I have the following boxes:
a) A Windows box with Eclipse CDT,
b) A Linux box, accessible for me only via SSH.
Both the compiler and the hardware required to build and run my project is only on machine B.
I'd like to work "transparently" from a Windows box on that project using Eclipse CDT and be able to build, run and debug the project remotely from within the IDE.
How do I set up that:
The building will work? Any simpler solutions than writing a local makefile which would rsync the project and then call a remote makefile to initiate the actual build? Does Eclipse managed build have a feature for that?
The debugging will work?
Preferably - the Eclipse CDT code indexing will work? Do I have to copy all required header files from machine B to machine A and add them to include path manually?
Try the Remote System Explorer (RSE). It's a set of plug-ins to do exactly what you want.
RSE may already be included in your current Eclipse installation. To check in Eclipse Indigo go to Window > Open Perspective > Other... and choose Remote System Explorer from the Open Perspective dialog to open the RSE perspective.
To create an SSH remote project from the RSE perspective in Eclipse:
Define a new connection and choose SSH Only from the Select Remote System Type screen in the New Connection dialog.
Enter the connection information then choose Finish.
Connect to the new host. (Assumes SSH keys are already setup.)
Once connected, drill down into the host's Sftp Files, choose a folder and select Create Remote Project from the item's context menu. (Wait as the remote project is created.)
If done correctly, there should now be a new remote project accessible from the Project Explorer and other perspectives within eclipse. With the SSH connection set-up correctly passwords can be made an optional part of the normal SSH authentication process. A remote project with Eclipse via SSH is now created.
The very simplest way would be to run Eclipse CDT on the Linux Box and use either X11-Forwarding or remote desktop software such as VNC.
This, of course, is only possible when you Eclipse is present on the Linux box and your network connection to the box is sufficiently fast.
The advantage is that, due to everything being local, you won't have synchronization issues, and you don't get any awkward cross-platform issues.
If you have no eclipse on the box, you could thinking of sharing your linux working directory via SMB (or SSHFS) and access it from your windows machine, but that would require quite some setup.
Both would be better than having two copies, especially when it's cross-platform.
I'm in the same spot myself (or was), FWIW I ended up checking out to a samba share on the Linux host and editing that share locally on the Windows machine with notepad++, then I compiled on the Linux box via PuTTY. (We weren't allowed to update the ten y/o versions of the editors on the Linux host and it didn't have Java, so I gave up on X11 forwarding)
Now... I run modern Linux in a VM on my Windows host, add all the tools I want (e.g. CDT) to the VM and then I checkout and build in a chroot jail that closely resembles the RTE.
It's a clunky solution but I thought I'd throw it in to the mix.
My solution is similar to the SAMBA one except using sshfs. Mount my remote server with sshfs, open my makefile project on the remote machine. Go from there.
It seems I can run a GUI frontend to mercurial this way as well.
Building my remote code is as simple as: ssh address remote_make_command
I am looking for a decent way to debug though. Possibly via gdbserver?
I tried ssh -X but it was unbearably slow.
I also tried RSE, but it didn't even support building the project with a Makefile (I'm being told that this has changed since I posted my answer, but I haven't tried that out)
I read that NX is faster than X11 forwarding, but I couldn't get it to work.
Finally, I found out that my server supports X2Go (the link has install instructions if yours does not). Now I only had to:
download and unpack Eclipse on the server,
install X2Go on my local machine (sudo apt-get install x2goclient on Ubuntu),
configure the connection (host, auto-login with ssh key, choose to run Eclipse).
Everything is just as if I was working on a local machine, including building, debugging, and code indexing. And there are no noticeable lags.
I had the same problem 2 years ago and I solved it in the following way:
1) I build my projects with makefiles, not managed by eclipse
2) I use a SAMBA connection to edit the files inside Eclipse
3) Building the project:
Eclipse calles a "local" make with a makefile which opens a SSH connection
to the Linux Host. On the SSH command line you can give parameters which
are executed on the Linux host. I use for that parameter a makeit.sh shell script
which call the "real" make on the linux host.
