Go: print variables with gdb

Question

In this program, how can I break execution with the debugger and print the value of i?

package main import "fmt" func main() { x := "abc" i := 3 fmt.Println(i) fmt.Println(x) } 

I can not print i. However, I can print x:

 go build test.go gdb test [...]Reading symbols from /home/ned/test...done. (gdb) br 9 (gdb) run (gdb) pi No symbol "i" in current context. (gdb) px $1 = "abc" 

Answer 1

It looks like the variable i was probably optimized due to the existence of the compiler. Have you tried building debugging?

You can use go build -gcflags '-N' .
