Problem building appleseed on LInux

[Rajiv Vaidyanathan]

When I built Appleseed on Linux, I got the following error:

Hey Rajiv,

It's interesting that none of the many compilers we're using has ever caught this. The code is mostly safe, but this compiler warning (turned compiler *error* since we enabled warnings-as-errors) is entirely legitimate.

Which compiler & version are you using?

As a quick fix to continue compilation, you can disable warnings-as-errors by running again CMake with -DWARNINGS_AS_ERRORS=OFF. In your build/ directory you can just do

    cmake -DWARNINGS_AS_ERRORS=OFF ..

    make

and that should get you going.

Thanks!

I pushed a fix to GitHub this afternoon.