The different targets for building you can give also by parameters from
the local makefile --> makeit.sh --> makefile on linux host.
The way I solved that one was:
For windows:
Export the 'workspace' directory from the Linux machine using samba.
Mount it locally in windows.
Run Eclipse, using the mounted 'workspace' directory as the eclipse workspace.
Import the project you want and work on it.
For Linux:
Mount the 'workspace' directory using sshfs
Run Eclipse.
Run Eclipse, using the mounted 'workspace' directory as the eclipse workspace.
Import the project you want and work on it.
In both cases you can either build and run through Eclipse, or build on the remote machine via ssh.
For this case you can use ptp eclipse https://eclipse.org/ptp/ for source browsing and building.
You can use this pluging to debug your application

How to edit in Eclipse locally, but use a git-based script I wrote (sync_git_repo_from_pc1_to_pc2.sh) to synchronize and build remotely
The script I wrote to do this is sync_git_repo_from_pc1_to_pc2.sh.
Readme: README_git-sync_repo_from_pc1_to_pc2.md
Update: see also this alternative/competitor: GitSync:
How to use Sublime over SSH
https://github.com/jachin/GitSync
This answer currently only applies to using two Linux computers [or maybe works on Mac too?--untested on Mac] (syncing from one to the other) because I wrote this synchronization script in bash. It is simply a wrapper around git, however, so feel free to take it and convert it into a cross-platform Python solution or something if you wish
This doesn't directly answer the OP's question, but it is so close I guarantee it will answer many other peoples' question who land on this page (mine included, actually, as I came here first before writing my own solution), so I'm posting it here anyway.
I want to:
develop code using a powerful IDE like Eclipse on a light-weight Linux computer, then
build that code via ssh on a different, more powerful Linux computer (from the command-line, NOT from inside Eclipse)
Let's call the first computer where I write the code "PC1" (Personal Computer 1), and the 2nd computer where I build the code "PC2". I need a tool to easily synchronize from PC1 to PC2. I tried rsync, but it was insanely slow for large repos and took tons of bandwidth and data.
So, how do I do it? What workflow should I use? If you have this question too, here's the workflow that I decided upon. I wrote a bash script to automate the process by using git to automatically push changes from PC1 to PC2 via a remote repository, such as github. So far it works very well and I'm very pleased with it. It is far far far faster than rsync, more trustworthy in my opinion because each PC maintains a functional git repo, and uses far less bandwidth to do the whole sync, so it's easily doable over a cell phone hot spot without using tons of your data.
Setup:
Install the script on PC1 (this solution assumes ~/bin is in your $PATH):
git clone https://github.com/ElectricRCAircraftGuy/eRCaGuy_dotfiles.git
cd eRCaGuy_dotfiles/useful_scripts
mkdir -p ~/bin
ln -s "${PWD}/sync_git_repo_from_pc1_to_pc2.sh" ~/bin/sync_git_repo_from_pc1_to_pc2
cd ..
cp -i .sync_git_repo ~/.sync_git_repo
Now edit the "~/.sync_git_repo" file you just copied above, and update its parameters to fit your case. Here are the parameters it contains:
# The git repo root directory on PC2 where you are syncing your files TO; this dir must *already exist*
# and you must have *already `git clone`d* a copy of your git repo into it!
# - Do NOT use variables such as `$HOME`. Be explicit instead. This is because the variable expansion will
# happen on the local machine when what we need is the variable expansion from the remote machine. Being
# explicit instead just avoids this problem.
PC2_GIT_REPO_TARGET_DIR="/home/gabriel/dev/eRCaGuy_dotfiles" # explicitly type this out; don't use variables
PC2_SSH_USERNAME="my_username" # explicitly type this out; don't use variables
PC2_SSH_HOST="my_hostname" # explicitly type this out; don't use variables
Git clone your repo you want to sync on both PC1 and PC2.
