ipcBeginProcess not stable on batch mode

WellsJong

Hi, Initially, I use ipcBeginProcess to run the command shown in the bottom using batch mode like the following

icms -nocdsinit -nograph -noblink < /home/irdc/users/wtjong/projects/MSD/shawn/fxdac260/ftc_porting.il

But it doesn't work most of time and the same thing happens using the GUI mode via CIW. Therefore, I remember that from some post, if I don't talk to the process, then just use csh, system, etc. So, I do that and it works perfectly as I expect. But I don't understand why and it is very difficult to trace down the problem because ipcReadProcess(cid) shows nothing at all. Anyone knows how to trace down this problem or any clue to do so? I don't know if I have luck next time if I need to use ipcBeginProcess. Thanks.

 sprintf(info_str "/home/irdc/users/wtjong/work/designkit/optimization/utility/msd2.new/libChar/post_sim_find %s" fc)

 printf("%s\n" info_str)

 ;cid = ipcBeginProcess(info_str);

 ;ipcWaitForProcess(cid)

 system(info_str)

 

 Best Regards, Wells Jong

  • Unfortunately I think too many of the details are missing to know what the problem really is. If the program is complaining about the input file being missing, that's not really anything to do with ipcBeginProcess.

    Your script also has "set LD_LIBRARY_PATH=..." - I presume if it's a csh script, then it should be "setenv LD_LIBRARY_PATH ..." (i.e. setenv not set, and no "=").

    Unfortunately there's too little specific information in your description to be able to diagnose anything.

    The best thing would still be to report this to customer support, even though you have a workaround in place. I'm not convinced it's really a problem with ipcBeginProcess though...
