Please refrain from abusing the flagging of a package as out of date for build issues. This is not what it is supposed to be used for.

I automatically get notified of comments to this package. I do not need to be notified of whatever build problems occur (whether they are an individual's problems or the actual package's problems) twice, and not via flagging it out of date.

Issues with this package can also be reported at https://codeberg.org/librewolf/issues/issues (as it is also maintained there, at https://codeberg.org/librewolf/arch, too).

@xiota thanks for your comment. I got it right, just asked about it wrong, :) If I wanted to try PGO with xvfb, then I need both variables set to true, and what I did was just that:

  3 # run pgo build or not; with X(vfb) or wayland
  4 : ${_build_profiled:=true}
  5 : ${_build_profiled_xvfb:=true}

So all good, :)

@ToneyFox, PGO requires some sort of runtime environment to perform the [dynamic] profiling, see PGO. And those PGO depencies are chosen depending on:

if [[ "${_build_profiled}" == "true" ]]; then
  if [[ "${_build_profiled_xvfb}" == "true" ]]; then
    makedepends+=(
      xorg-server-xvfb
    )
  else
    makedepends+=(
      weston
      xorg-xwayland
      wlheadless-run # aur/xwayland-run-git
    )
  fi
fi

I found the PKGBUILD very useful, but needs manual intervention if you don't want the default. I didn't want to profile on top of wayland, so I chose the xvfb variable to true to profile on top of x11 stuff. Both false is also valid and there's no additional make dependency for PGO.

Make dependencies are dependencies. XWayland is quite obviously not needed to build the package, not sure how anyone could believe it potentially is

xiota commented on 2025-07-08 17:35 (UTC)

xorg-xwayland is not a depends. It's a makedep that was required for profiling and not worth the time to test whether it's still strictly required.

ToneyFox commented on 2025-07-08 16:30 (UTC)

Why does this depend on XWayland? That should be optional

xiota commented on 2025-07-08 00:57 (UTC)

_build_profiled controls whether package is built with PGO (profile guided optimization; 20% performance boost on benchmarks in exchange for 3x build time). If set to anything but "true", package will be built without PGO.

_build_profiled_xvfb controls whether the profiling environment is Xvfb or Weston. If anything but "true", Weston is used. I haven't seen any significant performance difference.

I'd use the default, unless profiling fails. Then try with Xvfb. If that still fails, try with PGO disabled.

je-vv commented on 2025-07-07 18:07 (UTC)

@lsf if using _build_profiled_xvfb:=true rather than _build_profiled:=true? does it mean Librewolf would only be optimized for X11? Meaning if one needs support for both, then one should have both variables in true? I built it fine on clean chroot (I don't even remember how long it took on the fastest box I have), but with the xvfb variable set to true and the other profiled variable set to false. I guess this means it's optimized just for X11, is that it?

I get what pgo build means (actually PGO), but I'm not clear if it means we can only optimize for GUI targets and not Librewolf independently of the target. Sorry if this has been answered before.

Thanks !

My issue appears to be a malformed call to rustc --create-name firefox_on_glean during the make process. An embed flag pasted as "-Cembed-bitcode=yes" instead of "-C embed-bitcode=yes" which results in a process kill. I confirmed by running the full command in the source directory after build failure. Any thoughts to correct this?

Successfully built this package a moment ago in a clean chroot.

Users with potential OOM issues... Try adding following to beginning of build() function:

# calculate core usage
local _mem=$(awk '/MemFree/ { print int($2/1024/1024) }' /proc/meminfo)
local _nproc=$(nproc)
local _cores=$((_mem < _nproc ? _mem - 1 : _nproc - 1))

printf '\nFree RAM: %s\nCores: %s\nUsing: %s\n\n' "$_mem" "$_nproc" "$_cores"
export MOZ_PARALLEL_BUILD=${_cores:-4}

@hugeblank That looks like a Rust + LTO type problem, but this package already has !lto in options array.

@skdoosh99 Those types of Gdk warnings are common across all GTK apps. They're most likely occurring during profiling. Probably they're safe to ignore. If they bother you enough, build with PGO disabled (but the browser will be slower).
