I am going to use ltrace for some applications like chrome but when I use it, I receive the following error message.
"/usr/bin/google-chrome" is not an ELF file
Does anybody know about the solution? I want to know what functions are exactly called by running an application.
Thanks,
Does anybody know about the solution?
file -L /usr/bin/google-chrome
/usr/bin/google-chrome: Bourne-Again shell script, ASCII text executable
This tells you that google-chrome is a shell script. If you look inside, you'll see that it eventually invokes a real ELF binary (/opt/google/chrome/chrome on my system).
I want to know what functions are exactly called by running an application.
The ltrace command will not show you that. It will only show you what external functions are getting called.

I am making this GUI'ed TCL script with ActiveTCL & Expect.
But for some reason Expect doesn't work with telnet that comes with windows 8 64bit, so I figured a way to use a custom telnet tcl script. It works fine, but I need now to wrap my script with the telnet script and some logo images into a single .exe to run without extra files in directory, but I can't for the life of me get it to work.
I click add files to the tclapp wrapper but it says file not found on the script when it tries to call for the telnet script.
When you wrap Tcl code into a single-file executable, everything goes inside. Scripts, libraries, any images (assuming you're making a GUI), the lot. Tcl transparently extracts things and pretends you've got a real filesystem. However, when you execute a program (whether via exec, open |… or spawn) then the OS must be involved as you are creating a subprocess — the OS is always involved in that, as process management is one of the main things that the OS kernel does — and it needs to have a real executable to run. If you have packaged up your telnet-replacement as its own single-file executable and stored it inside the parent process's VFS, you have to make that subordinate process executable real.
Copy the telnet-executable out to some location (e.g., to the temporary directory, which I think should be described in $::env(TEMP)) and execute that.
set realTelnetExe [file join $::env(TEMP) mytelnet.exe]
file copy .../the/stored/copy/mytelnet.exe $realTelnetExe
spawn $realTelnetExe
# ...
You probably want to file delete the copy once you're done using it.

I'm trying to setup limeJS, the issue is the Internet connection is a problem. I had closure library, box2d, closure compiler and closure templates downloaded separately as .rar files, but I can't find a guide anywhere to set it up like this, everyone just uses(and with reason!!!) the python bin/lime.py init command to get it working. I managed to figure out(yay!) how to setup box2d and closure library but what about the other two?
My laptop is running 64 bits Windows 7. Any help appreciated
All I need is an advice on directory structure, like where to drop the compiler.jar and soy templates .js files, so that when I run the update/create command it doesn't try to download the compiler or templates like it does right now.
I got it working, after taking a quick look at the lime.py file it told me everything I needed, for example both the SoyJs templates file and the compiler need to be in the /path/to/lime/bin/external folder and for example, the lime.py file was expecting a compiler file named compiler-dateOfLatestCompiler.jar instead of compiler.jar.
In general, If you have LimeJS built up in one machine using Python and all, you can just copy paste the whole package anywhere you want and use it just as ususal.
You don't need network once you have all the files/codes for Lime is downloaded.
Infact, you dont even need python for normal development tasks(Python is required to build your js file once you complete development though)
I am porting over an MSBuild script from CCnet to run in Jenkins. The MSBuild project is used to create a deployment package. I would rather have Jenkins drive this process itself but that's a longer term aim.
The problem i am having is (as in the title) when we try and use the HgPull target, from the MSBuild mecurial task (http://msbuildhg.codeplex.com/) we get the error message
HgProcessException: The command hg.exe is not available [Path to project]
I have seen on the project web site that someone solved it by adding the LibraryLocation proeprty to the target but that seems to have made no difference. My target currently looks like this:
Target Name="UpdateSources">
<HgPull
LibraryLocation="C:\Program Files\TortoiseHg\hg.exe"
Force="true"
Update="true"
LocalPath="$(SourcePath)"
/>
<HgUpdate
LibraryLocation="C:\Program Files\TortoiseHg\hg.exe"
Clean="true"
LocalPath="$(SourcePath)"
/>
I'm rather at a loss. Please let me know if you need any more information added to this post to solve this issue. I'm really quite new to MSBuild so really not sure where to start investigating this.
EDIT:
One thing i forgot to mention was that i have tried running the MSbuild command in a console window on the build server and still get the same result. This is really odd given it works fine in CCNet, what magic is CCNet doing to make this command work?
This is now resolved, unfortunately i'm not sure what changes i made to correct these. I believe it may have been down to path separators and whether they where trailing or not in another part of the config file. It does so annoy me with the lack of resilience/consistency between applications where you need to specify paths with/without trailing slashes.
Just a thought, but try adding 'C:\Program Files\TortoiseHg' to your system path. Maybe CCNet has it specified somewhere that Jenkins doesn't have access to.
Also, just for sanity's sake, verify that hg.exe actually exists at that location.
Is there some way to run a command line tool from a client-side script? I want to do something like this:
myutility -flag1 -flag2 inputfile outputfile
with a script in the head of an html file. Is there a way to do it, preferably with JS in Safari?
Yes. That script, myutility needs to be compatible with the server machine your webserver is running on, as well as the script needs to have the correct execution rights. Let me know what kind of script it is so that I can help further, is it a bash script you are trying to run? Perhaps you could do that within your server side language, ie php to make things easier?
I am attempting to send a command to the command line with an air/as3 application.
I have seen some documentation on the invoke command but i am wondering if anyone else has dealt with the same set of circumstances.
basically the user will be checking boxes and filling out a form which will then be written as arguments to an application that will be doing the work. this application accepts these arguments as well as a place to store the output file and processes the file.
so is it possible to send commands to the command line using as3/air and furthermore is it possible to obtain the resulting message from the command line.
I have searched a bit for this sort of information but it seems that google returns a lot of 'how to compile as3 from the command line' tutorials and there are very few articles concerning air/as3 and it's possible interactions with the system's command line.
Thank you in advance,

there is no way to launch apps from AIR (explanation here), nor to send anything to the command line ... however mike chambers created CommandProxy that allows you to do so, interfacing with a C# counterpart ...

AIR 2.0 has Native Process API. Through which now its possible.
