gdb在macos High Sierra 10.13.3上不起作用 [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。

我还有codeign gdb和.gdbinit，如下所示：

set startup-



我禁用了SIP功能：

  $ csrutil status 
系统完整性保护状态：已禁用。 
  

但是gdb仍然不起作用：



  #include< iostream> 
使用namespace std; 
 
 int main（）{
 cout<< 你好，世界！ << ENDL; 
返回0; 
 
  

编译命令：

  g ++ -g test.cpp 
  

gdb输出：

使gdb能够在macos sierra上工作的正确步骤？

解决方案

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

• 取消当前gdb的链接： 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
$ b升级gdb $ b

I have installed gdb 8.1 with brew.

I have codesign gdb also and .gdbinit as below:

set startup-with-shell off.

I have disabled SIP feature:

$ csrutil status
System Integrity Protection status: disabled.

But gdb still doesn't work:

#include <iostream>
using namespace std;

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

Compile command:

g++ -g test.cpp

gdb output:

What correct steps to make gdb work on macos sierra?

解决方案

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

How to degrade to gdb 8.0.1

• 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
