Dear all,
I am trying to build latest lldb from svn. After created the lldb_codesign
certificate following code-signing.txt, I built lldb on lion by Xcode 4.2.1
with no problem. But when I try to build it on a Mac which running snow
leopard (10.6.8) by Xcode 4.2, building failed with an error in lldb-platform:

I know the linker can not find the symbols "___pthread_fchdir" &
"___pthread_chdir". I try to set the link flag "-lpthread", but it's
helpless. And it seems thread model is already set to posix.
Which library exactly should be linking against?
Thanks,
Hank
