Randy,
PTP 3.0 isn't "released" yet, we're still working on it. But many folks, like you, are using it to get the latest features and give us feedback.
So the info isn't on the doc page you mentioned. It will be when it's "released"
In fact, the user documentation hasn't been updated for 3.0 yet so there's nothing new to put on that page.

PTP 3.0 requires at least CDT 6.0.1
6.0.1 is now "released" as part of Galileo SR1
You're probably looking at the CDT builds page and builds are done frequently for the next release as well (which will be 6.0.2)
So, 6.0.2 should work, but 6.0.1 has been tested more.

The Eclipse C/C++ IDE (from the Galileo SR1 download site: eclipse.org/downloads) uses the latest released version of CDT, which is 6.0.1
(altho there is a problem with how the versions are shown within that download. If the versions show e.g. 6.x.x.20090911xxxx, it's part of 6.0.1 - make sure it's got 20090911)

Probably more info than you wanted, but there!

Beth,

OK, thanks for the update.  I'm getting back to a stable 3.5 (after re-installing all my pkgs - C++, svn,Pydev).  I'm still curious where Eclipse buries its session info, but won't lose sleep over it.

Fwiw, there's also a CDT 6.0.2 available (which I downloaded), so I wonder if you should just say "6.0.x" on the wiki (and perhaps mention "6.1.x" is for Eclipse 3.6).  And I'm wondering which version of CDT is used for the Eclipse/C++ IDE and whether or not that matters for PTP 3.0.

Also, it seems like you'd want a link to PTP 3.x on this page:  http://eclipse.org/ptp/doc.php

Randy,
I've been updating the Release notes this morning, so please reload.
Among other things, I specifically changed the "We recommend Eclipse Classic" to also include the Eclipse/C++ IDE.

You can have multiple Eclipse installations, and multiple workspaces, on your machine.
There is no need to delete one to try another. (You don't want to know how many I have on my machine.)
Just unzip/untar eclipse in a different directory.

I don't know what's happening as you describe below, but it sounds like you're still using the original workspace? Hard to tell without being there.
Follow the release notes for 3.0, and let me know if there are problems.
(Refresh occasionally, I may change more this afternoon based on some testing we are doing today.)
Your input is welcome to help us make our installation instructions better!

I've decided to start from scratch on this little project. Previously, I'd installed the Eclipse/C++ IDE (thinking that would be the logical approach for playing with PTP). Now, I'm following the Release Notes for PTP 3.0 (http://wiki.eclipse.org/PTP/release_notes/3.0) and decided to follow the advice of "We recommend Eclipse Classic". So I removed my old Eclipse/C++ installation, removed my entire workspace associated with that installation, installed Eclipse Classic (SDK 3.5.1), start it up and it attempts to open all previous files I was editing (they appears in tabs across the top), but complains that it cannot open the editor - no editor descriptor for id org.eclipse.cdt.ui.editor.CEditor

My question is - and I realize it's off-topic for this PTP list, where/how is eclipse picking up my previous session, given that I deleted most of its brains?

I confess that I also have a previous version of Eclipse (3.4.2) installed, but it points to a different workspace.

thanks, Randy

Hi Randy,

You need to do the following:

1. Select (or enter) the path to the application executable in the "Application program" field in the "Application" tab.

2. Select SDM from the dropdown on the debugger tab.

3. Enter "/bin/ls" (or the path the the sdm executable if you have it) in the "Path to debugger executable" field on the debugger tab.

At this point the Run button should be enabled. The program will only run when you click this button.

Note that in general you won't be able to run the application while you still have errors (little red X's) in the launch configuration.

Hope this helps,

Greg

Greg,

Thanks for the reply. I'm still confused when you say I don't need SDM. It seems that if I don't do *something* for the Debug panel, I can never enable the Run button. Fwiw, I've decided to keep a running visual log of my approach here:

http://mypage.iu.edu/~heiland/ptp/

For the time being, I guess I'll go off and read about SDM.

Randy,

You don't need to install RDT. That is only required if you want to
host your project (i.e. the source code) on a remote machine.

You don't need the SDM debugger to just run your application, however
the launch configuration currently requires an executable before it
will let you run the application. You can pick anything as long as
it's an executable (e.g. /bin/ls). Instructions for building the SDM
are in the release notes in case you actually want to use it.

You won't see anything in the machines view until you actually run the
application (by clicking the run button on the launch configuration)
and you can't do that while it's reporting an error. The above should
get you going though.

Regards,
Greg

Hello,

I'm trying to install/test a simple PTP 'hello world' example just
on my laptop, no client-server. My environment is:

OSX (10.5)
Open MPI 1.3.3
Eclipse 3.5
Version: 3.5.0.v20090611a-9gEeG1HFtQcmRThO4O3aR_fqSMvJR2sJ
Build id: I20090611-1540
PTP Version: 3.0.0.200908291618


First naive question - do I need to install RDT in order to do this?

I've got to the point of creating a MPI 'hello world' C++ pgm and
then try to follow the "Test your installation" section in http://wiki.eclipse.org/PTP/release_notes/3.0

Second naive question - do I need the SDM debugger to be able to
successfully setup my Run Configurations? I'm not familiar with SDM
and would welcome pointers. I guess I never completely fill in the
Run Configs panel due to the missing SDM (the Debugger tab remains
"red-X'd") and therefore the "Run" button is never enabled - I can
only Close the panel. Even though I set # of procs=2 on the
Resources tab (and then Close the panel), I never see 2 nodes appear
in the "Machines" tab of the PTP Runtime perspective.

thanks for any help,
-Randy
