PTP/environment setup 70

Setup for development of PTP 7.0

This is applicable to Kepler development for PTP.

  • Kepler-based development (June 2013 release) is on the ptp git repo master branch
  • Juno-based development (PTP 6.0.x) is on the ptp git repo ptp_6_0 branch

PTP now uses the git repository at and the CVS repository is now locked for writing.

Git reference info: Links to Git info

These instructions describe using the master branch of the repository. Please let us know (e.g. on ptp-dev mailing list) if these instructions need updating.

PTP 7.0 needs Java 1.6, Eclipse 4.2/Juno (eventually Eclipse 4.3/Kepler) , CDT supported by Kepler? (8.2?), and RSE 3.3 (?at least)

  • Download (Eclipse 4.3) here: "Eclipse Classic" is a good choice. Also because it is a SDK. An alternative is RCP. It already includes Egit&Mylyn.
    • Developing on a 4.2/Juno SDK will still probably work but we highly recommend using Kepler so we know our code works there.
    • Eclipse 3.x version have not been tested and we do not develop on them.

Install CDT, RSE, Git, etc. into Eclipse.

  1. In Eclipse, click Help > Install New Software...
  2. In the "Work with:" combo box, choose
  3. Under "Collaboration"
    1. "Eclipse EGit" (seems to be in default Eclipse Classic install now) - but if it's listed, meaning it's not installed - install it
    2. (Optional) Mylyn Task List, and Mylyn Tasks Connector: Bugzilla to track PTP bugs via Mylyn within Eclipse workbench
  4. Under "General Purpose Tools", check
    1. (Optional) "Parallel Tools Platform (PTP) End-User Runtime" - while you will probably check out source to override this, having it installed in the workbench can avert later build problems.
      • (presume outdated) Note: If you get a java.lang.ClassNotFoundException for org.eclipse.ptp.launch.ui.LaunchConfigurationTab in your target Eclipse install a recent build of this package (B. Watt 2013-02-07).
    2. "Remote System Explorer End-User Runtime" (RSE)
  5. Under "Programming Languages", check all of the following:
    1. "C/C++ Development Tools SDK"
    2. "Fortran Development Tools (Photran)"
    3. "Unified Parallel C (UPC) Support" (this includes CDT's LR parser)
    4. "XL C/C++ Compiler Support"
  6. (Optional) Under "Web, XML, JavaEE...", check
    1. "Eclipse Web Developer Tools" (useful for editing HTML files)
    2. "Eclipse XML Editors and Tools" (this is useful for editing XML files, e.g. creating resource manager configurations)
  7. Click the "Next >" button, click the "Next >" button, select accept agreement radio button and click the "Finish" button to complete the installation. Restart Eclipse when prompted.

JAXB shouldn't be needed to install, JAXB is now part of the Java 1.6 libraries

Set an API baseline.

In these steps, you will download the previous release of PTP. Eclipse's API Tooling will compare the current API with the API from the previous release to check for breaking changes.

  1. Download the PTP master archive of the previous major release of PTP. This will be a file named
    1. After June, 2012, this is
    2. After June 2013 Kepler release it will be PTP 7.0.0
  2. Unzip it into some directory (e.g. ptp-baseline-6.0.0)
  3. Open the Eclipse workbench preferences dialog. (On Windows or Linux, click Window > Preferences; on Mac OS X, click Eclipse > Preferences)
  4. Expand the "Plug-in Development" category, and choose "API Baselines"
  5. Click "Add Baseline..." In the dialog, enter "Default" for the name, choose the directory from step 2 for the location, click "Reset", and then click "Finish" to close the New API Baseline dialog.
  6. Click OK to close the Preferences dialog. (If a message dialog appears asking whether you want to perform a full build, click Yes.)

