Is there a way to suppress warnings in Xcode? For example I am calling an undocumented method and since the method is not in the header I get a warning on compile. I know I can add it to my header to stop the warning, but I am wondering if there is a way other than adding it to the header (so I can keep the headers clean and standard) to suppress the warning? A pragma or something? robottobor To disable warnings on a per-file basis, using Xcode 3 and llvm-gcc-4.2 you can use: #pragma GCC diagnostic ignored "-Wwarning-flag" Where warning name is some gcc warning flag. This overrides any warning

How to suppress GCC warnings from library headers?

I have a project that uses log4cxx, boost, etc. libraries whose headers generate lots of (repetitive) warnings. Is there a way to suppress warnings from library includes (i.e. #include <some-header.h>) or includes from certain paths? I'd like to use -Wall and/or -Wextra as usual on project code without relevant info being obscured. I currently use grep on make output but I'd like something better. Phi You may try to include library headers using -isystem instead of -I . This will make them "system headers" and GCC won't report warnings for them. For those using CMake, you can modify your

Dynamic forwarding: suppress Incomplete Implementation warning

由 ╄→尐↘猪︶ㄣ 提交于 2019-11-26 09:18:36
问题 I have a class exposing some methods, whose implementation is provided by an inner object. I\'m using forward invocation to dispatch at runtime the method calls to the inner object, but XCode is complaining since it cannot find an implementation of the declared methods. I found some other similar questions on SO, but all of them were solved with a design change. I don\'t mean to have a discussion about the design here, but if anybody has some suggestion about it I have an open question on

What is SuppressWarnings (“unchecked”) in Java?

由 你。 提交于 2019-11-25 23:38:58
问题 Sometime when looking through code, I see many methods specify an annotation: @SuppressWarnings(\"unchecked\") What does this mean? 回答1: Sometimes Java generics just doesn't let you do what you want to, and you need to effectively tell the compiler that what you're doing really will be legal at execution time. I usually find this a pain when I'm mocking a generic interface, but there are other examples too. It's usually worth trying to work out a way of avoiding the warning rather than

How to disable python warnings

由 依然范特西╮ 提交于 2019-11-25 23:29:26
问题 I am working with code that throws a lot of (for me at the moment) useless warnings using the warnings library. Reading (/scanning) the documentation I only found a way to disable warnings for single functions. But I don\'t want to change so much of the code. Is there maybe a flag like python -no-warning foo.py ? What would you recommend? 回答1: There's the -W option. python -W ignore foo.py 回答2: Did you look at the suppress warnings section of the python docs? If you are using code that you
