[panda-users] Compilation issue

[Fabien Dombard]

Hi Brendan,

$ dpkg -l | grep -i llvm
ii  libc++-dev:amd64                      3.5-2                                amd64        LLVM C++ Standard library (development files)
ii  libc++-helpers                        3.5-2                                all          LLVM C++ Standard library - build helpers
ii  libc++1:amd64                         3.5-2                                amd64        LLVM C++ Standard library

I've compiled locally llvm 3.3 as per the instructions found within the docs/compile.md.
I also been checking the panda_install.bash and have all necessary dependencies, it fails on the build.sh step.
Thanks,
Fabien
