[Classic] Where's the build documentation?

[pistasjis]

Hi, I'm trying to build Waterfox Classic on Windows. I have most of everything installed, but the documentation on Mozilla's site is too new, so things aren't quite working. Is there any documentation to build Waterfox Classic? I try to build, but I just run into all sorts of errors, and I can't find anything about the errors i'm running into.

There is no documentation currently. You need LLVM, Clang, nasm, rust, MozillaBuild, Visual Studio 2017 Community, Windows SDK, python2. Some of them you need to also add to PATH environment variable.

After you get everything, just do ./mach build in Waterfox source directory.

What errors have you?

I get this error:

What version of LLVM/Clang are you using and where did you get them from?

[pistasjis]

clang is version 11, i don't remember where i got them from.

[pistasjis]

oh yeah, I am using clang from Visual Studio

[pistasjis]

Nevermind, I was using Clang from mozillabuild itself. However, when I made it use the Visual Studio clang, it threw an error about the machine being x86 bit, targetting x64 but my machine is actually x64.

If it's possible to cross-compile to Windows from Linux I can definitely do that because I always get annoyed when compiling things on Windows
