Question

Lib1.a:

#include<stdio.h>
#include<stdlib.h>
class Lib
{
public:
inline static const void Test()
{
printf("this is lib1\n");
};
void Lib1Test()
{
Lib::Test();
}
};

Lib2.a:

#include<stdio.h>
#include<stdlib.h>
class Lib
{
public:
inline static const int Test()
{
printf("this is lib2\n");
};
void Lib2Test()
{
Lib::Test(); // this will call the Test in Lib1,amazing!
}
};

lib1.a and lib2.a will be linked to test together.

What’s the reason? Did not Lib::Test redefine?

Answer 1

Did not Lib::Test redefine

As dribeas already answered, your program is ill-formed (violates one-definition rule).

To understand why it does not fail to link, read about COMDAT sections here.
