英文:
Go pprof not working properly
问题
我正在尝试让pprof与Golang一起工作。
--text 似乎可以正常工作，但大多数其他选项都无法正常工作。
例如，使用 pdf 选项：
root@ubuntu:/home/user/IdeaProjects/go_projects/src# go tool pprof --pdf ./src /tmp/profile578584736/cpu.pprof > out.pdf
sh: 1: dot: not found
root@ubuntu:/home/user/IdeaProjects/go_projects/src#
使用 gv 选项：
root@ubuntu:/home/user/IdeaProjects/go_projects/src# go tool pprof --gv ./src /tmp/profile578584736/cpu.pprof
sh: 1: dot: not found
gv -scale 0
Can't exec "gv": No such file or directory at /usr/local/go/pkg/tool/linux_386/pprof line 719.
root@ubuntu:/home/user/IdeaProjects/go_projects/src#
我需要在Go中进行一些更改才能使其正常工作吗？
英文:
I'm trying to get pprof working with Golang.
--text seems to work fine but most of other options does not work.
For instance with pdf:
root@ubuntu:/home/user/IdeaProjects/go_projects/src# go tool pprof --pdf ./src /tmp/profile578584736/cpu.pprof > out.pdf
sh: 1: dot: not found
root@ubuntu:/home/user/IdeaProjects/go_projects/src#
With gv:
root@ubuntu:/home/user/IdeaProjects/go_projects/src# go tool pprof --gv ./src /tmp/profile578584736/cpu.pprof
sh: 1: dot: not found
gv -scale 0
Can't exec "gv": No such file or directory at /usr/local/go/pkg/tool/linux_386/pprof line 719.
root@ubuntu:/home/user/IdeaProjects/go_projects/src#
Is there something that I need to change in Go to get it working?
