让gdb在macos sierra上工作的正确步骤是什么？这是由最新的gdb 8.1造成的，将gdb降级到8.0.1可以解决这个问题 如何降级到gdb 8.0.1
- 取消当前gdb的链接：
brew取消gdb的链接 - 安装gdb 8.0.1:
brew安装https://raw.githubusercontent.com/Homebrew/homebrew-core/9ec9fb27a33698fc7636afce5c1c16787e9ce3f3/Formula/gdb.rb - 可选：避免使用
brew pin gdb升级gdb
但以下步骤有所帮助 （我插入了步骤12，“检查它是否工作”，因为我没有重新启动，而是测试了gdb，它工作得很好。我没有遵循步骤12+）
gdb证书- 标识类型：自签名根
- 证书类型：代码签名
- 检查：让我覆盖默认值
killall taskgatedCodesign-fs-gdb-cert/usr/local/bin/gdbcommand-Rcsrutil启用--无调试赛拉预科：
Sierra:我使用的是macOS 10.13.6，我遇到了相同的问题“（请检查gdb是否进行了代码设计-请参阅taskgated（8）） 当我将GDB从8.2.1降级到8.0.1，然后再次创建并签署GDB证书时，它就工作了
别忘了在eclipse的调试器中将gdb的路径从8.2.1更改为8.0.1，重新启动它就会工作。似乎gdb在macos上被破坏了，请参见和。嘿，我也遇到了同样的问题。你采取了什么措施来解决这个问题？运行程序时是否曾收到此错误：
无法找到进程id 62995:（os/kern）失败（0x5）的Mach任务端口。（请检查gdb是否进行了代码签名-请参阅taskgated（8））GNU gdb (GDB) 8.1
