i tried to add :
handle SIGILL nostop
to have more debug ..
i can’t understand the log :/
(gdb) handle SIGILL nostop
Signal Stop Print Pass to program Description
SIGILL No Yes Yes Illegal instruction
(gdb)
(gdb) exec-file r.stream.extract elevation=elevation at PERMANENT accumulation=accum threshold=20 stream_rast=stream_network stream_vect=streams --o
(gdb) r
Starting program: /home/epi/Envs/env1/grass-7.0.svn/bin/r.stream.extract .stream.extract elevation=elevation50m at PERMANENT accumulation=accum threshold=40 stream_rast=stream_network stream_vect=streams --o
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib/arm-linux-gnueabihf/libthread_db.so.1".
Program received signal SIGILL, Illegal instruction.
D2/5: G_file_name(): path = /home/epi/Envs/grass7data/nc_spm_08_grass7/PERMANENT
Description:
Performs stream network extraction.
Keywords:
raster, hydrology, stream network
Usage:
r.stream.extract elevation=name [accumulation=name] [depression=name]
threshold=value [d8cut=value] [mexp=value] [stream_length=value]
[memory=value] [stream_rast=name] [stream_vect=name] [direction=name]
[--overwrite] [--verbose] [--quiet]
Flags:
--o Allow output files to overwrite existing files
--v Verbose module output
--q Quiet module output
Parameters:
elevation Name of input elevation raster map
accumulation Name of input accumulation raster map
Stream extraction will use provided accumulation instead of calculating it a new
depression Name of raster map with real depressions
Streams will not be routed out of real depressions
threshold Minimum flow accumulation for streams
Must be > 0
d8cut Use SFD above this threshold
If accumulation is larger than d8cut, SFD is used instead of MFD. Applies only if no accumulation map is given.
default: infinity
mexp Montgomery exponent for slope, disabled with 0
Montgomery: accumulation is multiplied with pow(slope,mexp) and then compared with threshold.
default: 0
stream_length Delete stream segments shorter than stream_length cells.
Applies only to first-order stream segments (springs/stream heads).
default: 0
memory Maximum memory to be used in MB
default: 300
stream_rast Name for output raster map with unique stream ids
stream_vect Name for output vector map with unique stream ids
direction Name for output raster map with flow direction
ERROR: Option <elevation> does not accept multiple answers
[Inferior 1 (process 7565) exited with code 01]
(gdb)
