Re: [Dpcl-user] Unable to find libdwarf.so

[rajendra n. <raj...@ly...>]

Hi James,

Thanks a lot for the help. 
I was able to build the libdwarf libraries by getting the sources. The
compilation went through and I was trying to run the hello world program
given in the samples dir.

The analyis tool (eut_hello) was able to run the dpclSD and dpcld on the
remote host using rsh, but after the connection happened something seems
to be going wrong and the connection goes down and throws an error
"ASC_communication_failure" . Meanwhile the a.out program stops
execution. 
Am not able to comprehend whats going wrong. 
The dpcl Daemon is not dumping any core neither does it create a log
file in /tmp dir. ( which I guess means it has gracefully existed ). I
have enabled all the DEBUG options on the client as well as the daemon.
Below is the  log dump of the eut_hello prog..

It waits here for a couple of seconds and then
the connection goes down.
I checked the messages flowing between dpcld and the 
client( eut_hello). 
The eut_hello program seems to be sending the IP address of the mac where dpcld is running ( In this case
10.200.68.253) and then waits for some response from dpcld and upon not receiving anything times out

It would be of great help if you can give me a few hints on what might be causing the problem.

Thanks and Regards,
