[Bf-cycles] Issues on building cycles standalone with OSL

[lorenzo angeli]

Hi all,
I'm trying to get cycles standalone built with OSL, but I'm having some
problems.

I tried first with blender/build_files/build_environment/install_deps.sh
--with-osl
But this resulted in this error :

I then tried to rely on the system libraries (I'm on mint 17).
(osl version is 1.4.2 )

But it fails during the compilation with :

/home/efesto/SRC/cycles/src/kernel/osl/osl_closures.cpp: In function ‘void
ccl::register_closure(OSL::ShadingSystem*, const char*, int,
OSL::ClosureParam*, OSL::PrepareClosureFunc)’:
