<div dir="ltr">Hi All<div><br></div><div>Thanks a lot for all the inputs. </div><div><br></div><div>@Greg: I could make it work using the lldb-platform. I had checked out source code of LLDB on Feb 16 and had built (Debug+Asserts) it on Fedora 20 system (x86_64). I will like to make few comments which are inlined. </div><div><br></div><div>@Vince: Are you building LLDB for x86_32 Linux ? I tried to build it (Debug build) for such a system and it fails during linking process because of lack of memory. </div><div>In order to bring up x86_32 support, are you following a different approach ?

<br>
On the remote machine launch lldb-server:<br></blockquote></div></div></div></div></blockquote><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex"><div class="gmail_extra"><div><div class="h5"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex">
<a href="http://remote.foo.com" target="_blank">remote.foo.com</a>% lldb-server platform --listen=2000 --stay-alive<br>
<br></blockquote></div></div></div></div></blockquote><div><br></div><div>I had to replace "lldb-server platform" by "lldb-platform" because right now, building lldb doesn't generate any binary with name lldb-server.</div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex"><div class="gmail_extra"><div><div class="h5"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex">
Then on your host machine:<br>
<br>
<a href="http://host.bar.com" target="_blank">host.bar.com</a>% lldb<br>
(lldb) platform select remote-linux<br>
(lldb) platform connect connect://<a href="http://remote.foo.com:2000" target="_blank">remote.foo.com:2000</a><br>
<br>
Now you have a live connection to a platform server on the remote host so you can list existing processes:<br>
<br>
(lldb) platform process list<br>
(lldb) platform process attach --pid ...<br>
<br>
Or you can launch:<br>
<br>
(lldb) file /path/to/binary<br>
(lldb) process launch -- arg1 arg2<br>
<br>
The platform will launch a lldb-server to debug your programs on the other system.<br><br></blockquote></div></div></div></div></blockquote><div><br></div><div>This thing worked pretty well.</div><div> <br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex"><div class="gmail_extra"><div><div class="h5"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex">
<br>
<br>
The other is to just directly debug a process. In this case we don't go through the platform, we just start lldb-server on<br>
<br>
<a href="http://remote.foo.com" target="_blank">remote.foo.com</a>% lldb-server gdbserver <a href="http://host.bar.com:2000" target="_blank">host.bar.com:2000</a> -- arg1 arg2<br>
<br></blockquote></div></div></div></div></blockquote><div> </div><div>Again , I replaced "lldb-server gdbserver" by lldb-gdbserver.</div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex"><div class="gmail_extra"><div><div class="h5"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex">
Then attach to it:<br>
<br>
<a href="http://host.bar.com" target="_blank">host.bar.com</a>% lldb<br>
(lldb) file /path/to/binary<br>
(lldb) process connect connect://<a href="http://remote.foo.com:2000" target="_blank">remote.foo.com:2000</a><br>
<br></blockquote></div></div></div></div></blockquote><div><br></div><div>While running process connect command, I got the following error</div><div> "error: remote connections are not supported"</div><div><br></div><div> <br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex"><div class="gmail_extra"><div><div class="h5"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex">
Now you will be stopped at the program entry point and ready to debug a single process.<br>
<br>
All of this is of course using the top of tree SVN sources. It will change a bit if you are using older sources.<br></blockquote></div></div></div></div></blockquote><div><br></div><div>The above error might be because my source code is old. But I am not sure given that the source code is 9 days old.<br></div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex"><div class="gmail_extra"><div><div class="h5"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex">
