Problems generating C++ classes under MacOS

Hopefully this isn’t a dumb question, but we’re trying to deploy UE4 for development on a small number of university computers. I was asked to look at the proposed build, and it mostly works ok - I can create a new project and add elements and blueprints. However, it won’t add C++ classes. When attempting to add one, both files are created in the folder on the HD, but it fails with the message “Failed to add class X. Failed to generate project files.”. Looking for hints online I’ve only found answers for Windows so far. In the log file, it appears to fail with a line saying that it can’t access “users/shared/…/IOS” (Wasn’t able to get the full path, but I can fetch it when next I have access to the test computer).

I’m assuming that it is a permissions issue. Can anyone confirm if this is the case?

Works for me without a problem.

There was previously (4.7.3) an issue with the prepackaged version that prevented the source code generation from working; the solution was to download the source and rebuild from scratch…

…but I believe 4.7.4 resolved that, and I haven’t seen any regression in 4.7.5.

Try building the editor from source and see if that fixes it. Obviously also your user account requires permission to run xcode.

They’re running 4.7.4, so that may not be the problem, then. I was hoping there were running 4.7.3 for an easy fix. I’ll see how I go with building the editor. Thanks!
