I just installed Maya 2009 on Fedora 13.It seemed to run the RPM install fine, but when I go to Applications > Graphics > MayaI an error:Could not launch 'Autodesk Maya 2009 (64-bit) Failed to execute child process "/usr/autodesk/aya/bin/maya"(no such file or directory)I browsed to this location in the file browser and there definately is a file called maya in "bin"
There seems to be a common solution to get the webcam working with Skype - rather than launching with Skype you launch with LD_PRELOAD=/usr/lib32/libv4l/v4l2convert.so skype - so far so good. When I do this I get the error There was an error launching the application. Details: Failed to execute child process "LD_PRELOAD=/usr/lib32/libv4l/v4l2convert.so" (No such file or directory). But I do have that directory and file on my system.
A ubuntu community doc talks about the terminal command sudo ld.so.preload-manager when I action this I get sudo ld.so.preload-manager /usr/lib/libv4l/v4l1compat.so [sudo] password for dad: sudo: ld.so.preload-manager: command not found
Failed to execute child process "gnome-help" (No such file or directory)I get this error when clicking on the Help button in, for example, the preferences dialog box like for the Time and Date panel.I cannot find anything in the Synaptic Pkg. Mgr. or Ubuntu Software Center that indicates "gnome-help".
I've installed MatLab in my Acer Aspire one netbook which runs karmic. Does anyone know what can cause this error message from appearing when i click on the icon? Could not launch 'MATLAB R2009a' Failed to execute child process "matlab" (No such file or directory)
I am running F11 and I want to mount an FTP, but when I try to connect to an ftp server using Places -> Connect to Server, or the bookmarks I made I get an error that says 'Failed to execute child process "/usr/lib/firefox-3.5/firefox" (No such file or directory)' and sometimes it mounts anyway, but most the time it doesn't, and it never connects to the folder I asked it to, I just have to open the mount and navigate to it. I figure this happened because Firefox upgraded to 3.5.1 and the folder is now /usr/lib/firefox-3.5.1/firefox, but I don't know how to update this so that it looks in the right location.
Just figured this one out and thought I'd post it here in case it helped someone else. Skype just upgraded itself from 2.1 to 2.2. After upgrading it didn't start, and I got the message
"failed to execute child process skype-wrapper" First test out if skype runs from the command line, by running this in a terminal
Code: skype & If it runs, you're good to go: simply right click on the menu, locate your entry for skype and change the command to launch it from skype-wrapper to skype. The reason for this is that in the 2.1 version, skype needed a script called skype-wrapper to set some varibles before start up. Upgrading removes the script, but failed to update the menu entry.
I am using Ubuntu 10.04 LTS. Two days ago I updated using update manager. After that I can not boot Ubuntu. When I trying to boot system showing message " Ubuntu is running in low-graphics mode Your screen, graphics card and input device settings could not be detected correctly. You will need to configure these yourself" But I can not configure it.I can not boot to 'recovery mode' also
fsck from util-linux-ng 2.17.2 /dev/sda6: clean, 304282/1680960 files, 2964945/6723194 blocks init: Failed to spawn ufw pre-start process: unable to execute: No such file or directory
I just updated from 9.04 to 9.10 (it's a long story, and I still can't go beyond 2.30).The update got rid of WICD, which is what I used and installed network-manager. Network-manager was not working at all, so I uninstalled it again and installed WICD. I could connect perfectly and had no problems.However, now the computer hangs during boot, saying that init can't start network-manager. I assume that something went wrong during the uninstalling process, since it wasn't updated.
This is the message: init: Failed to spawn network-manager main process: unable to execute: No such file or directory.
So how do I update it or manually change it so it stops requesting network-manager?
My machine is dual booted with Fedora 14 and RHEL 6. (I have only installed Red Hat because I am studying for RHCE). Just now I tried to install the Banshee player on my Red Hat OS. I ran various scripts inside the directory to see what really happens and after I ran the 'Makefile.in' file my terminal froze. It displayed '/bin/ not found'Then i restarted my computer and I got the following messages:
init: Failed to spawn readahead-collector main process: unable to execute: no such file or directory init: Failed to spawn rcS main process: unable to execute: No such file or directory init: Failed to spawn readahead main process: unable to execute: No such file or directory
I tried run level 1 and run level 3 but I get the same error messages.
