C/C++Eclipse GDB没有显示断点

C/C++ Eclipse GDB not showing break points

本文关键字：显示 断点 GDB C++Eclipse      更新时间：2023-10-16

当我试图在Eclipse中调试代码时，它似乎运行调试器并停止，但Eclipse无法找到源代码？打开一个选项卡，上面写着"main（）at 0x100000f64"，按钮上写着"查看反汇编"

我可以很好地查看反汇编，但如果我能让断点工作，那就太好了。谢谢

我的代码：

#include <iostream>
using namespace std;
int main() {
   int n = 10;
   int factorial = 1;
   // n! = 1*2*3...*n
   for (int i = 1; i <= n; i++) {
      cout << "i is " << i << endl;
      factorial *= i;
   }
   cout << "The Factorial of " << n << " is " << factorial << endl;
   return 0;
}

GDB警告输出：

我也想出了这个。。问题是，当你创建项目时，你需要确保它使用的是Mac GCC而不是llvm来编译。目前，如果使用llvm编译，似乎无法使用gdb进行调试：）
