如何让gdb在OSX 10.11下使用macports工作El Capitan？ [英] How to get gdb to work using macports under OSX 10.11 El Capitan?

问题描述

这源于如何安装gdb（调试器）在Mac OSX El Capitan？。

我有在el capitan下工作的macports没有问题，并且已经安装了gdb端口，但是我无法使编码签名工作。这一切似乎都奏效了。证书在那里，并且设置了始终信任。二进制显示：

  $ codesign -d -v -v / opt / local / bin / ggdb 
 Executable = / opt / local / bin / ggdb 
 Identifier = org.gnu.gdb 
 Format = Mach-O thin（x86_64）
 CodeDirectory v = 20100 size = 25320 flags = 0x0（none）哈希= 1261 + 2 location = embedded 
签名大小= 1392 
 Authority = gdb-cert 
签名时间= 2015年10月23日，07:56:53 
 Info.plist条目= 4 
 TeamIdentifier =未设置
密封资源=无
内部需求计数= 1大小= 88 
  

但是我得到
$ b $ pre $ g

启动程序/ Users / sal / Katiss / ecodriving
无法为进程ID 39278找到Mach任务端口：（os / kern）失败（0x5）。
（请检查gdb是signedigned - 请参阅taskgated（8））

当我尝试开始调试的东西。

任何想法？

$ b
sudo dseditgroup -o编辑-a yourusername -t用户procmod


它将您添加到 procmod 。

这仅仅是因为只有 procmod 中的用户可以使用函数 task_for_pid ，并且您可以发现自己的组 / opt / local / bin / ggdb 是 procmod 。

This arose from How to install gdb (debugger) in Mac OSX El Capitan?.

I have macports working under el capitan no problem and have installed the gdb port but I can't get the codesigning to work. It all seems to have worked. The certificate is there and "Always Trust" is set. The binary shows:

$ codesign -d -v -v /opt/local/bin/ggdb 
Executable=/opt/local/bin/ggdb
Identifier=org.gnu.gdb
Format=Mach-O thin (x86_64)
CodeDirectory v=20100 size=25320 flags=0x0(none) hashes=1261+2 location=embedded
Signature size=1392
Authority=gdb-cert
Signed Time=23 Oct 2015, 07:56:53
Info.plist entries=4
TeamIdentifier=not set
Sealed Resources=none
Internal requirements count=1 size=88

but I get

(gdb) r
Starting program: /Users/sal/Katiss/ecodriving 
Unable to find Mach task port for process-id 39278: (os/kern) failure (0x5).
(please check gdb is codesigned - see taskgated(8))

when I try to start debugging something.

Any ideas?

解决方案

I just settled this problem by using the following command.

sudo dseditgroup -o edit -a yourusername -t user procmod

Which adds you to group procmod.

It's just because only users in procmod can use function task_for_pid, and you can find that the own group of /opt/local/bin/ggdb is procmod.
