Introduction
Darwin is the target for macOS and iOS, both PowerPC, ARM and ARM64, i386 and X86_64. Programs may also be run on a machine with only Darwin installed.
Installation
See Installing Lazarus on macOS.
Usage
Lazarus is a Delphi-style RAD environment
A free IDE in the classic Mac style
- Any Editor (AlphaX, BBedit, ...) and command line (fpc your_pascal_program.pas)
Universal binaries
Normally for each processor - operating system combination there is one executable, but in macOS you can combine an aarch64 (ARM64) binary and an x86_64 binary into a so-called "universal binary" or "multi-architecture binary" that will run on both Apple ARM64 processors and Intel 64 bit processors. To do this the ARM64 and x86_64 executables have to be compiled separately and then combined using the lipo command line utility.
It is also possible to combine a PowerPC binaries and an x86 binaries into a single combined binary using the lipo command line tool. You would need to first download the PowerPC cross-compiler so you only need to use ppcppc instead of fpc to build your project to generate the PowerPC binary. If you have a PowerPC computer, then the simplest solution is to build the x86 binary on a different computer with x86 architecture.
