调用静态库中定义的全局函数导致链接器错误

Question

I have created a simple static library project and a Win32 console project to call a function.

// static lib code
// Test.h
void abf();

// Test.cpp
void abf()
{
}

// Caller Project code
// MyTest.cpp
#include "Test.h
int main()
{
    abf();
    return 0;
}

Static library compiles without an error. But caller project gives following error.

error LNK2019: unresolved external symbol "void __cdecl abf(void)" (?abf@@YAXXZ) referenced in function _main

I tried a few things such as putting the function in extern "C" block, exporting using __declspec(dllexport) but nothing seems to work.

Any ideas?

在 test.h 中使用 __declspec(dllexport) 导出您的符号

extern "C" __declspec(dllexport) void abf(void);
