[lldb-dev] unable to build lldb on linux

[Todd Fiala]

Hi Tiago,

Which version of Linux are you running under?  I assume it is Debian based
given the apt-get.

It looks like there might be a build error in top of tree based on your
output, I will check in a minute on my end.

I'll have a look at the packages listed in the docs to see if anything I
tend to need is missing.  I build pretty regularly both on Ubuntu 12.04
x86_64 and Ubuntu 13.10 x86_64, although I almost exclusively use gcc 4.8.1
or 4.8.2 due to some issues I ran into back in Nov 2013 (I need to work on
migrating or at least supporting clang in our build process).

Back in a bit after I see if I can get a clean build...
