1544418 - Build error on macOS: SDK version "10.14" is unsupported. Please downgrade to version 10.13.

Status: RESOLVED FIXED

(Firefox Build System :: General, defect)

Description

[Kartikaya Gupta (email:[e-mail])]

See bug 1522931 comment 19 onwards. Spinning this out into a new bug so it can be found by mach busted. In summary, currently m-c builds are broken on macOS 10.13 with the 10.14 SDK installed.

Comment 1

[Nathan Froyd [:froydnj]]

We implemented that check because building with the 10.14 SDK results in an unusable firefox (bug 1494022), and it seemed better to yell at people earlier in the build, rather than have them launch firefox and discover that something else is busted. Does your build with the 10.14 SDK not display a black window? Because that would be an interesting datapoint.

[Kartikaya Gupta (email:[e-mail])]

I suspect that building on 10.14 with a 10.14 SDK results in the black screen, but building on 10.13 with a 10.14 SDK is ok. I'm fairly sure that's what I was building before. But I'm doing a build now with my m-c rolled back to before bug 1522931 landed to confirm.

Comment 3

[Jonathan Kew [:jfkthame]]

Yes, as per https://bugzilla.mozilla.org/show_bug.cgi?id=1522931#c20, I've been building with SDK 10.14 on my macOS 10.13 machine, and my builds run fine (no black window).

It's possible such builds would fail on 10.14, but that isn't an issue for my local development and testing.

Also as noted in https://bugzilla.mozilla.org/show_bug.cgi?id=1522931#c20, I tried the solution recommended by the error message (installing and using the 10.13 SDK), but this led to a compile failure, apparently related to IOKit headers.

And yes, with m-c at rev 43a182c1a3733010b8c95cc8c65ddfe9e0fe0fd6 it builds and runs fine on 10.13 with the 10.14 SDK.

FWIW I'm building w/ 10.14 SDK on macOS 10.14.4 and everything runs fine.

Does that mean that bug 1494022 is no longer an issue? If not, we could just remove the 10.14 check entirely.

The version check was originally added in bug 1500504, but bug 1522931 extended it to always do the check, not just when --with-macos-sdk was specified in the mozconfig. Maybe the black screen issue was fixed upstream? Or did we fix it and never close the bug?

I also am building successfully on 10.14.4 with 10.14 SDK. The only problem I've had is fixed by following the steps at https://bugzilla.mozilla.org/show_bug.cgi?id=1487552#c17

[Michael Shal [:mshal]]

:spohl, :mstange - Any objections to bumping the max supported SDK to include 10.14? Asking you two as the reporter for bug 1500504 and assignee of bug 1494022.

If you've followed those steps, you are now building with the 10.13 SDK on 10.14.

And yes, with m-c at rev 43a182c1a3733010b8c95cc8c65ddfe9e0fe0fd6 it builds and runs fine on 10.13 with the 10.14 SDK.

This will most likely not force CoreAnimation, which occurs on 10.14 when built with the 10.14 SDK. For anyone switching SDKs for a build, it might make the most sense to switch to 10.11, which is what our build system uses. Any other configuration really isn't tested and results can be unpredictable.

What I meant to convey is that I have been successfully building on 10.14.4 with the 10.14 SDK up until this bug prevented me from doing so. What I am now trying to do is downgrade to the 10.13 SDK as proposed, and see if I can still build successfully.

Build AND run? Or only build? Building always succeeded, but running this type of build used to trigger bug 1494022.

I haven't tried to build and run with the 10.14 SDK in a while and therefore can't say if this check can be removed. Maybe :mstange has done so recently.

Yes, build and run on 10.14.4 with 10.14 SDK. No black screen problems (Bug 1494022).

Note that just bumping the sdk_max_version to 10.14 gave me build errors (on my macOS 10.13 + SDK 10.14 setup). This was surprising to me. The error messages can be seen at https://bugzilla.mozilla.org/show_bug.cgi?id=1522931#c23

Building on 10.14.4 with the 10.13 SDK was successful and my built Nightly appears to be running fine.

Comment 16

[Mark Banner (:standard8)]

For me, I was running fine with the 10.14 sdk on 10.14.4 (apart from issues with --enable-warnings-as-errors which I disabled).

I hit the IOKit header issue as mentioned earlier when trying to build with 10.13 (as per the message) - I've filed that as bug 1544763.

Seems to be building fine with the 10.11 sdk so far.

For the record, this happens because prior to bug 1522931 landing, macos_sdk was false (or None or whatever) here and so the -isysroot flag would not get used. This did the The Right Thing on macOS 10.13 + SDK 10.14. With the patch from bug 1522931 plus the sdk_max_version bumped to 10.14, the -isysroot flag DOES get added, and that results in compilation errors.

I don't know what the best fix here is, but if it involves me updating to macOS 10.14 I'm happy to do that, as long as the issues with that configuration are fixed (which it sounds like they are, for some people at least).

Comment 18

[Mike Conley (:mconley) (:⚙️)]

I'm hitting this too. I followed the error message's advice, and downloaded the macOS 10.11 SDK from https://github.com/phracker/MacOSX-SDKs, and pointed my .mozconfig at it.

I got past the configure step, but now I'm hitting this:

Which... I don't really know what to do with. Is there a short-term fix I can apply to get my build working again? Maybe manually bumping this?: https://searchfox.org/mozilla-central/source/build/moz.configure/toolchain.configure#139

Comment 19

[Eric Rahm [:erahm]]

This is breaking builds for a lot of people, I'm going to suggest backing out part of bug 1522931 and bumping or max version back to 10.14.
