You need to build against OpenImage 1.4 or higher, it seems you are using version 1.3. I guess that means building it yourself or getting a newer package from e.g. here:
https://launchpad.net/ubuntu/+source/openimageio

[unicomp21]

I get exceptions when adding the ppa. Building it myself sends me down the rabbit hole with openexr, etc.

[unicomp21]

I'd love to get this puppy building on Linux. I realize it works in Blender as a renderer, but I want to use OSL directly thru it's command line tools, etc.

[brechtvl]

Ok, if installing the ubuntu package for OIIO doesn't work, then either you'll have to build OIIO 1.4 or newer manually first, or use an older OSL version.

[unicomp21]

I tried building the latest OIIO, and it ends up with broken deps on ilm
components.

I'd love to be able to use the latest version.

Is there a OSL developer I can get in contact with to fix building on Ubuntu/Debian? There are multiple problems on 15.10. Should not be too hard to fix this properly.

[lgritz]

I think this would be a good question to ask on the osl-dev mail list, which has a much wider audience than those who monitor the GitHub "issues".

I, unfortunately, don't have easy access to an Ubuntu/Debian machine, so this isn't something I can reliably work out myself, except in cases where I just happen to be able to diagnose the likely problem by looking at the build logs.

[lgritz]

Closing, this references a very old version. Make a new issue if it's still a problem with modern OSL.
