Note: There is now experimental support for the [Nix Package Manager](www.nixos.org). If you're a nix user, skip ahead to the [Using Retro68 with Nix](#using-retro68-with-nix) section.
### Prerequisites
- Linux, Mac OS X or Windows (via Cygwin)
@ -143,6 +145,49 @@ The `build-host`, `build-target`, `build-target-ppc` and `build-target-carbon`
directories are CMake build directories generated from the top-level `CMakeLists.txt`,
so you can also `cd` to one of these and run `make` separately if you've made changes.
Using Retro68 with Nix
----------------------
If you are not using the [Nix Package Manager](www.nixos.org), please skip this section. But maybe you should be using it ;-).
Nix is a package manager that runs on Linux and macOS, and NixOS is a Linux distribution based on it.
If you've got `nix` installed, after downloading Retro68, you can run
nix-shell
from the Retro68 directory to get a shell with the compiler tools targeting
68K Macs available in the path, and `CC` and other environment variables already
set up for you. You can then `cd` to one of the example directories or to your
own project and use `cmake` to build it.
You can use the `nix-shell` command to invoke various useful shell environments:
| Command | What |
|-------------------------------------|----------------------------------------------|
| `nix-shell` | 68K development environment |
| `nix-shell -A m68k` | 68K development environment |
| `nix-shell -A ppc` | PowerPC development environment |
| `nix-shell -A retro68.monolithic` | Shell for running `build-toolchain.bash` |
You can also use the `nix-build` command to build packages. As always with `nix`,
the result will be somewhere in a subdirectory of `/nix/store`, with a symlink
named `result` placed in your Retro68 directory.
| Command | What |
|-------------------------------------|----------------------------------------------|
| `nix-build -A m68k.retro68.samples` | Sample programs for 68K |
| `nix-build -A ppc.retro68.samples` | Sample programs for PowerPC |
| `nix-build -A retro68.monolithic` | Result of `build-toolchain.bash --no-carbon` |
| `nix-build -A m68k.zlib` | zlib library, cross-compiled for 68K Macs |
| `nix-build -A m68k.`*packagename* | cross-compile *packagename* to 68K |
| `nix-build -A ppc.`*packagename* | cross-compile *packagename* to PowerPC |
You can attempt to cross-compile *any* package from the `nixpkgs` collection. Unless the
package contains a very portable library, the command will of course fail. Please don't
report bugs, please report successes instead!
