Active breakpoints ignored when running debug launch file. [apple architecture]

[mpurnyn]

I have read through similar issues, stack overflow, and the troubleshooting guides, but no solution seems to work.

I have no issue with building/running go projects, but if I try to set a breakpoint then it's never triggered.

Describe the bug

A clear and concise description of what the bug.

• Breakpoints don't trigger when debugging.
  A clear and concise description of what you expected to happen.
• Breakpoints should stop.

Steps to reproduce the behavior:

1. Set a breakpoint in the for loop for this test:

main.go

package main

import (
	"fmt"
)

//TIP <p>To run your code, right-click the code and select <b>Run</b>.</p> <p>Alternatively, click
// the <icon src="AllIcons.Actions.Execute"/> icon in the gutter and select the <b>Run</b> menu item from here.</p>

func main() {
	//TIP <p>Press <shortcut actionId="ShowIntentionActions"/> when your caret is at the underlined text
	// to see how GoLand suggests fixing the warning.</p><p>Alternatively, if available, click the lightbulb to view possible fixes.</p>
	s := "gopher"
	fmt.Printf("Hello and welcome, %s!\n", s)

	for i := 1; i <= 5; i++ {
		//TIP <p>To start your debugging session, right-click your code in the editor and select the Debug option.</p> <p>We have set one <icon src="AllIcons.Debugger.Db_set_breakpoint"/> breakpoint
		// for you, but you can always add more by pressing <shortcut actionId="ToggleLineBreakpoint"/>.</p>
		fmt.Println("i =", 100/i)
	}
}

2. create a launch file

launch.json

    {
      "name": "TestProject Debug",
      "type": "go",
      "request": "launch",
      "mode": "debug",
      "program": "/Users/peterpurnyn/GolandProjects/testproject/main.go",
      "trace": "verbose",
      "buildFlags": [
        "-gcflags=all=-N -l"
      ]
    }

3. run the debugger

[mpurnyn]

This was an issue on my end where goarch was set to amd64 instead of arm64 (for other reasons).
So dlv was building the code, but for amd64 and ignoring the breakpoints.

closing issue as it's unrelated to vscode.
