The 22-year-old had signed a pre-contract agreement to join the Blues this summer.
However, a fee has been agreed for the transfer to happen this month.
Neither side have revealed the exact financial details of Callacher's move.
His Glentoran deal was set to expire this summer and the east Belfast club had held contract talks.
However, after they broke down, the club said it had "no interest" in keeping the player.
In a statement, Glentoran said: "We would like to thank him for his service and wish him a long and successful career at Linfield."
