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"

update to 4.7 preview 4 renders error

I compiled and used this code in this exact condition under preview 1. When I updated to preview 4 it gave me these two errors.

Error 2 error CS0101: The namespace '' already contains a definition for 'WebBrowser' c:\Program Files\Unreal Engine\4.7\Engine\Source\Runtime\WebBrowser\WebBrowser.Build.cs 5 14 librythianChronicles

and

Error 1 error CS0101: The namespace '' already contains a definition for 'CEF3Utils' c:\Program Files\Unreal Engine\4.7\Engine\Source\Runtime\CEF3Utils\CEF3Utils.Build.cs 5 14 librythianChronicles

Any and all help is much appreciated!!

If it helps, I have not edited or created any files that have to do with the errors.

Hi Jaguar662,

It looks like you may have used source code from GitHub to build your Engine. Is that correct? If so, the source code contained in the 4.7 branch is not the same as the preview versions that are available through the Launcher, and we do not recommend using the 4.7 branch for project development. Since it has code submissions being added to it regularly, it is highly unstable. We did recently add some 4.7 preview tags to the source code on GitHub, and syncing to one of these tags will provide you with a build that is nearly identical to the binary previews available through the Launcher. However, it will still be unstable and potentially prone to errors.

Having said that, are you still seeing these errors? Do you see them when trying to build the Engine, or when building your project?

Hi Jaguar662,

We have not heard from you for a while. Do you still see these errors in the released version 4.7.0? I will be marking this issue as resolved for tracking purposes, but please feel free to re-open this post if you need any more help.