Ensure your ssh keys are all set up to be able to push and pull to the remote repo from both PC1 and PC2. Here's some helpful links:
https://help.github.com/en/github/authenticating-to-github/connecting-to-github-with-ssh
https://help.github.com/en/github/authenticating-to-github/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent
Ensure your ssh keys are all set up to ssh from PC1 to PC2.
Now cd into any directory within the git repo on PC1, and run:
sync_git_repo_from_pc1_to_pc2
That's it! About 30 seconds later everything will be magically synced from PC1 to PC2, and it will be printing output the whole time to tell you what it's doing and where it's doing it on your disk and on which computer. It's safe too, because it doesn't overwrite or delete anything that is uncommitted. It backs it up first instead! Read more below for how that works.
Here's the process this script uses (ie: what it's actually doing)
From PC1: It checks to see if any uncommitted changes are on PC1. If so, it commits them to a temporary commit on the current branch. It then force pushes them to a remote SYNC branch. Then it uncommits its temporary commit it just did on the local branch, then it puts the local git repo back to exactly how it was by staging any files that were previously staged at the time you called the script. Next, it rsyncs a copy of the script over to PC2, and does an ssh call to tell PC2 to run the script with a special option to just do PC2 stuff.
Here's what PC2 does: it cds into the repo, and checks to see if any local uncommitted changes exist. If so, it creates a new backup branch forked off of the current branch (sample name: my_branch_SYNC_BAK_20200220-0028hrs-15sec <-- notice that's YYYYMMDD-HHMMhrs--SSsec), and commits any uncommitted changes to that branch with a commit message such as DO BACKUP OF ALL UNCOMMITTED CHANGES ON PC2 (TARGET PC/BUILD MACHINE). Now, it checks out the SYNC branch, pulling it from the remote repository if it is not already on the local machine. Then, it fetches the latest changes on the remote repository, and does a hard reset to force the local SYNC repository to match the remote SYNC repository. You might call this a "hard pull". It is safe, however, because we already backed up any uncommitted changes we had locally on PC2, so nothing is lost!
That's it! You now have produced a perfect copy from PC1 to PC2 without even having to ensure clean working directories, as the script handled all of the automatic committing and stuff for you! It is fast and works very well on huge repositories. Now you have an easy mechanism to use any IDE of your choice on one machine while building or testing on another machine, easily, over a wifi hot spot from your cell phone if needed, even if the repository is dozens of gigabytes and you are time and resource-constrained.

How to do a "hard pull", as I call it: How do I force "git pull" to overwrite local files?

git repository sync between computers, when moving around?
My favorite editor, geany, has an option "Disk check timeout", after this timeout it checks if someone else has overwritten the file that I'm editing. This is a simple tool to detect if two people work on the same file (we don't use a version control system). Is there an option or a plugin for kdevelop that does the same thing?
Edit: as Zhigalin said KDevelop does the check automatically but only for local files, I need it for files opened using sftp.
In KDevelop this check is always active, you will get a popup as soon as you focus on that file in the editor.
Edit: if you are speaking of remote files than the reply is no, there is no such functionality.
So you have 4 options:
File a proposal here (which probably won't get implemented soon because of few active developers)
Patches are always welcome
[suggested] Start using a version control system like Git, there are even tools to automatically deploy on server when you make commit on a specific branch.
Use AutoFS(FUSE) to mount your server as a local folder.
Intro:
I have 2 folders which are on the same GIT repository, one is on a very slow Samba network drive, and one locally. using GIT on samba is extremely slow, but the Samba is my server, which is actually vmplayer running ubuntu server on a windows machine.
My question is:
is it possible to automatically copy files from the local directory, after a pull has been done, to the other samba folder. I do this in Sublime text editor (via addon), but it copies only when I save a file. I want that functionality also on GIT. (i'm mainly using TortoiseGit)
thanks.
