gdb不适用于Mac版High Sierra 10.13.3

Question

我用brew安装了gdb 8.1.

我有codeign gdb和.gdbinit如下:

set startup-with-shell off.

我已禁用SIP功能:

$ csrutil status
System Integrity Protection status: disabled.

但是gdb仍然不起作用:

#include <iostream>
using namespace std;

int main() {
  cout << "hello world!" << endl;
  return 0;
}

编译命令:

g++ -g test.cpp

gdb输出:

使gdb在macos sierra上运行的正确步骤是什么？

这是由最新的gdb 8.1引起的,将gdb降级到8.0.1可以解决这个问题.

如何降级到gdb 8.0.1

• 取消链接当前gdb: brew unlink gdb
• 安装gdb 8.0.1: brew install https://raw.githubusercontent.com/Homebrew/homebrew-core/9ec9fb27a33698fc7636afce5c1c16787e9ce3f3/Formula/gdb.rb
• 可选:避免使用升级gdb brew pin gdb
