Apparently it gives some benefits in regards to dark mode integration, so it's probably worth doing.

Note that we're currently doing a lot of "non-standard" things, so building with the 10.14 SDK may not give us any benefits at all with respect to dark mode. There are other bugs (such as bug 1470597) that may accelerate the timeline to build with the 10.14 SDK, but dark mode may not be it.

Dialogs and different -moz-appearance values get the dark mode integration automatically. It looks like the profile selector/crash reporter already benefit from dark mode integration (with the right native textures) in my local build. There may be more, but unfortunately my build crashes so I don't know.

As far as I can tell the hardest part of this bug is to build on Linux. We need some works in cctools.
I haven't looked into this lately, so bug 1391023 comment 2 is the last I knew of what we'd need to do that.

This doesn't quite answer my question in comment 10. Also, not sure why that comment was marked private. I would need to know if all the tools necessary to cross-compile with the 10.15 SDK are available to us. In the past, we had to wait for Apple to open source the necessary tools. Do you happen to know if all the tools to cross-compile with the 10.15 SDK are available to us? If not, do you happen to know who might know? Thank you

Flags: needinfo?(hikezoe.birchill)

I am afraid I don't know. I am not an expert about Mac OS at all. The reason I got involved this is that I thought we had to build our source code which is using newer APIs introduced 10.14 SDK on our CIs with cross-compling. But it's no longer issue for me.

I think you know about Mac better than me. :)

Flags: needinfo?(hikezoe.birchill)

The question here is about cross-compilation on Linux. So if anyone on the CC list can chime in on the state of the required tools to cross-compile on Linux, it would be appreciated (Ted's status says that he's not currently active, unfortunately).

Our cctools-port copy builds with tapi now, so presumably it might be possible? You'll only know if you try...

Is there a document that would tell me how to "try" this..? Or can you walk me through the steps? This is rather unfamiliar territory for me.

I have a real 10.15 SDK, but I seem to have a more recent version than the one on GitHub and there are tons of differences. I'm not sure how we will be able to tell that the copy is pristine, unless we know exactly what version of the 10.15 SDK to compare it to.

:hiro, I see that you have tried this back in bug 1391023 comment 4 and bug 1391023 comment 7. Could you walk me through the steps to verify that we have the necessary tools to crosscompile with the 10.14 or 10.15 SDK? And assuming that this is successful, do you know what I need to do to push a new SDK to the build machines? Thank you!

Flags: needinfo?(hikezoe.birchill)

I actually couldn't recall what I did before, so I tried it again.

  1. Clone https://github.com/tpoechtrager/apple-libtapi
  2. pushd apple-libtapi && INSTALLPREFIX=$HOME/cctools ./build.sh && ./install.sh && popd
  3. Clone https://github.com/tpoechtrager/cctools-port (we might need to use a specific revision)
  4. pushd cctools-port/cctools && ./autogen.sh && ./configure --prefix=$HOME/cctools --with-libtapi=$HOME/cctools --target=x86_64-apple-darwin --enable-tapi-support --with-libtapi=$HOME/cctools --enable-lto-support && make install
  5. ln -sf $HOME/cctools/bin/x86_64-apple-darwin-ld $HOME/cctools/bin/ld64 (this might be unnecessary)
  6. Clone https://github.com/phracker/MacOSX-SDKs
  7. rustup target add x86_64-apple-darwin
  8. build firefox with below .mozconfig

.mozconfig

ac_add_options --target=x86_64-apple-darwin
ac_add_options --with-macos-sdk=$HOME/MacOSX-SDKs/MacOSX10.14.sdk
mk_add_options "export PATH=$PATH:$HOME/cctools/bin"

Now building seems to start working on my local Linux box (but it still takes a lot of times on toolkit/crashreporter/google-breakpad/src/tools/mac/dump_syms/dump_syms now, I mean the build hasn't finished yet).

