[Rock-dev] Ubuntu 16.04 xenial: orogen phase fails for base-orogen-std

[Thomas Roehr]

Hey Sylvain,

I am trying to build the debian packages for rock-core on Ubuntu 16.04,
but I am hitting the following error when building base-orogen-std.
As you mentioned you are using the toolchain on Ubuntu 16.04 already, I
might have missed something in the setup.

- LLVM 3.7 is in use
- TYPELIB_CXX_LOADER has been set to castxml

The error is the following:

There seem to be some related issues for LLVM 3.8
https://llvm.org/bugs/show_bug.cgi?id=27422,
https://llvm.org/bugs/show_bug.cgi?id=24872
However, how does your working setup looks like.
As a sidenote: I had to explicitely add /usr/share/llvm-3.7 to
CMAKE_PREFIX_PATH to get until this point?!

Best
Thomas
