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:
* 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. * Do you have a new-enough c++ compiler. Since you're able to build a clang, that should take care of that issue. * Other libs you'll need. I needed to install these: yum install libedit-devel yum install python-devel yum install ncurses-devel yum install swig yum install libxml2-devel * cmake - you'll need cmake 2.8.12.2 or later. This one I'm pretty sure you're going to need to build this from scratch. * ninja - you're going to want to build the ninja build tool to optimize your build speed and use -GNinja with your cmake command line. It'll be interesting to hear what else you find. On Tue, Oct 27, 2015 at 8:37 PM, Mark Chandler via lldb-dev < lldb-dev@lists.llvm.org> wrote: > Using gcc 4.8 from devtoolset2.
