Linux - nohup - standalone

I have two questions : I use a compiled program from my .m code. I'm under linux (ubuntu) and I am using MAtlab 11b and MCR v716.

_

Here are my questions : 1) Even if I did set the environment variable correctly (I think), I still need to specify the directory of the MCR when starting the compiled program ( ./run_myprogram.sh MCRlocation/ 'params'). Is it normal ? Do you have an idea where it could come from ?

_

2) I want to run program through the network on a distant machine. For this, with my normal program in C or fortran, I was used to connect via ssh and then use 'nohup'( command : nohup ./myprogram.out). It turns out it does not work with matlab compiled files while it is OK with my C/fortram program. I guess this might be due to the dynamic compilation, even if I am not sure. Do you have any idea ? I did try to rewire the standard io of the shell without success. Is there a scpecial link to rewire with MCR ?

I used : nohup runscript.sh ~/MCRlocation/ 'in_params1' 'in_params2' >screen.out 2> sortie.err </dev/null &. I also tried several variants with no wiring of io and a program without input parameters. No effect, nohup does not work.

The effect is always the same. I run the script with nohup -> OK. I logout using exit -> display logout but does not come back to my distant shell. close the windows -> process stopped (see it with top command)... any idea ? It is quite annoying situation.

If I ask the run_script to verboe (-xv) it tells me 'segmentation fault' when I exit...

Thank you by advance for your help,

best regards,

Francois.

I have never used nohup, but I have used screen.
