<div dir="ltr">I fixed several RHEL-derived distribution-related issues in top of tree LLDB a few weeks back. It was for RHEL 7-derived builds, so quite a bit newer. If you are building your lldb off of top-of-tree, hopefully this will mostly become an exercise of:<div><br></div><div>* Do you have a new-enough python. (I believe at this point you really want a 2.7, but with CentOS 5 you might be far back enough to be 2.4 or 2.6. We probably limp along with 2.6 since that was our baseline for a while). Worst case here you can download a newer python and build from source, then specify it to cmake via the right python cmake variables.</div><div><br></div><div>* Do you have a new-enough c++ compiler. Since you're able to build a clang, that should take care of that issue.</div><div><br></div><div>* Other libs you'll need.

</div>
<div>what compiler do you use? Could you try to build LLDB with clang 3.5 specifying it via DCMAKE_C_COMPILER and DCMAKE_CXX_COMPILER flags?</div>
<div>It might be a problem with sysroot setup since some headers are not found - you can try to pass a custom sysroot with -DCMAKE_CXX_FLAGS="--sysroot=..."</div>
