英文:
Golang profiler cannot find source code
问题
我已经在我的代码中包含了net/http/pprof包。然后我可以轻松地运行pprof分析器（在Debian上）：
go tool pprof http://localhost:9000/debug/pprof/profile
诸如top10或生成调用图等命令都能正常工作。然而，一旦我尝试进入一个函数，就会失败：
(pprof) list MyFunc
没有mypkg.MyFunc的源代码信息
我的GOPATH设置为我的项目目录。在构建源代码或运行pprof时，我需要特殊的标志或环境变量吗？
英文:
I've included the net/http/pprof package in my code. I can then comfortably run the pprof profiler (on Debian):
go tool pprof http://localhost:9000/debug/pprof/profile
Commands such as top10 or even generating call graphs work as expected. However, as soon as I try to go into a function, it fails:
(pprof) list MyFunc
No source information for mypkg.MyFunc
My GOPATH is set to my project's directory. Do I need any special flags or environment variables while building my source code or while running pprof?

通过golang-nuts的帮助找到了答案。我需要指定二进制文件：
go tool pprof mybinary http://localhost:9000/debug/pprof/profile
这样就可以找到源代码，并可以使用"list"命令列出。
英文:
Found the answer with the help of the golang-nuts people. I needed to specify the binary:
go tool pprof mybinary http://localhost:9000/debug/pprof/profile
This way the source code is found and can be listed with the "list" command.

我在Windows上遇到了与"net/http/pprof"相同的问题。不过，使用"runtime/pprof"代替，并使用pprof.StartCPUProfile / StopCPUProfile解决了这个问题。
英文:
I had the same problem with "net/http/pprof", albeit on windows.
Using "runtime/pprof" instead, with pprof.StartCPUProfile / StopCPUProfile solved it.