I am trying to create a launcher in Fedora 13 which will run a simple script named proj4a. I run this script from the command line as follows: $ /home/enowak/proj4a >/home/enowak/proj4a_out where proj4a is an executable file in my home directory and the output goes into a file, proj4a_out, in my home directory. Everything works fine.
I created a launcher called Proj4a and in the command field I entered the following: '/home/enowak/proj4a >/home/enowak/proj4a_out' When I click on the launcher it comes back with the following: There was an error launching the application. Details: Failed to execute child process "/home/enowak/proj4a >/home/enowak/proj4a_out" (No such file or directory) I can't for the life of me figure out what is wrong here. Does anybody see what I'm missing?
I just upgraded Xubuntu from 10.04 LTS to 11.04 and I am no longer able to mount removable media from the "places" menu. The message I get:
"Failed to execute child process exo-mount (No such file or directory)"
I assume some wrapper process is attempting to execute a program called "exo-mount," but no such program exists anywhere in the repositories, according to a search with apt-file. The "exo-utils" package used to contain exo-mount, but the program no longer exists in that package.
I just installed a program and do not know what is causing this error. When I run it from the applications menu I get the following error "Could not launch 'FirstClass Client' :Failed to execute child process "/opt/firstclass/fcc" (No such file or directory)". I opened up a terminal and looked at the location. The file is there. I do not know much at all in this area but do not understand why this error is occurring.
I was wondering if 7735, 7736, 7737, 7743 were really processes. Then I checked /proc, I could cd to /proc/7735, /proc/7736, etc, but I could not ls them out. I looked at the man page of "pstree", it says,
Child threads of a process are found under the parent process and are shown with the process name in curly braces, e.g.
So, what does all this mean? Does it mean that 7735, 7736, 7737, 7743 are just threads but not processes? If so, why could I cd to /proc/<id> but not see them in "ps -elf".
Parent: chid_pid=4356 i=0 parent's pid=4355 This is child 4356 i=0 This is child 4357 i=1
I can observe instead of two children(as I expect) processes there are three. This is because child process 4356 creates its own child. Why all the messages of the type "This is child X i=Y" are concentrated one under another? How exactly fork works? Is affected by the fact that I have a dual-core processor?
I have an Acer 9410Z laptop that I believe is running the Maverick Meerkat version of Ubuntu Studio. I just did an upgrade using Synaptic. I get to GRUB, but When I try to boot 2.6.35-22 (or the recovery mode or a real time kernel I had installed )I get the error:
INIT: Failed to spawn ureadahead main process. No such file or directory I then get the Ubuntu Studio splash screen for 2 seconds but then instead of a normal boot I end up in the terminal.
Description of what the code does or what i intended to do:
1. Created a child process from parent process using 'fork()'
2. Sent a signal 'SIGALRM' from child process to parent process using 'sigqueue' function.
(The Third parameter of 'siqueue' function contains the message (message msg) which the child process wants to send to the parent process.'msg' is a stucture instance containing a) pid of child and b) string) 5. Print the 'msg' sent by child process inside the signal handler function 'sig_action_function' of the parent process I am getting some junk value when this line is executed
I expected to get the pid of child process, which the child process sent to parent process through the signal.
Means I want to execute two executables one by one at the same time as shown below:execute1 execute2these are two executables. but the second one is executed after 1st one is closed is there any way two execute both.One way isgnome-terminal -e execute1execute2but here i want to hide the terminal window..........
I have a doubt about signals in C programming. I have done this little program to explain it. It creates a child process with fork and, when the child ends, receives the SIGCHLD signal and wait for its termination.Ok, quite easy, BUT when I execute this code the SIGCHLD signal is received twice, first as an error (returns -1) and the second one to finish the child process.I don't understand the meaning of the first received signal. Why is it generated? Is the code wrong? (if you add the SIGINT and press Ctrl+C during the execution it also receives two signals instead of one)
2. Child process use execl()command to run a java program.using execl("java -jar st.jar");
3. When i killed the child process programmatically using C system functions it only kills the child process. But the Java process which is created by the child process keeps on running at the backend.
how can i kill these child of child processes. when i kill the child process. I tried Kill commands doesnot work... IS there any command to kill the entire processtree.