Checking out PTP projects

  1. File>Import ... then use the 'Git>Projects from Git' import wizard.
  2. Select "URI" and click Next >
  3. If you haven't yet cloned the repository to your machine:
    • Under Location: URI: enter the repository URI and click Next >:
    • Choose the branches you want to clone (usually ptp_6_0 and master==HEAD) and click Next >.
      • Note: all workspaces on your machine that talk to this local clone of the repository will all use the same branch at a time. You may want separate clones of the repo (one for each release/branch) for this reason. If so, the last page of the wizard lets you specify a different directory for this clone and you don't have to use same name as remote repo name for your directory.
        • One convention for this: Make two clones of the git repo, one for master (Kepler work) and one for the ptp_6_0 branch (Juno work). You can put both branches in each clone.
          • One set of suggested names of the repos:
          1. Set of repos where 'master' is the (default) branch used - for Kepler work (that is, name the repo to match the default branch -- or, just use the same name as the server repo)
            • org.eclipse.ptp-kepler
            • org.eclipse.photran-kepler
            • org.eclipse.ptp.master-kepler (this is the aggregated build project for eclipse hudson build server. Most developers won't need to clone this.)
          2. Set of repos where 'ptp_6_0' is the (default) branch used - for Juno work
            • org.eclipse.ptp-juno
            • org.eclipse.photran-juno
            • org.eclipse.ptp.master-juno (this is the aggregated build project for eclipse hudson build server. Most developers won't need to clone this.)
    • Click Next> to choose where you want the repository located locally. It can be anywhere. See suggested names above if you don't have a better idea.
      • Also choose what you want the default branch to be (if other than master)
    • Click Finish. The repository should be downloaded.
    • Once the repository has downloaded you should see it in the list. Select it.
  4. If you have already cloned the repository, and it isn't shown in the list (e.g. Clone done from another workspace)
    • Select Add... and add it.
    • You should now see it in the list. Select it.
  5. Click Next> then Next> again and you should see a list of all the projects.
  6. Select all of the projects except the following (omitting them is optional; you can also just close then later if you like, or just ignore errors), then click Finish. (The tests projects are unit tests for RDT; to compile and run them, you would need to check out the source code for CDT's unit testing projects and their dependencies. Omitting them just keeps confusing build errors out of your way.)
    • org.eclipse.ptp.rdt.core.tests
    • org.eclipse.ptp.rdt.ui.tests
    • org.eclipse.ptp.rdt.sync.rsync.core
    • org.eclipse.ptp.rdt.sync.rsync.ui

Repeat the steps to import another repository (e.g. Photran).

It is also necessary to set Git options to ensure that updates are done correctly.

ONCE ONLY: (Git settings are saved on disk, so shared across workspaces and Eclipse installations.)

  • Open Window>Preferences>Team>Git>Configuration
  • Select the "User Settings" tab
  • Click "Add Entry"
  • For "Key", enter branch.autosetuprebase
  • For "Value", enter always
  • Click "OK"


  • Open Window>Preferences>Team>Git>Configuration if it's not already open
  • Select the "Repository Settings" tab
  • Select the repository from the "Repository" dropdown
  • Click "Add Entry"
  • For "Key", enter branch.master.rebase
  • For "Value", enter true
  • Click "OK"
  • If you are working on the ptp_6_0 branch (or other branches)
    • Do the same thing, but use key branch.ptp_X_Y.rebase

Build internal PTP parts

The first time, or if changes occur in org.eclipse.ptp.lml.da.server:

  • In project org.eclipse.ptp.rm.lml.da.server, create a new lml-driver.tar by right clicking on build.xml and selecting Run As > Ant Build


Updating existing projects

  • Right-click on a project and use Team>Pull - this updates the existing projects in your entire local repository, and the current branch in your workspace

Platform Git workflows wiki page has more detail here (including splitting Pull into its two actual steps of Fetch and Merge]


  • Make sure you have set branch.autosetuprebase=always and branch.<name>.rebase=true as described above
  • This causes a Pull (analogous to a 'cvs update') to do the following:
    • Fetch
    • Rebase (It undoes all local commits, fast-forwards the local version to the remote one, and then reapplies the local commits)
  • Otherwise a Pull only does a Fetch/Merge which causes a spaghetti like history

If new projects have been added to the repository,

  • Do an Import ... Git > Projects from Git, Next, Choose 'Local', Next, Choose your repository, Next, Next (leave default for 'Import existing projects' and working directory), and on the 'Import Projects' page you should see all the existing projects greyed out, since you already have them in your workspace; make sure all the new projects are checked and hit 'Finish'.

Committing to remote repository

There are two steps to getting code changes in the remote repository at commit then push. (This was a single commit step in CVS. Eclipse Kepler's EGit allows this in a single step via a "Commit and Push" button as well.)

