[Bf-committers] Cycles incompatibilities with latest OSL master

Hi Devs,

I spent the day updating install_deps.sh to oiio 1.3.9 & osl 1.4.0…

As I was tired of our ugly patches inside this script, I decided to move 
back to custom git fork of the projects, with needed fixes (and pull 
requests! :P ), thus I had to use HEAD of oiio and osl instead of the 

Finally got everything working (with even updates for latest OpenEXR 
2.1.0, which changes its libs names, grrr), but current cycle code has 
one issue: in cycles/render/osl.cpp, OSL::ShadingSystem 
*ss->clear_state() exists no more.

I managed to compile by simply commenting those four calls, and from a 
very quick test it seems to work, but not sure this is a correct 
solution… So it would be great if our Cycles experts could check this… ;)

Best regards,
