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"

Warnings as errors

I noticed that we cannot set the compiler options to treat warnings as errors (on Windows) while compiling the engine or the game DLL. What is the reason behind this?

Thanks,

Hi,

Yes, option ‘treat warnings as errors’ is disabled. “Clang on Windows does not respect "#pragma warning (error: ####)", and we are not passing "/WX", so warnings are not treated as errors when compiling on Windows using Clang right now." (c)

UE4 complies with Unreal Build Tool (UBT). You should look for compiler options in VCToolChain.cs Try to add this in line 58

 Arguments.Append(" /WX");


Hope it helps!
