gdb 不适用于 macos High Sierra 10.13.3 [英] gdb doesn't work on macos High Sierra 10.13.3

问题描述

我已经用 brew 安装了 gdb 8.1.

I have installed gdb 8.1 with brew.

我也有 codesign gdb 和 .gdbinit 如下:

I have codesign gdb also and .gdbinit as below:

set startup-with-shell off.

我已禁用 SIP 功能:

I have disabled SIP feature:

$ csrutil status
System Integrity Protection status: disabled.

但是gdb还是不行:

#include <iostream>
using namespace std;

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

编译命令:

g++ -g test.cpp

gdb 输出:

让 gdb 在 macos sierra 上工作的正确步骤是什么?

What correct steps to make gdb work on macos sierra?

推荐答案

这是最新的gdb 8.1造成的，将gdb降级到8.0.1可以解决这个问题.

This is caused by latest gdb 8.1, downgrade gdb to 8.0.1 could solve this problem.

• 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 brew pin gdb
升级 gdb

• Unlink current gdb: brew unlink gdb
• Install gdb 8.0.1: brew install https://raw.githubusercontent.com/Homebrew/homebrew-core/9ec9fb27a33698fc7636afce5c1c16787e9ce3f3/Formula/gdb.rb
• Optional: avoid upgrade gdb with brew pin gdb