I need to disable file access (fopen, freopen, open etc) for application which is running under chroot jail and with restrictions (rlimit) via execv. Before that I redirected stdin/out to files within jail. I tried this:
Code: // Redirect stdin/stdout to files int fd = open (file_input, O_RDONLY); if (fd < 0) fatal_error ("input open failed!");
Whenever execute the below scriptlet with out proper file name it deletes /tmp directory .I guess this is because value of variable a didnt get initialized and there for rm -rf /tmp/ get executed and entire /tmp directory get deleted.How would i avoid any empty variables to be used in script? as this is a classic case of destructive script.
Code: #!/bin/bash echo "Enter file to delete from tmp"
I have ubuntu 10.04.1 and a H.P.psc 1311 all-in-one printer scanner.Printer works ok but when trying to scan,with xsane,it goes through the scanning process and an image of the document comes up on the screen.
When I try to save this image to desktop or file/folder whatever I get the message; "Child Process Error. Failed to execute OCR command:GOCR:no such file or directory."
I want to kill parent process after "fork()" method. but if I kill parent process with "exit(0)" method, main() thread is terminated as well so child prosess doesn't work anymore. Is there any way to kill only parent process without affecting to child process?
In my program, I fork() to get a child process. Because of some problem, child process terminates by a segmentation fault. Parent process is still running. I have compiled my code with -g option. I have done: ulimit -c unlimited. I am not getting core dump of the child process. How can I get the core dump of child process?
I have created three child process from one parent. And different child has different functions. Child 2 has got function to load file called "wc" to count file1 and and its required to get their files by command line arguments. I can get the files through command line but couldn't get the files when child 2 process start.
i am trying to install symantec endpoint on a linux server by this command rpm -ivh sav-1.0.3-8.i386.rpm but it gives me the following error error: unpacking of archive failed on file /opt/Symantec/bin/navdefutil;4ceb8d6b: cpio: mkdir failed - No such file or directory
I have a script that calls other scripts/commands which may or may not spawn other process. From my understanding, when I do a ps -ef, the highest numbered process ID is supposed to be the parent ID of all the other related child processes, is this correct? In most or all circumstances, I do a ps -ef | grep <processid> of my script and anything that spawns off that process IDs I assumed are the child processes of my script. If I want to terminate my script and all other child processes, then I kill the parent ID which is the highest numbered PID and this will subsequently kill all other child process IDs, is this correct?
Now, my question is whether there is any quick way of showing what are the child processes of a parent ID instead of what am currently doing now which is visually checking which one is the parent ID and "assuming" that the highest numbered PID is the parent ID of all the other processes. Below is a sample output of running ps -ef | grep exp | grep -v grep. I assume from the output below that the parent process/ID is PID 11322, is that correct?
I wonder how one can, if at all, run an X program in the background *in an emulator sub-shell process*. What I mean is to launch a program in an emulator, e.g, by xterm -e gedit
but with gedit (in this example) running in the background from inside the xterm sub-process, so that the xterm will accept other commands. In the above, gedit will run in the foreground, and of course, if you do xterm -e gedit &
then xterm will run in the background, not gedit.In short, I would like to achieve the same thing as "gedit &" as you manually do in xterm, but from another shell. What I aim to do is write an X init script to achieve this result (to have the emulator open and a program or two running from it, in the background, at the X startup).
I'm studying about signal in Linux Kernel and I got a problem about signal handler and output buffer.
I just want to know about stdout buffer related parent process and child process.
The problem is - parent process received SIGINT signal_handler that I implement is called. And after signal_handler is called, it print string "pid : xxx state : RUNNING" ... but after end of signal_handler function, child process might be print string but it isn't print at all.
I'm not asking right code, but I want to know why is this happened and concepts about signal handler, buffer - between parent process and child process.
