I have a program that I'd like to run remotely under Valgrind using the Linux Tools remote Valgrind profiler.
I normally debug remotely on a headless server (which has special hardware, so it has to be done remotely on that machine) using RSE, which works fine. Both my machine and the target are Linux machines.
I am now trying to get Valgrind working through Eclipse using the Linux Tools plugin. I have Valgrind 3.10 installed on the remote target machine, and I can run it up manually (outside of Eclipse):
Remotely:
valgrind --vgdb=full --vgdb-error=0 /path/to/app --args
vgdb --port=2345 --pid=XXXX
Locally, connect with gdb with target remote host:2345.
However, I can't work out how to get the "Valgrind (remote)" Eclipse tooling to emulate this, aping the "RemoteTools" setup shown here: .
When I write in a "To:" executable that starts with "rse:/", I get an error in the Profiling Tools settings window top corner saying [Valgrind Options]: Couldn't determine version of Valgrind. What should I write here to get a working remote Valgrind connection?
Haven't found more recent posts on the topic, maybe it will be useful for somebody. I also didn't manage to use remote valgrind plugin with RSE. Seems like only dstore connection type will work for Linux Tools remote valgrind, because SSH or FTP didn't work for me. rseserver requires Perl and Java, and I didn't have them on my target.
I had to use this complicated solution via Launch Group combining this and this solutions. Preconditions: valgrind and vgdb are installed on remote target.
Write a script start_remote_valgrind.sh
set -x
remote_ip=192.168.7.2
remote_port=2222
app_name=test_app
remote_dir=/usr/local/bin/
local_dir=/home/project_name/
ssh -T root#$remote_ip killall -9 vgdb
ssh -T root#$remote_ip killall -9 valgrind
scp $local_dir$app_name root#$remote_ip:$remote_dir$app_name
ssh root#$remote_ip valgrind --vgdb=full --vgdb-error=0 --leak-check=full -v $remote_dir$app_name &
sleep 1
ssh root#$remote_ip vgdb --port=$remote_port
Create debug configuration Run->Debug Configurations->C/C++ remote application:
2.1 On themain tab set the project name and app binary
2.2 In the bottom of the configuration window click "Select Other" link and select "GDB (DSF) manual remote launcher"
2.3 On Debugger tab set GDB debugger for you target platform, command line script .gdbinit.
2.4 On Debugger->connection tab set TCP connection, remote ip and port.
Create external tool Run->external tools->external tools configuration...
Create Launch Group Run->Debug Configurations->Launch Group
external tool must be in Run configuration, remote gdb in Debug. The benefit of this approach is that remote valgrind output is printed in Eclipse console, so you don't need to launch vgdb manually in a separate console and see messages in separate window.

I recently started developing for Node.js/Express with Nodeclipse. I added a run configuration for package.json with goal start. This works as expected, the start command from package.json is executed (node ./bin/www). I can see this command in Eclipse's console view and I can see two node.exe processes appear in Windows Task-Manager. HTTP requests to http://localhost:3000/ are logged in the console.
However, klicking the red "Terminate"-Button in Eclipse's console view leaves the node.exe processes running. Subsequent attempts to start the app fail because the port is already in use.
I do not have this problem when I start the app with npm start in Windows cmd. Stopping the execution with Ctrl+C will also exit the node.exe processes.
This is my IDE-Setup:
Eclipse Luna SR2 (4.4.2) under Windows 7 x64 with jre1.8.0_45
Eclipse was setup this way: extracted eclipse-platform-4.4.2-win32-x86_64.zip (from here), installed Eclipse Marketplace Client, then installed Nodeclipse via Drag&Drop from nodeclipse.org
Node.js version v0.12.2 (for Windows x64)
express-generator (version 4.12.1) is installed globally
How can I make the Terminate button in the console view actually terminating the node.exe processes?
It seems that Eclipse only kills the npm script that is used to start up node. The thing is that Eclipse forcibly kills that script, giving it no chance to send any signals to the node.exe process.
