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"

Having a warning in compilation tempnam

It is not a problem for but I just wanna ask if it good to ignore it or give a right solution about my warning message /home/tiny/Documents/UnrealEngine-release/Engine/Source/ThirdParty/FBX/2016.1.1/lib/gcc4/x86_64-unknown-linux-gnu/release//libfbxsdk.a(fbxutils.o): In function `fbxsdk::FbxPathUtils::GenerateFileName(char const*, char const*)': (.text+0x4b8): warning: the use of `tempnam' is dangerous, better use `mkstemp

I can not edit it nor open the file it say so what kind of thing I will do. Just a minor problem but it's better if someone can explain regarding this topic. Thanks for the answer.