Yes, there are git hooks. Have a look at
git help hooks
you can define what's automatically to be done after a pull. However, your system sounds insane and you should think about not doing that with the slow share. Also, I don't understand why an Ubuntu on a VMWare player would be really slow, unless you royally messed up configuration (not to mention I really don't understand why you wouldn't just let your windows do the shares, instead of letting a linux VM do that -- and I don't really like windows at all).
I'm working in a environment where files are at Windows side (because I like to work with phpStorm from that side) and Linux side (because I've a Virtual Machine running CentOS 6.6 and there is where LAMP environment is). The phpStorm project is a remote files one. This are the steps I followed to create the project:
Clone the repo at Windows directory
Copy the files to Linux using WinSCP
Create the remote project using phpStorm and this step copy the whole files from Linux to Windows.
I'm using SmartGit to manage my repos and do GIT/SVN tasks (the easy way). But surprise, files hasn't been changed but SmartGit says it does, but waits? How is that possible if the only steps I did was the one described above? Even if you try to open a file SmartGit will said that the content is the same? So, how to avoid this behavior? How to not to commit the whole files? If I made a commit already, how do I dismiss it? Is not the first time I'm running this problem but before repos was mine and I can lose every but now is a serious project and I take care for not damage others work. Any advice? Help? What you can do in this case?
See this pic:
There you can see what I'm talking about.
I have nearly identical Linux (Fedora) machines at home and at work and I keep my files on both machines synchronized using the excellent Unison program. I have been trying to keep an eclipse workspace synchronized across the two machines but this has failed. I tried both:
Synchronize just the /workspace directory, badness due to plugin upgrades
Synchronize both /workspace and my .eclipse/ director.
What happens is that I work in one machine, create new projects on eclipse, etc. Then unison. Then when I go to the other machine the projects will sometimes not appear, sometimes they will appear but eclipse cannot find the files, and sometimes (rarely) it works.
I don't understand why eclipse gets so confused since I have identical workspaces, eclipse versions, and even .eclipse directories.
Have considered going through a source control repository? If privacy is a concern, there are private SVN spaces available (e.g. assembla).
I understand this technique will (at least) make it possible to synchronize the projects but probably not all the settings related to a workspace. It might be an option, no?
Take a look at Pulse. It's an Eclipse distribution that can handle synchronization of workspace preferences across users and machines. It might be what you need.
I have been using dropbox to synchronize my workspace. I have been able to work on 3 different computers so far without any issues.
I used to store my workspace(s) and sometimes the eclipse installation itself on a USB stick drive and use that for project portability from windows machine to windows machine. You can then just run Eclipse from the stick and mount the workspace on the same stick.
I have also heard that drop box (http://getdropbox.com - they have a 2gb free plan) is useful for this, though I have not tried it.
It's odd that it does not work with your sync software.
I've ad issues with unison and eclipse and have them mostly worked out though it still needs to refresh the entire workspace when I switch systems.
There are two issues I've discovered that need to be configured before it is at all happy:
1) sync your workspace, your eclipse install and ~/.eclipse
2) Specify "ignorenot" rules in your unison "prf" files to not ignore any files in these directories. This is necessary because, by default, unison excludes files it thinks are built unsing rules similar to CVS which causes issues.
for example:
path = eclipse
path = workspace
path = .eclipse
ignorenot Regex eclipse/.*
ignorenot Regex workspace/.*
ignorenot Regex .eclipse/.*
Have you considered setting up a network drive and installing Eclipse on that drive (along with your workspace)? That way, when you open Eclipse on either machine, it will be pointing at the network path for your workspace. I've successfully used this solution in the past.
I used the Mercurial DVSC on a USB stick as the transfer between home and work. I had three Mercurial repositories: one on the USB stick, one at home and one at the office sharing the same space as my Subversion checkout. If you're up-to-speed with DVSC concepts, I'd push/pull changes from office->USB->home.
It worked fine, but the first check-in was a pain as USB flash writes have crappy speeds. Pushing/pulling deltas was fairly quick afterwords.
I believe the Mozilla guys use a similar hybrid approach of SVN for the 'official' repository, but the developers use Mercurial for their development environment.
