[Question] Can I do cross compiling, and how?

Overview

Can I generate linux or macos executable on windows? If I can, how? If I can't, will this be supported in the future?

Reference

I saw this on Link to C3 web

  "output": "../build",
  // Architecture and OS target.
  // You can use 'c3c --list-targets' to list all valid targets,
  // "target": "windows-x64",
  // Current Target options:
  //    android-aarch64
  //    elf-aarch64 elf-riscv32 elf-riscv64 elf-x86 elf-x64 elf-xtensa
  //    mcu-x86 mingw-x64 netbsd-x86 netbsd-x64 openbsd-x86 openbsd-x64
  //    freebsd-x86 freebsd-x64 ios-aarch64
  //    linux-aarch64 linux-riscv32 linux-riscv64 linux-x86 linux-x64
  //    macos-aarch64 macos-x64
  //    wasm32 wasm64
  //    windows-aarch64 windows-x64
  "targets": {
    "linux-x64": {
      // Executable or library.
      "type": "executable",
      // Additional libraries, sources
      // and overrides of global settings here.
    },
  },

However, I can't build project as linux executable on windows, I'm a little confused.

[Book-reader]

That page is a bit misleading, targets in the project.json can have any name and it doesn't affect what platform it compiles to.
Setting "target": "linux-x64" or compiling with --target linux-x64 will compile it to linux. That said I also don't know if it's currently possible to cross-compile from linux to windows, but if previously building would create a windows exe then try the above.

[Book-reader]

In fact it looks like whoever wrote that page might have mixed up targets and target, since I don't see it mention target

[Sorrow-Scarlet]

OK... So for now, I need sth like github action to do such thing...

[lerno]

I fixed that page now.

[Sorrow-Scarlet]

OK
