c++ - gdb 有问题

Question

它说它找不到某个文件或目录 (fxstat.c)。我已经尝试按照互联网上的一些帖子的建议安装 glibc，但它没有用。

这是版本：

和错误信息：

我有一个运行wsl（debian）的相同版本gdb的桌面，我在那里编译了程序，从来没有遇到过这个问题，甚至之前也没有看到过这个错误。我正在使用支持 linux 的 arm64、chromeos pc。这可能是系统问题，但是我该如何解决呢？

编辑：根据 tink 的建议，我添加了丢失源的路径，但它只是内部文件，我仍然得到相同的结果，我的程序只是突然停止。

编辑二：正如 GM 建议的那样，这里是一个示例源，不管它是什么文件。

1   #include<iostream>
  1 
  2 int main() {
  3         std::cout << "hello world" << std::endl;
  4 }

现在有不同的消息：

(gdb) list
1       #include<iostream>
2
3       int main() {
4               std::cout << "hello world" << std::endl;
5       }
(gdb) b main
Breakpoint 1 at 0x9ec: file hello_word.cpp, line 4.
(gdb) r
Starting program: /home/danielnyong66/Codeforces-And-LeetCode-Solutions/hello 

Breakpoint 1, main () at hello_word.cpp:4
4               std::cout << "hello world" << std::endl;
(gdb) n

Program received signal SIGSEGV, Segmentation fault.
strlen () at ../sysdeps/aarch64/strlen.S:94
94      ../sysdeps/aarch64/strlen.S: No such file or directory.

它会查找不在我的程序中的文件，并在找不到它们时显示错误。这是我正在调试的原始文件：https ://repl.it/join/iyqwodtx-danyxng

编辑：回溯...
