Set breakpoint by sourcefile in Delve
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
How can I set a breakpoint by sourcefile?
I have the following code in a tmp.go file.
package main
func main() {
a, b := 1, 2
c := a + b
println(c)
}
This works
$ dlv debug ./tmp.go
(dlv) b main.main:1
Breakpoint 1 set at 0x105395d for main.main() ./tmp.go:4
But this fails
$ dlv debug ./tmp.go
(dlv) b ./tmp.go:4
Command failed: Location "./tmp.go:4" not found
Edit:
This works
$ dlv debug ./tmp.go
(dlv) b tmp.go:4
Breakpoint 1 set at 0x105395d for main.main() ./tmp.go:4
Any ideas what might be wrong with my environment?

Any ideas what might be wrong with my environment?
Why should this question be closed?
off-topic because...
Questions seeking debugging help ("why isn't this code working?") must
include the desired behavior, a specific problem or error and the
shortest code necessary to reproduce it in the question itself.
Questions without a clear problem statement are not useful to other
readers. See: How to create a Minimal, Complete, and Verifiable
example.
You didn't provide an MCVE, so we can only guess.
We have no idea what is in your main.go
, so how do you expect us to know what your problem is?
For example, just a guess, with an MCVE,
main.go
:
package main
func main() {
a, b := 1, 2
c := a + b
println(c)
}
Playground: https://play.golang.org/p/i2D9uZnFlXn
Output:
$ go run main.go
3
$ dlv debug ./main.go
Type 'help' for list of commands.
(dlv) break main.main:4
Breakpoint 1 set at 0x454bda for main.main() ./main.go:7
(dlv) quit
$ dlv debug ./main.go
Type 'help' for list of commands.
(dlv) break main.go:4
Breakpoint 1 set at 0x454b9d for main.main() ./main.go:4
(dlv) quit
$
break main.main:4
and break main.go:4
are not the same thing, at ./main.go:7
and at ./main.go:4
respectively. Line numbers are relative to files, functions, etc.
Thank you for the comment. I update the question to use your example.
