minGW Windows support in-scope? about cosmopolitan HOT 3 CLOSED

You can compile an x86_64-linux-gnu cross compiler toolchain for Windows. But I recommend just running Linux in a virtual machine and using that to compile. Builds actually go faster in a virtual machine on Windows than on Windows itself. It's not possible to support a MinGW toolchain because it uses COFF, which imposes restrictions on things like the length of section names that would otherwise make Actually Portable Executable impossible. The same is true of Mach-O. You have to use an ELF toolchain. It's totally possible to have an ELF toolchain on Windows. It's just prebuilt binaries for such a thing are hard to find online and it's hard to configure a build from scratch to create them.

Regarding the integrated linker, I'm assuming you're referring to 81ef162 which is discussed further in https://github.com/jart/cosmopolitan/blob/master/third_party/chibicc/README.cosmo An integrated linker would be nice, since the chibicc compiler can be built as an actually portable executable. Keep in mind it's not a replacement for GCC which has decades of development behind it and can generally produce code that's twice as fast.

There's now a tutorial on the website on how to build Actually Portable Executables on Windows. Static binaries are provided of an x86_64-linux-gnu cross-compiler toolchain which runs on Windows. https://justine.lol/cosmopolitan/windows-compiling.html
