[Flightgear-devel] Fgrun output to fgfs
I would like to make a small mod to Fgrun, I would like explore the options of making it drive fgfs multiple machines rather than just one. I spent some time studying the code today and it looked like it runs fgfs as a child process from the run_posix module. Am I on the right track with this assessment? Possibly the best way might be get it write a file rather then do the rest from a script. -- Regards Harry -- The ultimate all-in-one performance toolkit: Intel(R) Parallel Studio XE: Pinpoint memory and threading errors before they happen.

Re: [Flightgear-devel] Fgrun output to fgfs
Hi, yes, you're right, fgrun use the code in run_posix.cxx to create a new fgfs process, but only on Linux. You are allowed to specify the command line you want as executable in the first page, so why not starting your script that way ?

Re: [Flightgear-devel] Fgrun output to fgfs
Hey Thank you Frederic, I get the gist of your message, I point fgrun at a script that will accept the argument string, sort out the options then fire of relevant the command to the various machines. i am all for having a custom script to deal with these unorthodox setups than needlessly tinker with code I don't fully understand. Obviously in a multi machine setup I don't want any io and video options passed but the receiving script can be set to filter with that kind of thing. Would I need to fake fgfs back to fgrun with this script? Or just let the script do its thing and exit normally once its kicked off the various machines. Fgrun then just thinks fgfs terminated normally, albeit rather quick? I suspect in a multi machine setup this is best but the script could hang around till the master machine with the sim engine exits.

It's up to you to block the script or not. fgrun doesn't need anything from the program it launch Regards, -Fred - Harry Campigli a écrit : Hey Thank you Frederic, I get the gist of your message, I point fgrun at a script that will accept the argument string, sort out the options then fire of relevant the command to the various machines. i am all for having a custom script to deal with these unorthodox setups than needlessly tinker with code I don't fully understand.
