main.o: In function `main': main.c:(.text+0x7): undefined reference to `test' collect2: ld returned 1 exit status 这就是最典型的undefined reference错误,因为在链接时发现找不到某个函数的实现文件,本例中test.o文件中包含了test()函数的实现,所以如果按下面这种方式链接就没事了。 gcc -o main...
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 defining the functions both inline, and compiling a debug build (so it sets the macro DEBUG=1), I get lots of undefined reference errors: src/main_debug.o gcc -osrc/main_debug.o src/main.c -c -Wall -Wextra -Wpedantic -std=gnu11 -march=native -Og -g -DCC="\"gcc\"" -DCF...
/usr/bin/ld: main.o: in function `main': main.cc:(.text+0x36): undefined reference to `test::func()' clang-11: error: linker command failed with exit code 1 (use -v to see invocation) 链接步骤炸了。首先看看是否缺文件: ls *.o ...
inline void f(void) { } int main(void) { f(); } leads to: undefined reference to `f' https://godbolt.org/z/W11hd1MTb
如果是类成员函数,会默认内联的.比如我在Test.H中 定义 pragma once class Test { public:int a;int test() const;};Test.cc中就可以:include "test.h"int Test::test() const { return 0;} main.cc include "test.h"void main(){ Test t;t.test();} 这样比较好.
$(PATH_ONE)/libutil.a(util.o): In function `ZJ::open_max()': util.cpp:(.text+0x56): undefined reference to `err_sys(char const*, ...)' 这里,我知道的是:ZJ::open_max中有对err_sys的调用,我不明白的是:如果确实有undefined reference错误,我没删那两行的时候就该报错了吧?我又没改make...
