How do I build this?

[K4sum1]

Making this a separate issue because I don't want to fill up a unrelated issue.

So far I've installed Mozillabuild 3.4, but not sure what else to do. ./mach bootstrap doesn't work so I just tried to ./mach build. Gave an error about not having Visual Studio 2017, so I installed it, and now I have ERROR: Cannot find the target C compiler, and I'm not sure how to fix it. It mentions mingw32, so I tried grabbing that, but I have no idea what to pick in the installer, if I even found the right installer. What do I do?

Also pinging @hawkeye116477 since he seems to have the most knowledge about this.

Just check here => https://github.com/WaterfoxCo/Waterfox-Classic/blob/classic/.github/workflows/build.yml#L60 how it's done on GitHub Actions. Besides those you may also need Windows 10 SDK. However maybe you will need to try some lower versions of depends.

I tried installing those, but I get the same error.

[hawkeye116477]

Only installing isn't enough, you may need to set environment variables and start mozilla-build shell, almost everything same as in linked URL.

[K4sum1]

I checked the environment variables, and they matched outside of mine being installed in different paths. I even rebooted since environment variables sometimes require that.

[hawkeye116477]

So check if you can execute clang or clang-cl inside mozilla-build shell. If not, then maybe try editing batch file to set variables just like it's done on GH Actions, otherwise I've no idea, I was building it long time ago and don't remember.

[K4sum1]

So I have clang in my path, I can run it with normal CMD. However I always get command not found in MozillaBuild.

[hawkeye116477]

So as I said, you need to edit that mozilla-build batch file, find line with SET "PATH= and replace (add path to every thing which it can't find).

After dealing with a few other issues and manually upgrading watchman, now I get this.

[hawkeye116477]

You need to try some older version of LLVM/Clang and maybe some other depends will also need different version if you'll still see errors. I don't remember which versions of these tools are good for Classic.

1) The issue topic seems to me to be a repetition that would be better avoided.

#issuecomment-831834241 - [Classic] Where's the build documentation? - Issue #43 - WaterfoxCo/Waterfox-Classic - GitHub

2) > I don't remember which versions of these tools are good for Classic.

#issuecomment-1319924456 - Windows action failing - Issue #173 - WaterfoxCo/Waterfox-Classic - GitHub

Eventually you can try with last good working llvm/clang version (14.0.6, scoop install [app]@[version]).

3) If the existing information is not enough to solve the issue, I think it's okay to additionally ask @MrAlex94, @buttercookie42, @aeiouaeiouaeiouaeiouaeiouaeiou or @dbsoft for the Waterfox Classic build environment recommendation to @K4sum1 and possibly others.

Kind of off-topic

Personally, I would be especially grateful if someone could implement the following missing features. * Class Fields * [#issuecomment-1854367897 - GitHub - Missing redesigned code file view on Waterfox Classic (non-e10s) - Issue #94 - martok/palefill - GitHub](https://github.com/martok/palefill/issues/94#issuecomment-1854367897) * :is() CSS pseudo-class * [Merge pull request 'Implement :is() and :where() CSS pseudo-classes' (#2110) from FranklinDM/UXP-contrib:work_css-is-where into master · 9d9d93381e - UXP - Pale Moon repositories](https://repo.palemoon.org/MoonchildProductions/UXP/commit/9d9d93381e03157413f0a18fc544afafad4fff70) * Web Components * [#1361 - Implement Google WebComponents - UXP - Pale Moon repositories](https://repo.palemoon.org/MoonchildProductions/UXP/issues/1361) As such features don't seem to be properly provided by an extension like Polly+.

Hmm, I might try getting everything I need to build Mypal68, and once or if I get that working, I try seeing if I can also build Waterfox Classic. If I still can't I'll try this, I'll look into those.

workflows are outdated and don't work properly.

You can use current clang if you can find where you need to add cflag -Wno-error=implicit-function-declaration
