-Werror-implicit-function-declaration 是GCC(GNU Compiler Collection)编译器的一个编译选项。这个选项将隐式函数声明的警告(-Wimplicit-function-declaration)提升为错误。默认情况下,当编译器遇到一个未声明的函数时,它会发出警告并假定该函数返回 int 类型。启用 -Werror 后,这些警告会被视为错误,导致编译失败。

error: implicit declaration of function 'm' is invalid in C99 [-Werror,-Wimplicit-function-declaration] (gcc 中会报出 warning,而不是 error) 经过排查,发现是没有在头文件那里提前声明自定义函数,所以提前声明之后再进行编译就 OK 了. 这种声明称为函数原型,作用是让编译器在编译时对程序中的函数调用检...