  1. Pull to get the latest changes and prevent errors when you push
    • right-click on any project in the repository and use Team>Pull
  2. Commit to your local repository - this can be on single files or groups/whole project
    • right-click on your project and use Team>Commit
    • If there is a associated bugzilla - copy and paste the title, for example, Bug 400832 - Fix attribute from MP_CC_BUF_ATTR to MP_CC_BUF_MEM_ATTR
  3. Push to copy it to the remote repository - do it on project, e.g. from Project Explorer; all commits in your local repository (including other projects) get pushed up to
    • right-click on any project in the repository and use Team>Push to Upstream

Alternatively, you can

  1. Team>Pull (on any project in the repo) first to make sure you've updated, then
  2. Team>Commit and use the checkbox to 'Push the changes to upstream' at the bottom of the 'Commit Changes' dialog.

Platform Git workflows wiki page is helpful here.

Here are the steps:

  • If there is an associated bugzilla for the change, then assigned to yourself that is "take" the Bugzilla.
  • Checkout the branch you want to commit changes, for example local:master -> remote:master
  • If it is already checked out, Pull to make sure it is in sync
  • Make changes / Apply patch
  • Commit. Specify Bugzilla if available, and specify Author - contributor of the patch, and yourself as Committer.
  • Push.
    • If push failed, you may not be having latest version. Rerun pull.
  • If there is an associated bugzilla for the change, then mark the Bugzilla RESOLVED - FIXED. Note: The bugzilla is marked verified/closed after the release.

In history view you should see

[master][origin/master][HEAD] Bug xxx - your fix

API baseline and code formatter

Building runtime binary

(This is only true of the older resource managers that require a proxy on the target machine. Not needed for most recent resource managers now.)

To e.g. run with a resource manager, you may have to build some platform-specific binary/proxy code. For example, to run with OpenMPI locally on MACOSX, cd to the org.eclipse.ptp.macosx.x86 project in a terminal window, and execute

  • sh BUILD

This should build the executable 'sdm' in the bin/ directory. Do not be alarmed if you see "LoadLeveler not installed, skipping..." etc - if you do not have these IBM components installed on your system, there is no need for it to build those binaries.

Copy Remote Tools Dstore server jar

If you are using Remote Tools ... you may see the error "Unable to locate payload "rdt-server.jar" in bundle "org.eclipse.ptp.rdt.server.dstore" " when you launch a runtime workspace and make a (purely) remote project.

So you must do the following (Until we can build rdt server jar here) ... From a PTP (end-user) installation, unzip eclipse/plugins/org.eclipse.ptp.rdt.server.dstore_xxx.jar into a directory. Then from the unzipped contents move rdt-server.jar to your development workspace project: org.eclipse.ptp.rdt.server.dstore

(This is the file that will be moved up to the remote host location when you create a remote project. Remote Tools installs this jar on the server automatically and starts it for you.)

If you don't, you will see the error popup "Unable to locate payload "rdt-server.jar" in bundle "org.eclipse.ptp.rdt.server.dstore"

Copy LML Driver tar file

If you are developing PTP from source in your development workspace and launching into a runtime workspace you also get a similar error to the one above:

"Unable to locate payload "lml-driver.tar" in bundle "org.eclipse.ptp.rm.lml.da.server""

TO fix this, install PTP e.g. from ptp-master-xxx or parallel package, and copy this tar file from the eclipse/plugins dir jar file, into the same-name project in your dev workspace. e.g. from eclipse/plugins/org.eclipse.ptp.rm.lml.da.server_xxx-yyy.jar - unzip that jar file, to find lml-driver.tar and copy that to the plugin project org.eclipse.ptp.rm.lml.da.server

Launching a runtime workbench running the code you checked out into your workspace

  1. Run > Debug Configurations ...
  2. Double-click on 'Eclipse Application' - or click and click on the 'new' icon
  3. Defaults are probably ok to run with all the plugin projects in your workspace; hit 'Debug' in lower right corner

Compiling XML Schema (XSD) into Java classes using the JAXB compiler (xjc)

Should there be a need to alter the provided schemas for the JAXB Resource Manager (or any other such JAXB tooling), follow these steps to set up compilation:

  1. Download jaxb-ri (xjc); e.g., from JAXB Project (Note: Mac OS X already has xjc installed)
  2. Install it somewhere on your local machine
  3. In your project workspace, create an External Tools Configuration. The following is an example based on org.eclipse.ptp.rm.jaxb.core, which has the .xsd in the data directory:
    1. Location: {jaxb-ri directory}/bin/ or /usr/bin/xjc
    2. Working Directory: ${workspace_loc:/org.eclipse.ptp.rm.jaxb.core}
    3. Arguments: data/resource_manager_type.xsd -p -d src

Each time you run this, all the source files generated from the schema will be overwritten.
