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"

Linker warnings on OSX 4.11 preview 3

Getting these warnings when compiling from source. Running XCode 7.2 on El Capitan. UBT indicates I'm compiling with Mac SDK 10.11. It's not clear whether this is actually causing runtime issues.

Hello dogles,

I have a few questions for you.

  1. Is this an issue that only occurs in 4.11 Preview 3 or does it also happen with previous versions of the engine?

  2. Was this project converted from any previous versions of the engine or newly created for 4.11 Preview 3?

  3. Does this only happen with this project or any that you try to create for 4.11 Preview 3?

I haven't tested a preview release prior to Preview 3. This was not an issue in 4.10. To clarify, this is building UE4Editor itself from Github, not in the context of any game project.

Thank you for that information dogles. It seems there was an issue where one of the libraries for 4.11 Preview 3 was compiled with a newer version than what we support currently. This ended up in the problem you're currently seeing. This may be fixed in Preview 4 but I'm not sure if it was caught before that preview was released. If not, the fix will be coming soon.

Have a nice day!
