例如,如果警告为unused-variable,则可以通过以下方法禁用它: 代码语言:javascript 复制 #pragma clang diagnostic push #pragma clang diagnostic ignored "-Wunused-variable" int a; #pragma clang diagnostic pop 但是问题是,在构建存储库时,我没有在输出中得到警告,我只知道发出警告的是哪个clang检查.在这种情况下,...
-Wall -Wno-unused-variable//启用Wall可是剔除unused-variable 用语句强制开启或者关闭某个警告 强制开启一个警告 #warning"This method can not be used" 强制开启一个错误 #error"You must add this key,or you will fail" 强制关闭一个警告 比如 这里会出现警告test这个selector没有实现 [selfperformSelector...
// 加了个unused的attribute用来消除unused variable的warning __strong void(^block)(void)attribute((cleanup(blockCleanUp), unused)) = ^{ NSLog(@"I'm dying..."); }; } // 这里输出"I'm dying..." | 这里不得不提万能的Reactive Cocoa中神奇的@onExit方法,其实正是上面的写法,简单定义个宏: ...

Wunused-variable Wwrite-strings 困难模式 所谓的困难模式就是开启所有警告,并且把警告当作error。这意味着,只要还有一个警告存在,那么程序将不能编译运行。 参考链接 http://onevcat.com/2013/05/talk-about-warning/ http://programmers.stackexchange.com/questions/122608/clang-warning-flags-for-objective-c-dev...

最近因为一些学习的原因，需要使用一款跨平台的轻量级的GUI+图像绘制 C/C++库。经过一番调研以后，最终从GTK+、FLTK中选出了FLTK，跨平台、够轻量。本文将在Windows、macOS以及Linux Debian三套操作系统环境，对FLTK进行编译，并搭建简单Demo。这其中也有少许的坑，也在此文进行记录。
