<div>Ah, I see, I was using Xcode 4.3.3 but Xcode 4.5.1 does have the lldb version with core support document. Thanks for your help!</div>

Great, thanks Greg. I must not have the most up-to-date lldb version, for I see the following when I do the same commands:
<div><br>
</div>
<div>
<div>(lldb) version</div>
<div>LLDB-112.2</div>
</div>
<div>
<div>(lldb) apropos core</div>
<div>No commands found pertaining to 'core'. Try 'help' to see a complete list of debugger commands.</div>
<div>
<div>(lldb) help target create</div>
<div> Create a target using the argument as the main executable.</div>

<div> Specify the initial SDK build number.</div>
<div><br>
</div>

<blockquote type="cite">I have a question regarding debugging a core file. With gdb, one can specify -c <core_file> to debug a core file. However, I can find no documentation to do this with lldb. Is there such a way? lldb seems to think the core file is an
executable, which isn't necessarily what I would like. Any suggestions?<br>

(lldb) apropos core<br>
The following commands may relate to 'core':<br>
target create -- Create a target using the argument as the main executable.<br>
(lldb) help target create<br>
Create a target using the argument as the main executable.<br>
<br>
Syntax: target create <cmd-options> <filename><br>
<br>
Command Options Usage:<br>
target create [-a <arch>] [-p <platform-name>] [-v <none>] [-b <none>] [-s <filename>] [-c <path>] <filename><br>
<br>
-a <arch> ( --arch <arch> )<br>
Specify the architecture for the target.<br>
<br>
-b ( --build )<br>
Specify the initial SDK build number.<br>
<br>
-c <path> ( --core <path> )<br>
Fullpath to a core file to use for this target.<br>
<br>
-p <platform-name> ( --platform <platform-name> )<br>
Specify name of the platform to use for this target, creating the platform if necessary.<br>
<br>
-s <filename> ( --sysroot <filename> )<br>
Specify the SDK root directory that contains a root of all remote system files.<br>
<br>
-v ( --version )<br>
Specify the initial SDK version to use prior to connecting.<br>
<br>
This command takes options and arguments, if your arguments look like option specifiers you must use '--' to terminate the options before starting to give the arguments.<br>
<br>
<br>
<br>
So there is documentation.<br>
<br>
(lldb) target create --core /cores/core.1235<br>
<br>
You can optionally give us the architecture and/or executable file if you know them:<br>
<br>
(lldb) target create --core /cores/core.1235 --arch x86_64 /path/to/executable<br>
<br>
After this commend, you can then do a:<br>
<br>
(lldb) thread list<br>
(lldb) thread backtrace all<br>
<br>
Core files only work for mach-o core files right now. ELF support hasn't been done yet, but there is good sample code to follow in the following directory:<br>
<br>
lldb/source/Plugins/Process/mach-core<br>