Anyways, as glandium said in comment 16, cctools on CIs has been updated so it seems to me that all we have to do is to upload the new MacOSX tar ball to an appropriate place and use it, I don't know where the place is though, the way to generate the tar ball is well documented.

A fun fact I noticed is that the SDK 10.14 in the repo was uploaded by kats, so it is a resonable one I believe.

This sounds quite familiar. I feel like I saw this when building with the 10.14 SDK locally back when I was working on bug 1549052 and I must have found some way to fix it. I don't recall what it was but if you provide a bit more of the error message I might be able to help.

We'd need more context on the error (like what file it happened in) and if possible, the preprocessed source for the file to figure out what's going on (make file.i in the directory containing file.mm or similar). That symbol should be provided by the runtime libraries that we're linking in.

We may want to check if building with the 10.15 SDK is possible. If so, I'd be happy to upload that and for us to switch straight to the 10.15 SDK on our build system.

I can try doing that build locally on macOS, I have a 10.15 SDK in /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/. Don't know if that will automatically make things work when cross-compiling from Linux though.

Ah, so your linker errors are coming from the @available checks in the code, e.g. this one and the blame for that led me to bug 1564216 which has this relevant comment but I haven't read through the rest of the bug in detail. Presumably people who were involved that bug (glandium, spohl, etc.) know better what's going on there.

My build with the 10.15 SDK failed with this:

Are you saying that a regular build on macOS with the 10.15 SDK is failing for you? Those builds should succeed as of bug 1583854, and they do work on my end.

Is there a way to get the 10.15 SDK into tooltool so that we can use try to test crosscompilation?

I had a conversation with :froydnj the other day and here is what was said as being necessary to start building with the 10.15 SDK on our build system:

you need to upload the new SDK into tooltool (https://mozilla-releng.net/tooltool/) and then modify the cross-*.manifest files in https://searchfox.org/mozilla-central/source/browser/config/tooltool-manifests/macosx64 to point at the new SDK

The one thing we haven't been able to figure out was how to upload the new SDK into tooltool. Tom, would you know?

Yeah, it's a regular build on macOS that's failing. I can file a bug for that if we care enough to fix it. It might be something in my mozconfig. Unless we're building with that in automation I'm not expecting it to stay working in the long term though.

The goal is to move to the most recent version of the SDK that we can build with, i.e. hopefully 10.15. In the past we weren't always able to switch to the most recent version of the SDK due to some tools not having been open-sourced yet, which is what we're trying to figure out here. If I had to make a guess I'd say it is most likely something in your mozconfig that is causing the build to fail at the moment.

Ok, I filed bug 1624895 for the failure I was seeing.

I don't think we are currently blocked by the SDK version. We need to define some constants locally, it's not ideal, but not terrible.

Time is ticking for this issue to become a real blocker for the entire macOS platform. Due to Apple's switch to Arm on Mac, it is foreseeable that macOS binaries need to be compiled with macOS 10.16 SDK presumably in 2022. Right now Rosetta 2 makes it possible to run old x86 binaries on Arm Macs. However Apple already announced a 2 year transition. So it can be expected that Rosetta 2 (like Rosetta 1) will be removed at the end of that process.

I am not sure if anyone already tried cross compilation with the macOS 10.16 SDK at all and how bad it is to fix the compiler and linker errors with a Linux cross compiler. If it is really a lot of work to get it working, then another option would be running either Catalina or Big Sur e.g. in QEMU and using native Xcode to bake the Firefox binary. That would also make it more easy to keep track with latest macOS SDKs in future.

Firefox 84 is already native on Apple Silicon and is built with the 11.0 SDK. There is no benefit to upgrading the SDK for Intel, so the SDK is still on 10.11/12 there.

In light of Big Sur's UI changes especially, having an actually native dark mode and not just a chrome dark theme is one benefit. macOS elements such as right click menus, unstyles drop-downs or input boxes, buttons, etc., all remain light in the browser despite the OS being set to dark mode and the browser being set to dark mode. It's easy to mistake it as a bug (that's how I've ended up here).
