I guess from some of the other output you pasted on matrix that this is the new Apple linker, which would certainly explain things.

Comment 2

[Mike Hommey [:glandium]]

Can you paste the output from clang -Wl,--help?

Hm. I have need to build ESR 115 on my Sonoma MBP, and I'm hitting this. Is there a workaround to get me going here?

build with --enable-bootstrap

(In reply to Mike Hommey [:glandium] from comment #8)

build with --enable-bootstrap

This does not fix the issue.

Homebrew performs the following change to be able to build (as of latest ESR 128):

s.sub! '"-Wl,--version"', '"-Wl,-ld_classic,--version"' if DevelopmentTools.clang_build_version >= 1500

Comment 13

[Rob Wu [:robwu]]

I'm unable to build ESR115 on macOS Sequoia, even with ./mach bootstrap.

 0:02.64 ERROR: Failed to find an adequate linker

With the patch from comment 11 (or editing -Wl,--version to -Wl,-v), it does not fail at the above step, but still fails shorty after:

*** Fix above errors and then restart with "./mach build"

... fortunately, in my case I did not really have to create a compiled build. I looked up the most recent hg revision from https://hg-edge.mozilla.org/releases/mozilla-esr115

and build as follows:

MOZ_ARTIFACT_REVISION=8a77c6bc418640a11727e9ffa6da543bcd84a8bd ./mach build

(I had to manually set the revision because after the migration from hg to git, the artifact cannot be located from a git repo without cinnabar metadata )
