Why all warnings are treated as errors in the ue4 C++ project, and how to suppress all warnings?

[anonymous_user_841b3986]

Why would you want to suppress a warning though? It takes the same amount of time to correct the code as it does to suppress the warning and one day you will get an error and wonder why you never got a warning about it.

The only type of warnings I would suppress is deprecation warnings when I want to use some old code for whatever reason.

If you are using some old poorly written code filled with warnings you might want to spend a day cleaning it up as it probably has some faulty logic as well.

Hello @ , thanks for your reply.

I agree with your opinions about coding writting. I am using a third party C++ library and you can trust that the logic is right, but I still get massive “errors” because all warnings are treated as errors. It’s time-consuming to clean all warnings in a huge C++ library, so is there any solution to suppress all warnings? Can your help me?

And I’m also curious about another problem: In ordinary C++ projects, [FONT=courier new]cl.exe won’t treat warnings as errors. But which arguments cause [FONT=courier new]cl.exe treats warnings as errors in UE C++ projects?
