Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Compilation error on MAC with UE4.8

Hi. I just upgraded to UE4.8.1 and I am getting the following errors when trying to compile in xcode.

 Ln: lib/mono/4.5/System.Reactive.Core.dll: File exists
 Ln: lib/mono/4.5/System.Reactive.Debugger.dll: File exists
 Ln: lib/mono/4.5/System.Reactive.Experimental.dll: File exists
 Ln: lib/mono/4.5/System.Reactive.Linq.dll: File exists
 Ln: lib/mono/4.5/System.Reactive.PlatformServices.dll: File exists
 Ln: lib/mono/4.5/System.Reactive.Providers.dll: File exists
 Ln: lib/mono/4.5/System.Reactive.Runtime.Remoting.dll: File exists
 Ln: lib/mono/4.5/System.Windows.Forms.DataVisualization.dll: File exists

I am able to start the engine fine but the above errors show up in the build log. Is there anyway to get rid of these?

Same with checking out 4.9.2-release on my Mac.

I still have the same error with v4.9. It runs even though there is a compilation error.

But it is blocking me from creating a new project. Any help on this?

Getting this in 4.15 on my branch. Don't think I saw it without branching.

Any clues on what I did wrong?
