r.li.edgedensity --verbose input=landclass96@PERMANENT config=forest_mov_win output=forest_edge patch_type=5
munmap_chunk(): invalid pointer <<<— THIS
Aborted (core dumped)
GRASS 7.7.svn (nc_spm_08_grass7):~ > r.univar forest_edge
WARNING: LZ4 decompression error
ERROR: Error uncompressing null data for row 474 of <forest_edge>
What am I doing wrong? Does anyone know the trick to use these modules?
Thanks much in advance,
Vero
