代码

c 复制代码

//main.c
extern void func_a();

int main (int argc, char *argv[])
{
    func_a();
    return 0;
}

c 复制代码

//a.c
#include <execinfo.h>
#include <stdio.h>
#include <stdlib.h>

void print_trace (void){
    void *array[10];
    size_t size;
    char **strings;
    size_t i;
    
    size = backtrace(array, 10);
    strings = backtrace_symbols(array, size);
    if (NULL == strings){
        perror("backtrace_synbols failed:");
    }
    else{
        printf ("Obtained %zd stack frames.\n", size);
        for (i = 0; i < size; i++)
            printf ("%s\n", strings[i]);
        free (strings);
        strings = NULL;
    }
}

extern void func_b();

void func_a(){
    func_b();
}

c 复制代码

//b.c
extern void print_trace (void);

void func_c(){
    print_trace();
}
void func_b(){
    func_c();
}

编译

bash 复制代码

gcc -c a.c -fpic
gcc -c b.c -fpic
gcc -shared a.o -o liba.so
gcc -shared b.o -o libb.so
gcc main.c -L ./ -la -lb -o test

运行

bash 复制代码

export LD_LIBRARY_PATH=$(pwd):$LD_LIBRARY_PATH
./test

结果

bash 复制代码

./test
