[lldb-dev] Errors generated when building lldb in Ubuntu 12.04

[Bo Zheng]

Hi everyone,I tried to build lldb following the instructions provided on
the build instruction section <http://lldb.llvm.org/build.html>, but I got
these errors when making lldb. I now really donot know what to do or how to
fix them. If anyone suffered the same issue ever or knows how to fix these
errors, please let me konw.
Thank you.
