I am trying to learn Hugo using a Go debugger called dlv. And I am pretty stuck. After:
go get -v github.com/gohugoio/hugo
cd $GOPATH/src/github.com/gohugoio/hugo
go build -gcflags="-N -l"
dlv exec ./hugo -- -s /path/to/the/projectdir
This hangs. Pressing Ctrl+C runs hugo as normal. As far as I can see dlv debug not only produces the same behavior but it's the exact same: the produced binary called debug is the exact same as the hugo I built with go build -gcflags="-N -l".
dlv launches a number of child processes, these disappear after a while. The hugo process is visible via ps and pidof hugo but strace -ppidof hugo`` reports strace: attach: ptrace(PTRACE_ATTACH, ...): No such proce. Checking after, it's still in the ps list, the same pid. I would guess because it's in t state as it is being traced.
How could I then watch Hugo running?
Hmm, doesn't happen for me. dlv prompt appears right away. I am on fedora, have been using hugo regularly over the past week or so.
$ dlv exec ./hugo -- --cleanDestinationDir -s /path/to/blog/root/
