[lldb-dev] Fail to compile LLDB 3.4

[Todd Fiala]

Hi Jun,

We've been using the following setup:

Ubuntu 12.04
gcc 4.8.2
latest libedit from here <http://thrysoee.dk/editline/>

We make sure we modify our LD_LIBRARY_PATH to include the gcc 4.8.2's
libstdc++ (needed to solve the issue of having an old libstdc++ in Ubuntu
12.04) and the newer libedit.  Technically I don't think you'll need the
new libedit until the iohandler branch gets merged into trunk, but you'll
likely need it at some point if you're on a similar setup to us and if you
build from top of tree.

I had played around with several options to get lldb built with clang on
Ubuntu 12.04 x86_64 a couple months ago but gave up due to errors on each
of several different approaches (using a clang bootstrapped with gcc 4.8.x,
using a clang from the official llvm.org precise build, using a clang with
a built libc++, etc.)  At some point I'll get back to looking at those
combinations, but for now the gcc 4.8.2 path works well for us.

Hope that helps!

-Todd
