英文:
Undefined info command: "goroutines"
问题
我是你的中文翻译助手，以下是翻译好的内容：
我对golang还不熟悉。我正在调试我的go应用程序。
当我尝试运行"info goroutines"时，它报错：
未定义的info命令："goroutines"。
尝试"help info"。
我在我的gdb配置中漏掉了什么？
英文:
I'm new to golang. I was debugging my go application.
While I tried to run "info goroutines", it threw out:
Undefined info command: "goroutines".
Try "help info
What did I miss in my gdb configuration?

文章《使用GDB调试Go代码》提到：
（gdb）info goroutines
但只是在加载给定二进制文件的扩展脚本的上下文中提到。
工具链使用此功能来扩展GDB，以便检查运行时代码（如goroutines）的内部，并对内置的map、slice和channel类型进行漂亮的打印。
如果你想看看这是如何工作的，或者想要扩展它，请查看Go源代码分发中的src/pkg/runtime/runtime-gdb.py。它依赖于一些特殊的魔术类型（
hash<T,U>）和变量（runtime.m和runtime.g），链接器（src/cmd/ld/dwarf.c）确保在DWARF代码中描述了它们。
如果你对调试信息的样子感兴趣，运行'
objdump -W 6.out'并浏览.debug_*部分。
因此，请确保在调试会话中启用这些扩展。
英文:
The article "Debugging Go Code with GDB" does mention:
(gdb) info goroutines
But only in the context of loading extension scripts for a given binary.
> The tool chain uses this to extend GDB with a handful of commands to inspect internals of the runtime code (such as goroutines) and to pretty print the built-in map, slice and channel types.
> If you'd like to see how this works, or want to extend it, take a look at src/pkg/runtime/runtime-gdb.py in the Go source distribution.
It depends on some special magic types (hash<T,U>) and variables (runtime.m and runtime.g) that the linker (src/cmd/ld/dwarf.c) ensures are described in the DWARF code.
> If you're interested in what the debugging information looks like, run 'objdump -W 6.out' and browse through the .debug_* sections.
So make sure your debug session is run with those extensions activated.

在gdb会话中运行以下命令：
source $GOROOT/src/runtime/runtime-gdb.py
其中$GOROOT是Go的安装路径（可以使用go env | grep ROOT查看）。
根据Golang文档的建议，你应该使用https://github.com/go-delve/delve作为调试工具。
英文:
in the gdb session run
source $GOROOT/src/runtime/runtime-gdb.py
where $GOROOT is go lives (see go env | grep ROOT)
you should use https://github.com/go-delve/delve as recommended by golang docs https://golang.org/doc/gdb
