If I want D on Windows XP, what can I do?

If I try download dmd it doesn't work. LDC doesn't seem to work 
either.

Are there any changes I have to do to make it work?

Thanks in advance!

You need to bootstrap yourself in order for it to run on dmd. Good luck.

"Doesn't work" isn't good enough if you want anyone to help you

I modified the PE header (set major version and subsystem to 5) and it worked 🌞 No idea how much ub this causes tho.

Care to explain this in beginner-friendly way? I think it's likely it will help other people with same kinds of problems. DMD for Windows should work just as well in XP as in later versions, as far as I know. I don't think it depends on any functionality introduced after XP.

operating system + druntime bindings might be the only issue. Support for XP was dropped because it went EOL and that's it. The compiler itself just needs to read files, write files, call processes and that's it.

Yeah, maybe, idk actually. Imo dmd should be compiled with Major version 5 :>

Typically, the reason D stops supporting older OSes is because something changes that is fundamental to the language. My understanding is that something changed in how thread-local-storage is supported, so XP is no longer valid for the current compilers. I could be wrong, but I'm pretty sure there was a definite reason for dropping support, even if it wasn't TLS. Of course, you can still use an older compiler. -Steve

As I said I modified the PE header and dmd seems to run without any problems. Hard to tell what edge cases there are though.

My recollection is that dropping official support for Windows XP was based on workload rather than any technical reason, and simultaneously that policy is to "soft support" it by accepting any patches that fix Windows XP problems and not deliberately doing things to break Windows XP.

Sure, you can use any PE editor or even a hex editor. I used https://petoolse.github.io/petools/ Open dmd.exe and edit major version and subsystem version (change from 6 to 5). https://ibb.co/0hpFmd9 Done :)

XP has terrible support for thread-local storage when DLLs are involved. Other than that, it should work fine. I use XP as a test machine for the DMC++ compiler, because later versions of Windows attempt to run the virus checker every time the compiler generates an executable. Even when the damned virus checker is turned off. The trouble with the wretched virus checker is it holds on to the exe file even if it is deleted. The next write of the file with the same name then fails. DMC++ is compiled with DMD. I'm not sure which version of DMD is building it, as my code doesn't aggressively use new D features I haven't been motivated to upgrade it.

Do you have exclusions set? On Windows 10, you can go to Start > Virus & Thread protection > Manage Settings > Add or remove exclusions > Add an exclusion. I exclude a whole bunch of folders such as: C:\D\dmd2\windows\bin C:\Users\Dennis\AppData\Local\Temp\.rdmd I found that it really helps reducing the time to run .exe files, though it's still slower than on Linux (which is why I'm using Debian most of the time).

Yeah, I did the equivalent on Win7. It only reduces the problem.
