1769070 - Building ESR91 with a bootstrap from mozilla-central (RockyLinux) no longer works

Status: NEW

(Firefox Build System :: Bootstrap Configuration, defect, P3)

Description

[Alex Vincent [:WeirdAl]]

Steps to reproduce:

• Use Rocky Linux 8.5 (we used a Dockerfile)

hg clone https://hg.mozilla.org/mozilla-unified`
cd mozilla-unified
hg up central
./mach bootstrap
hg up esr91
./mach create-build-environment # still required on esr91, not for central
./mach configure
./mach build

Notes:

• Building central on RockyLinux 8.5 works.
• This was working until about one month ago, when I last attempted to do our custom build.
  • I think bug 1758780 caused this because I specifically noticed seeing Clang 14 in the build log, whereas previously I'd seen Clang 13.
• Building on Fedora 35 works for both esr91 and central.
  • pkgs.org says RockyLinux 8.5 has Clang 12 available to it, while Fedora 35 has Clang 13.
  • Notably, Fedora 36 has Clang 14, and was just released. (I haven't upgraded to Fedora 36 yet.)

Putting together a Dockerfile to run this via Podman will take a while. I have an unrelated bustage running Podman at the moment.

Set release status flags based on info from the regressing bug 1758780

:glandium, since you are the author of the regressor, bug 1758780, could you take a look?

I have a regression range. Bootstrapping from revision 9841eb065 allowed us to build Firefox 91.8 on RockyLinux 8.5.

Presumably, if you:

• run mach configure on central
• switch to esr91
• add ac_add_options --with-sysroot=$HOME/.mozbuild/sysroot-x86_64-linux-gnu to your mozconfig
• mach build
  it should work.

If that's the case, then presumably something in the system headers on your distro is fishy.
