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

[Dave Wootton <dwootton@xxxxxxxxxx>]

I think I have sort of figured out how
I'm getting a path of '\usr\include' but I don't know why. I did create
a remote C project using the project wizard. If I look at the 'Remote Paths
and Includes' page in the project properties, it's pre-filled in with '/usr/include'.
I added an entry for '/usr/include/sys' in this page, and now I get two
error messages for invalid project path, one for \usr\include and a second
for \usr\include\sys. It looks like something is getting confused about
Linux/Unix path separators and Windows path separators and using the windows
path separator '\' since my Eclipse installation is running on a windows
XP system. I grepped thru the PTP source I downloaded looking for any reference
to path.separator or file.separator properties as well as looking just
for separator and didn't find anything. Could there be code that knows
it's running on Windows and just hard codes '\' as the path separator?

If I clean my remote project, then when
it rebuilds, I get two error messages 'Error launching external scanner
info generator (/opt/ibmcmp/xlc -E -v F:/source/runtime-New_configuration/.metadata/.plugins/org.eclipse.cdt.make.core/specs.cpp)'.
I'm not quite sure where this is coming from, but wanted to point this
out as well.

Neither of these are serious problems
for me since I'm interested in getting my PE proxy working with remote
projects and I can create a remote project that I can use with my proxy.
I have to compile my test programs by hand on my Linux system so I can
run them, but that's not a big deal right now.

Dave,

Not sure about 1 or 2 (maybe Chris can help?). It's possible RSE is  
not working with PTP as I've been concentrating on remote tools. I'll  
take a look and see if I can repeat the problem. Can you tell if the  
proxy is getting started at all? Is the path to the proxy correct?  
Output from the process should go to a console if you have the  
"Display combined output in a console view" option set in the
launch  
configuration. You should also still be able to use the old jobs view  
to double click on a process icon. Not sure why you're not seeing  
processes though. I'll take a look at that as well.
