如何在IDA中将其他库连接到二进制文件

Question

test.c的

#include <stdio.h>
void libtest1();  //from libtest1.so

int main()
{
    libtest1();  //calls puts() from libtest1.so twice
    libtest1(); 
    puts("-----------------------------");
    return 0;
}

libtest1.c

#include <stdio.h>

void libtest1()
{
    puts("libtest1: 1st call to the original puts()");
    puts("libtest1: 2nd call to the original puts()");
}

libfaketest1.c

#include <stdio.h>
void func1()
{
    puts("func 1 fakelib");

}
void libtest1()
{
    puts("libfaketest1:1st call to the fake puts()");
    puts("libfaketest1:2nd call to the fake puts()");
}

我将libtest1.c和libfaketest1.c编译为共享库：libtest1.so，libfaketest1.so。

test.c到Linux二进制文件与dependents libtest1.so，而不是libfaketest1.so！

在IDA中打开测试二进制文件

导入表：

如何在不更换IDA中的原始lib libtest1.so的情况下连接二进制libfaketest1.so？ 我想从libfaketest1.so调用函数.text:00000000004006A9 call _libtest1。
