Mac OS X无法运行GDB [英] Mac OS X cannot run GDB

问题描述

计算机设置：Mac OS X Yosemite

Computer setup: Mac OS X Yosemite

我的gdb功能很好。但是今天，

My gdb functions well before. But today,

当我尝试使用gdb调试：

When I try to use gdb to debug:

(gdb) run 
Starting program: /Users/JackZhao/Desktop/work/reviewC/pp 
Unable to find Mach task port for process-id 627: (os/kern) failure (0x5).
(please check gdb is codesigned - see taskgated(8))

我尝试添加这样的钥匙链

和这个：
https：// sourceware.org/gdb/wiki/BuildingOnDarwin

I tried to add key chain like this; http://ntraft.com/installing-gdb-on-os-x-mavericks/ and this: https://sourceware.org/gdb/wiki/BuildingOnDarwin

然后重启电脑。但是问题仍然存在。

And restart my computer. But the problem is still there.

推荐答案

这可以通过在任务设置中设置-p来修复：

This can be fixed by setting the -p in the taskgated plist:

编辑（作为sudo）： /System/Library/LaunchDaemons/com.apple.taskgated.plist

edit (as sudo): /System/Library/LaunchDaemons/com.apple.taskgated.plist

        ... <snip> ...

        <key>ProgramArguments</key>
        <array>
                <string>/usr/libexec/taskgated</string>
                <string>-sp</string>
        </array>

从任务组件手册：

OPTIONS
 -p       Accepts the old (Tiger) convention that a process with a primary effective group of procmod or procview is allowed to get task ports. Without this option, this legacy mode
          is not supported.
