First off, we are always happy to have new users in the group. But one more bit of etiquette - Please don't post screenshots of text. Instead copy paste the text into the message. I like to use fixed width font, or put it in a code block. See the recent discussion at https://groups.google.com/d/topic/golang-nuts/KR_JXhBWCk8/discussion for the many reasons why.
Looking at the screenshot, I see that you are trying to debug into a runtime library function. That is why it is optimized. IIRC, the way you have built will only build main.go without optimization, but it will not effect the standard libraries. I think you want something like *go build -o main -gcflags "all=-N -l" main.go *. The "all=" is the key here.
