Supported Platforms
4.0 beta 4 includes several updates to how different operating systems and hardware are handled. This allows us to add Apple Silicon (M1) support, and also better handles other devices like the Raspberry Pi.
The final decision is that a “variant” should consist of the OS name (windows, macos, or linux) followed by a the naming from the os.arch value returned by System.getProperty(). Because those names can vary across JDK implementations, we'll be using the name used by the JDK included with the Processing download, which is currently from Adoptium.
This new {os}-{arch} helps drastically simplify the code inside the PDE, and also gets us out of the business of deciding how to rename each platform. While the naming is sometimes awkward (i.e. macos-x86_64), the alternatives are inelegant as well, so we'll err on the side of simplicity by inheriting how the platform handles naming.
As a result of these changes, the subfolders used to identify native libraries for each platform are different. Old libraries will still work, but you're strongly encouraged to use these new names for clarity.
| Hardware/OS | os.arch |
bits | 4.0 library folder name | old library folder name | download suffix |
|---|---|---|---|---|---|
| macOS (Intel 64-bit) (i.e. M1) | aarch64 | 64 | macos-aarch64 | — | macos-aarch64 |
| macOS (Apple Silicon) | x86_64 | 64 | macos-x86_64 | macosx | macos-x64 |
| Windows (Intel 64-bit) | amd64 | 64 | windows-amd64 | windows64 | windows-x64 |
| Linux (Intel 64-bit) | amd64 | 64 | linux-amd64 | linux64 | linux-x64 |
| Linux (Raspberry Pi 32-bit) | arm | 32 | linux-arm | linux-armv6hf | linux-arm32 |
| Linux (Raspberry Pi 64-bit) | aarch64 | 64 | linux-aarch64 | linux-arm64 | linux-arm64 |
(The “bits” column is equivalent to sun.arch.data.model)
Technically, the Raspberry Pi releases may run on other ARM Linux installations, but they aren't tested that way. And the Raspberry Pi version includes additional libraries that are specific to the Pi. Put another way, generic Linux on ARM is not a supported platform, so we don't list it as “Linux (ARM 32-bit)” in places like Export to Application.
You can also view the Supported Platforms from 3.x, though half that information will be out of date.
