Currently, the ReadyToRun compiler doesn't support cross-targeting. You must compile on a given target. For example, if you want R2R images for Windows x64, you need to run the publish command on that environment.
Exceptions to cross-targeting:
For some SDK platforms, the ReadyToRun compiler is capable of cross-compiling for other target platforms. Supported compilation targets are described in the below table.
| SDK platform | Supported target platforms |
|---|---|
| Windows X64 | Windows X86, Windows X64, Windows ARM32, Windows ARM64 |
| Windows X86 | Windows X86, Windows ARM32 |
| Linux X64 | Linux X86, Linux X64, Linux ARM32, Linux ARM64 |
| Linux ARM32 | Linux ARM32 |
| Linux ARM64 | Linux ARM64 |
| macOS X64 | macOS X64 |
