I want to launch other executable from my cpp code. I am aware that system() call may do this , But, problem is that , I want my cpp code to capture the standard hat "called" program is writing to stdout.
View 2 RepliesI've been requested to modify a perl backup script we use which mounts a networked NAS machine. The actual mount command is called inside a system() command. In testing, I can do a test of the return value, so I'm able to tell whether or not I've mounted properly, but I can't make heads or tails out of the return on deliberate errors. (Such as mounting a non-existent box.) I'm displaying the returned value, which is 256 in my tests. The man page for mount listed error messages with values from 1 to 64, but no higher. Am I drawing this error value from the system command somehow? And what would be the best way to determine what this error means?

I am working on a custom hand-held device which runs a variant of Ubuntu Linux, 2.6.18. I have a set of 4 binary files (for oprofile) which have been known to run in this environment, but when I copy them to /usr/bin, I can't run them: I get this message;root@ldogberry:/usr/bin# ./ophelp-sh: ./ophelp: not foundThis happens when I specify the full path, when I run from the /usr/bin directory -- it happens no matter what. Bash even does command-line completion on the file -- and then turns around and instantly claims the file is not found.

The problem come out when i put this script in a crontab schedulation. The result in this case is that java do not execute the system command. I think it depends on crontab
View 4 Replies View RelatedWhen I mistype a name of an executable program in terminal, ubuntu tries to search for similar programs in packages and then suggests names. This takes time, slowing down work and entirely useless for me. How to turn this feature off?
I personally can't even find a reason for implementing this feature and rather making it turned on by default. If someone needs a tool, he/she can search through packages.

I have been trying to get Wine to work in Fedora and have had nothing but problems. First of all, I can't open executables in the GUI. If I try, I get a message that says, "The program start.exe has encountered a serious problem and needs to close."
I can open .exe's in the terminal, but when I tried to install iTunes it wasn't able to complete the installation. I got an error message from SELinux that said something about a memory error, and then it asked me if I wanted to turn off some sort of memory management setting. I said yes and it asked me for my password, which I gave, and then it said "unable to grant access". It no longer gives me this error message (that's why I can't recall what it said verbatim), and instead just hangs at the point where I got the error message before. I've tried using Wine in Ubuntu before and could never get anything working in a half-decent way, so this isn't a big surprise.
I'm wondering why in order to run executables after compilation i have to type >"./executableName" I want it to type it just like >"executableName" (with no "./")

I just installed the xubuntu-desktop package on my netbook (running UNR), and I've got one major complaint about xfce.
I can't right-click on icons in the Applications menu and add them to the launcher!Instead I have to know the location of the executable for the application, so that I can right-click the panel, add a launcher, and then type the location of the executable in and manually select an icon for it...Of course it probably wouldn't be a pain if I could find everything. In Windows, if I want to know the location of a program that's running, I just open Task Manager, right-click the application, and select Properties.
Is there some equivalent or command-line way of finding the location of a running application in Linux?
A few I'd like to know the location of are:
1) Gnome System Monitor
2) Terminal
3) Swiftfox
... and I'll probably think of others.
Even though I'm using XFCE, I figured this fell under the "all variants" category since my main question is just how to find the locations of executables...
I'm trying to run flasm from the terminal prompt but I don't really know what I'm doing.

I want to install an executeable and I am not sure how to do this. My intuition was to copy the executeable in the /usr/bin folder, but when I call it now, it says permission denied (and obviously I don't want to call the program with sudo every time).

The last thing I compiled with an executable was BloodFrontier, and it works perfectly.
