Xcode

Xcode (not XCode) is a unified Apple IDE for OSX and iOS development.

It must be installed on OSX in order to get all build utils, which FPC depends on.

Xcode 5.0

Apple removed "gdb" from it's binary utils. Lazarus is currently only able to used "gdb" as an external debugger. "Gdb" should be installed from the third party.

Xcode 7.0

• If after the update to the version your projects are failing to compile and you're using FPC 2.6.4 (or earlier) -> change your debug info type from "Automatic" to "Dwarf". Apple's linker stops supporting .stabs information (which is used by default).
• Alternatively you could download the previous version 6.4
  • Download xcode 6.4 , and change the folder name to xcode6.4 before copy to /Application
  • So you have two xcode now, and switch your command line tools using Xcode6.4

# sudo xcode-select -switch /Applications/Xcode6.4/Xcode.app
