required arnold and mtoa versions

[Est]

Hi all,

I'm currently trying to build Cortex with Arnold support, 

using arnold 4.2.11.0 and mtoa 1.2.6.1.

It seems IECoreArnold builds, but when the mtoa translator is built 

I have this error:

Is there a specific mtoa version that I should use?

Thanks!

To be blunt, I have no idea. Although I still work on IECoreArnold to support Arnold in Gaffer, it has been a very long time since I built the MtoA extension, and the MtoA API seemed to be a bit of a moving target back then. We'd be more than happy to receive a pull request with updates for a recent MtoA version, but I think at this point it's unlikely to be something that originates from one of the core team (Arnold support is in contrib after all)...

Cheers...

John

Hi,

I built everything else without problems. I'm not sure we need the translator.

I'm going to ask and if we need it, I'm going to try to update it and send a PR.

Thanks!

Est.