This bug explains why this works this way.
Step 1:
Run command-line as an Administrator. Then run the below mention command. type your port number in yourPortNumber
netstat -ano | findstr :yourPortNumber
Red coloured circled area shows the PID (process identifier)
Step 2 :
Then you execute this command after identify the PID.
taskkill /PID typeyourPIDhere /F
P.S. Run the first command again to check if process is still available or not. You'll get empty line if process is successfully ended.
is there a posibility to make eclipse PyDev use a remote Python interpreter?
I would like to do this, as the Linux Server I want to connect to has several optimization solvers (CPLEX, GUROBI etc.) running, that my script uses.
Currently I use eclipse locally to write the scripts, then copy all the files to the remote machine, log in using ssh and execute the scripts there with "python script.py".
Instead I hope to click the "run" button and just have everything executed within my eclipse IDE.
Thanks
Unfortunately no. You can remotely connect to your Linux server via Remote System Explorer (RSE). But can't use it as a remote interpreter. I use Pycharm. You can use the free Community Edition or the Professional Edition for which you have to pay for it. It is not that expensive and it has been working great for me.
As Adel says, this is probably not possible with the Remote System Explorer, or the normal Run button,
but you can automate the process you currently use. I had to do this for a few weeks when the fan was broken
in my laptop, and doing any significant computation there made it overheat and poweroff, so I just ran
everything on my work machine.
You can use the External Tools mechanism to run a short script that syncs your code to the remote server,
runs your script, then syncs back any output files to your local machine. My script looks like this,
is stored in $HOME/bin/runremote.sh, and is executable (chmod +x runremote.sh)
fp="$1" # Local path to the script we want to run--for now,
# this is the only command I pass in from Eclipse, but you could add others if so inclined.
# My home directory is a little different on my local machine than on the remote,
# but otherwise things are in the same place. Adjust as needed.
fp=`python -c "print '$fp'.replace('/home/tsbertalan', '/home/oakridge/bertalan')"`
# Run the synchronization. I use Unison, but you could use something else,
# like two calls to rsync, or a series of scp commands.
reposync >/dev/null # The redirection assumes your sync command will print errors properly on stderr.
cd='cd '`dirname $fp`
# I use a virtual environment on the remote server, since I don't have root access to install
# packages globally. But this could be any set-up command you want to run on the remote.
# A good alternative would be `source $HOME/.profile` or `~/.bashrc`.
act='source /home/oakridge/bertalan/bin/activate'
fname="`basename $fp`"
cmd="$act ; $cd ; python $fname"
# Run the command remotely. The -X forwards X11 windows, so you can see your Matplotlib plots.
# One difficulty with this method is that you might not see all your output just as it is created.
ssh bertalan#remote.server.edu -X "$cmd"
sleep 1
# My synchronization script is bidirectional, but you could just use rsync with the arguments flipped.
reposync >/dev/null
If you don't use linux or OSX locally, you'll probably have to use MinGW or Cygwin or whatever to get
this working. Or, since you appear to have a working Python interpreter, you could write an
equivalent script in Python, make it executable (by the file properties dialog in Explorer, I think),
and add a #!/path/to/python line at the top. I don't use Windows regularly, so I can't really help with that.
To use this in Eclipse, go to Run > External Tools > External Tools Configurations.... Add a new tools
whose Location is the path to your script, and whose first Argument is ${resource_loc}.
You can then use it with Run > External Tools > [first item], or bind it to a keyboard shortcut (I used F12)
by going to Windows > Preferences > Keys, and searching for "Run Last Launched External Tool". Presumably you'll
have to go through the menus first to make this the "Last Launched" external tool.
Before each debugging cycle I have to run gdbserver on remote target (Linux). So I was thinking to make script that would call python program that would connect over ssh and would run gdbserver.
I cant find any options to run command before debug and I also try to change .gdbinit file but I am unable tu run python script whit that. Since I am using crosscompiler I cant to get other gdb whit such support.
