For My Centos 5 build: * Using python 2.7 (From devtoolset 2)
* Using gcc 4.8 (From devtoolset 2) * disabled libedit and python bindings * Built cmake from source * Make is fine so didnt bother with ninja Applying the patch then gives me a working liblldb.so. Also want to say that its refreshing seeing such a good api. The interface is easy to understand and is standalone without pulling in a bunch of complex types from other libraries. Well done lldb team!

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.

Could you try to build LLDB with clang 3.5 specifying it via DCMAKE_C_COMPILER and DCMAKE_CXX_COMPILER flags? 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=..."

Looks like some features are used from newer kernel versions and was wondering what the procedure is to get this fixed and updated into lldb. These are the errors so far: https://gist.githubusercontent.com/lodle/47493c8ea2a51eff5322/raw/ce158e1d10d1df363bdd3a77b11ff3d8661e8144/lldb_make.txt Some of them are using O_CLOEXEC flag and headers that don't exist and was easy enough to add works around. The ones at the end im not sure about. Build Script: https://gist.github.com/lodle/e24a80907bbf7a7b72f6 Thanks for the help.
