Dear David,
The machine I am using has Linux Ubuntu 14.04.4 with IDL 8.4.
The program I am trying to use is related with the analysis of astronomical images: http://spiff.rit.edu/ensemble/
Basically the command that is causing troubles in spawn is called solvepht which runs well directly in the terminal but not when I use it with spawn as:
spawn, 'solvepht infile=multipht.out mconst=12.0 outfile=solvepht.out imfile=solvepht.img sigfile=solvepht.sig'
or
spawn, 'solvepht '+'infile=multipht.out mconst=12.0 outfile=solvepht.out imfile=solvepht.img sigfile=solvepht.sig'
Details of the command can be found at http://spiff.rit.edu/ensemble/ensemble-latest/ensemble.html
After running it with spawn I get the error:
Segmentation fault (core dumped)
I cannot figure it out why it runs well when I run it directly in the shell but not when I run it with spawn.
In the shell it runs as:
solvepht infile=multipht.out mconst=12.0 outfile=solvepht.out imfile=solvepht.img sigfile=solvepht.sig
Any feedback is very welcome.
All the best and thanks in advance.
Roberto.
