inline函数出现 undefined reference 错误 原因:你把inline函数的implementation放到cpp文件里肯定要报这个错误 正确的做法:把inline函数的声明和实现都放到header里,例如 // declaration: return_type function_name(param_type1, param_type2, ...); // implementation: inline return_type function_name(param_type1...
如果将函数的实现放在cpp文件中,并且标记为inline, 那么该函数对其他编译单元不可见(类似static的效果),也就是其他cpp文件不能链接该函数库,这就是标题中出现的 … undefined reference to … 问题原因就是,编译器在编译一个inline函数时,需要知道其完整定义,如果编译器在本编译单元找不到inline函数定义就会报错(inli...
When I build the project with Arm Compiler 6, armlink reports an undefined reference error. For example, consider the following code: foo.cinline int add(int i, int j) { return i + j; } int main(void) { int i = add(4, 5); return i; }...

inline函数需要是internal linkage,而函数默认是具备external linkage,此类函数是无法标识为inline,编译时会出现错误,gcc会提示“undefined reference to xxx”。所以使用inline时,一般要与static标识符一起使用。 实现 1//header.h2#include <stdio.h>3inlinestaticvoidinline_function() {4printf("inline function\n"...
