Still unable to debug embedded Go?

[antZengger]

Hi,

Recently I need to debug an embedded Go snippet. I compiled my Go code into .so file and loaded it in my C program. However, I found that dlv seems unable to debug to Go parts.

similar issues and talk:

[1] https://github.com/go-delve/delve/issues/873

[2] https://groups.google.com/g/golang-nuts/c/ywzTYaalWLE/m/kn4GoobJAAAJ

the above links are opened in 2017 but seem still unresolved now. Is there any progress?

go source:

package main

import "C"

import (

    "sync"

    "time"

    "fmt"

)

func sum(a, b int) int {

        return a + b

}

func gof() {

    i := 0

    for {   

        fmt.Println(sum(i+1, i+2))

        i++

        time.Sleep(time.Second) 

    }

}

//export updateHeader

func updateHeader() {

    wg := sync.WaitGroup{}

    wg.Add(1)

    go func() {

        gof()

    } ()

    wg.Wait()

}

func main() {}

compile command:

go build -buildmode=c-shared -gcflags "all=-N -l" -o test.so test.go

C code:

#include"test.h"

int main() {

  updateHeader();

}

compiled command:

gcc -g -fno-asynchronous-unwind-tables -o main test.c test.so

After doing the above things, I tried both "dlv exec" and "dlv attach", both of them seems not work as expected, both cannot set breakpoint and list goroutines, etc.
