[ptp-dev] Questions about PTP, RSE and RDT

[Dave Wootton <dwootton@xxxxxxxxxx>]

I installed Ganymede Eclipse plus CDT 5.0.1, RSE 3.0.0 (core and end user 
runtime) and then downloaded PTP and RDT code into my workspace from PTP 
HEAD, all on a Windows XP machine. I'm able to create a C project running 
Eclipse on my windows machine where the project is located on a pSeries 
Linux system. I can't get the compilation to work thru Eclipse, but if I 
compile my test program manually, I can then create a PTP run 
configuration referencing that project and run my test application thru 
PTP. So my PE proxy pretty much works with the current PTP code.

I did have some problems doing this and have the following questions
1) When I created my C project (Executable (XL C/C++)), the last page of 
the project wizard asks me for the compiler root path, where it is 
pre-filled in with /opt/ibmcmp. I have XLC 9.0 installed in 
/opt/ibmcmp/vac/9.0. What do I specify for compiler root path?
2) I can edit .c files on the remote Linux system using the Eclipse 
editor. When I save the file, the build fails, I suspect because of the 
message 'Invalid project path: Include path not found (\usr\include)' 
(note backslashes in pathname). I looked thru the project properties 
panels and couldn't find where I specified this so that I could fix it.
3) I can create a PE resource manager using RSE as the remote service 
provider, and as I go thru the resource manager wizard, it appears to work 
correctly, letting me set the path to my proxy on the remote system. 
However, when I try to start the resource manager, I get a popup htat says 
'Failed to start resource manager' and the RM icon turns blue and stays 
that way. I turned on tracing in the run configuration for my test session 
and don't see any obvious messages in the trace output. It looks like it 
gets as far as trying to invoke my proxy, but then stops. I have an option 
in my proxy where I can put it in a spin loop at startup so I can attach a 
debugger to it. I turned that option on so I could try to attach to my 
proxy and it appears Eclipse is not getting far enough to invoke my proxy 
since I still cannot find the process. The same proxy works fine if I use 
RDT as the remote service provider. Any ideas where to start looking? Has 
RSE 3.0 broken something in PTP?
4) My program appears in the jobs list, but I don't see any way to either 
get the job to show me stdout output or to delete the job from the jobs 
list when it completes. My program does write stdio, which I can see if I 
set up my test program's run configuration to redirect stdout to a file.
5) When my program runs (2 tasks on 1 node) , I see the icon for the node 
I use show up in the machines view, but neither process shows up in the 
process info window. What messages generate the data for the process info 
window. I need to see if my proxy is generating correct messages as a 
first step in figuring this out.
