Just an update that I issued a [PR](https://github.com/SuperElastix/elastix/pull/128) to Elastix to fix the remaining build errors. Once this is integrated I’ll update the hash.

This is great, thank you! Until they integrate the fix, you can fork the Elastix repository and use that fork for nightly builds. It would allow us to start testing Elastix build on all operating systems.

Looks like there’s a small conflict between @cpinter’s patch and the one @N-Dekker did. If it doesn’t get resolved in a few days then yes, doing temporary Slicer-specific elastix fork would be a good idea.
