Error : - Waiting for ipc: to terminate

saurabh96

Hello there,

am facing this error or some..i dont know..when am running my Gui to process..My window is getting hang badly and below messgae is prompting on ciw...with different - different ipc: no's.

Waiting for ipc:56 to terminate
Waiting for ipc:56 to terminate
Waiting for ipc:56 to terminate

Is it a machine server issue or something wrong with code..

for launching job am using below code

procedure(Runform(form)
let((cmdPid abcStdout)

cmdPid = ipcBeginProcess("./abc.sh")
ipcWait(cmdPid)
while(abcStdout=ipcReadProcess(cmdPid)
printf("%s" abcStdout ) ;
)
if(!ipcGetExitStatus(cmdPid) == 0 then
error("abc: couldnot run\n")

What happend and how to solve this problem?

Thanks to all.

    This is because you are using ipcWait and the process is blocking. I explained this in my reply to your other post here. You should use an asynchronous approach instead if you want it not to block.

    Thanks Andrew for you valuable feedback!!

    Andrew.. i was wondering when i started to run the process...its showing Error: as requires Tcl 8.5 or higher in CIW.

    i checked with my shell window ..in there tclsh is of version 8.6.

    Is it that skill file is running on its CIW env and taking TCL version less than 8.5?

    How can i run the script in my parent shell window and also check which version tcl version virtuoso is using...like in shell cmd there is "which tclsh"?

    My guess is that the program you're launching is Tcl-based?

    SKILL doesn't care about TCL - it's just that (for various reasons) the "virtuoso" wrappers set the TCL_LIBRARY env var (I'm guessing you're running IC6.1.7 as IC6.1.8 seems to set $TCL_LIBRARY to an 8.6 version of TCL). You can either use ipcBeginProcess("unset TCL_LIBRARY; abc.sh" ...) or just use:

    unsetShellEnvVar("TCL_LIBRARY")

    in your SKILL somewhere to unset it.

    Hi there,

    What I'm doing in such situations:

    From virtuoso open the Library Manager, then from LibManager open a new shell window.
    Here you will have the an identical environment like the one where the script is running.

    It is very handy to do debug in this shell.

    E.g. in my case, I have tcl 8.4 (virtuoso 6.1.6)
    ~ :-)>echo $TCL_LIBRARY
    /opt/..../tools/dfII/etc/tcl8.4

    Hi Andrew,

    Andrew i tried with both above options i.e - unset TCL_LIBRARY and unsetShellEnvVar("TCL_LIBRARY")  ..still issue does not get resolved .

    For more briefing am using cadence-ic-/06.18.0..

    When am running process through my shell window..process is running fine and clean ...but when i am opening shell window through library manger from virtuoso ,as i started running process, Error: as requires Tcl 8.5 or higher is prompting.

    Is there any way or command so that when i start running process it should  run on my parent shell window instead of virtuoso shell window(lib manager)

    Thanks in advance...

    Regards,

    SRV
