Hello, A few members of our team who work on Mac machines are having issues launching the project which is a C++ and Blueprint built project.

Our files are transferred and obtained using perforce, after these users obtain the source files from perforce they are unable to properly launch the project. This includes when trying to after installing XCode and rebuilding the project with XCode.

Bellow is some documentation on the issue :

  1. Upon first trying to open the uproject file by double-clicking, this message appears:

  1. After selecting YES (to rebuild), it attempts to automatically rebuild but fails and opens this message:

  1. At this stage, we were instructed to download Xcode, right-click on the project file and select “Generate Xcode project”. This message appeared:

  1. After some research, We discovered that in order for the Xcode project to generate, a folder titled “Source” needed to be created and placed in the project folder. See picture:

  1. After adding the “Source” folder, we attempted to Generate the Xcode project once again. The code begins to generate, but it reaches an error and says this:

  1. If the project is opened using Xcode, this happens:

  1. If we attempt to open the UE4.xcodeproj located in Faceless/Intermediate/ProjectFiles, Xcode opens and begins to process the file. After what is says is “pre-indexing” for a while, it says it is ready. The folders you see on the left side of the picture contain lots of files (.usf, .ini, .uplugin etc).

Even after this process in Xcode, the same error codes come up when an attempt to open the project is made.

Sorry for the long winded post, If anyone can help it will be greatly appreciated.

Hi ENP,

I am a little concerned about a detail you mentioned in your post. You stated that your project includes both C++ and Blueprints, but when you transferred the project through Perforce to the Mac, it no longer had a Source folder? The Source folder is where all of the C++ for your project would be located, and if this folder is missing then I would expect Xcode to have some of the problems that you mentioned. Adding an empty Source folder wouldn’t help in this instance.

Would you be able to verify that the Source folder did not actually make it to the Mac you are having this problem on? If that is the case, could you try doing a force sync in Perforce to get that folder added to your project on the Mac?

Thank you for your answer, this was indeed the issue (the source folder not correctly being pulled from our perforce server).

Now that this has been identified the issue has been resolved.

Thank you again.
