添加GCC选项C源文件的顶部 [英] Add GCC options to top of C source file

问题描述

时可以放东西在C源文件的顶部，像

Is is possible to put something at the top of the C source file, like

// GCC_OPTIONS=-g,-Wall

这会自动添加这些选项与gcc每次编译该文件的时间？

that will add those options automatically to gcc every time you compile this file?

推荐答案

是的，至少对于一些标志。您可以push和pop 诊断设置是这样的：

Yes it is, at least for some flags. You can push and pop diagnostic settings like this:

#pragma GCC diagnostic error "-pedantic"
#pragma GCC diagnostic warning "-Wall"

此，也可以为<一href=\"http://gcc.gnu.org/onlinedocs/gcc/Function-Specific-Option-Pragmas.html#Function-Specific-Option-Pragmas\"相对=nofollow>在每个功能级别优化级别：

This is also possible for optimization levels on a per-function level:

#pragma GCC optimize ("string"...)
