How do I close the channel correctly?

Question

As far as I understand the deadlock appears because the channel is not closed. How do I close the channel to get rid of the deadlock?

I use this library to limit the number of goroutines: https://github.com/zenthangplus/goccm

Code:

func main() {
   c := goccm.New(5)
   chanStr := make(chan string)
   lines := []string{"aaaaaa", "fffff", "ddddd", "eeeee"}

   for _, value := range lines {
      value := value
      c.Wait()
      go func() {
         chanStr <- value
         c.Done()
      }()
   }

   for value := range chanStr {
      fmt.Println(value)
   }
   c.WaitAllDone()

}

Before that I did with the channel done to realize that all goroutines are complete and close the channel, but before that I did not limit the number of goroutines.

Read from the channel in another goroutine:

package main

import (
    "fmt"

    "github.com/zenthangplus/goccm"
)

func main() {
    c := goccm.New(2)
    chanStr := make(chan string)
    lines := []string{"aaaaaa", "fffff", "ddddd", "eeeee"}

    go func() {
        for value := range chanStr {
            fmt.Println(value)
        }
    }()

    for _, value := range lines {
        value := value
        c.Wait()
        go func() {
            chanStr <- value
            c.Done()
        }()
    }

    c.WaitAllDone()
    close(chanStr)
}