You don't need to run Python to invoke an external command from GDB. This (in .gdbinit) should work:
shell ssh remote-host gdbserver :12345 /path/to/binary/on/remote &
target remote remote-host:12345
If you do need more complicated ssh setup and need Python for that, you can certainly get it with
shell python your_script.py
If you can't get any external program called from your gdbinit, I see one way of doing it within Eclipse that might work (I didn't tested) but it is not really straightforward...
Create an External Tool configuration that launches your gdbserver program (Python or whatever command line script)
Create a C/C++ application launcher that launch your application to debug
Create a launch group that will call the two previously configured configurations.
Launch the group in debug mode
Eclipse 4.7.0 can connect to SSH and launch gdbserver automatically with the automatic launcher set when creating a new debug connection, without the need for any custom scripts.
I have explained the setup in great detail at: Remote debugging C++ applications with Eclipse CDT/RSE/RDT
I'm trying to debug an application remotely with Eclipse CDT.
I got gdbserver and gdb running so I can debug via command line.
I'd like to integrate this stuff into Eclipse. I create a .gdbinit file in my home directory which is corretly loaded by Eclipse. However when i start the debug process I get
"the remote target does not support run"
From the command line, I can use "continue" instead, which work. However I cannot use this alternative from CDT since it is somehow automated.
How can I get Eclipse to use continue instead of run, or how can I make my gdbserver to accept run instead of continue?
If your gdb is recent enough to support the alias command, then you can include the line....
alias run = continue
in your .gdbinit file.
Here is my situation:
I am developing PHP CLI scripts on a distant server using Eclipse IDE with the RSE plugin (allows to edit files directly on the server).
Now I need to debug these scripts in a similar fashion than in Java (break points, show the variables content, ...).
I found something that could do the job: XDebug and PDT (Eclipse plugin). The problem is that when I try to launch the debug mode Eclipse says that there is no PHP debugger on the local machine. I guess it should be installed on the server machine.
I would like to know if it's possible to use PDT and XDebug to debug remote scripts and, if it's the case, how to configure them to do so. If not, I'd like to know if other solutions exist. It seems like XDebug uses TCP so it should be possible to debug remotely. I can change my IDE if necessary.
The server runs Ubuntu 10.04 with php5-cli and the dev machine with eclipse runs Win7 32bit.
Thanks
Yes this is possible, you need to enable xdebug in the remote server's PHP.ini file and make sure that the xdebug port (default 9000) is not blocked by any firewalls.
xdebug's page on setting up remote debugging.
Here is the complete procedure for the people who have the same problem:
First, install RSE by following the instructions on this website: http://help.eclipse.org/galileo/index.jsp?topic=/org.eclipse.rse.doc.user/gettingstarted/g1installing.html
Follow the instructions on this HowTo to install XDebug on the server:
http://ubuntuforums.org/showthread.php?t=525257
Install PDT on Eclipse and do the following changes:
- under Windows/Preferences, go under PHP/Debug and change PHP Debugger to XDebug
- under Windows/Preferences, go under PHP/Debug/Installed Debuggers and configure XDebug. Change the field "Accept remote session (JIT)" to "any".
Open the Remote System Explorer perspective, select your scripts directories and create a project from them (Right Click, Create Remote Project). It will now appear in the PHP perspective.
Let Eclipse run and go to the server (e.g. via SSH). Run the script you want to debug. A Window will then appear on Eclipse proposing you to choose with which "local" (remote via RSE in our case) file you want to link the running script to. Normally, the default script proposed should be the correct one, because it is the one running on the server.
You should now have visual debugging with Eclipse for your PHP-CLI scripts!
Do you want to debug while being able to interact with the script on CLI or do you just want to start it and then step through the code? I guess your question is referring to the problem that you can't access the script directly through a URL. If that's your problem, then I guess the easiest solution would be to debug a usual PHP-web-site which requires your script. Then you can launch XDebug with that web-site initially and step into the script through the require/include-statement.
index.php:
<?php require_once("../../../../../dir1/[...]/cliscript.php");
