I followed the instructions on the Wiki exactly and keep getting the following error when building in Xcode.

Any ideas? Thanks

I seem to have fixed that issue by deleting and reinstalling my command line tools and rebuilding the xcode project

@atartanian Mind sharing what exactly did you delete, and how ?

#3

It didn’t work for me.

#4

Could you try to build after applying this diff https://developer.blender.org/D10838 ?
New build folder would be preferable.
