如何在OSX 10.9上安装gdb

Question

如何在OSX 10.9上安装gdb？

我尝试使用macports：

port install gdb
Password:
...
--->  Updating database of binaries: 100.0%
--->  Scanning binaries for linking errors: 100.0%
--->  No broken files found.

但是我没有gdb可执行文件：

$ which gdb
$ 

我发现 Mac上的macports gdb叫做ggdb。 所以我建立了一个链接：

sudo ln -s /opt/local/bin/ggdb /opt/local/bin/gdb

$ gdb --args ./prog -time

Starting program: /prog -time
Unable to find Mach task port for process-id 65740: (os/kern) failure (0x5).

(gdb) 

那么如何在OSX 10.9上正确安装gdb呢？

PS相关问题，但没有帮助：

如何在OSX上获得“codesigned”gdb？

“请检查gdb是否为codesigned - 请参阅taskgated（8）” - 如何使用自制程序代码签名安装gdb？

Answer 1

我这样做了（ 这里描述）：

1. sudo nano /System/Library/LaunchDaemons/com.apple.taskgated.plist

   在第22行第27行将选项字符串从-s更改为-sp 。

2. 重启电脑。

3. 使用gdb
