Bug 225310 – [Stable][WPE] 2.32 build Error with ENABLE_VIDEO=OFF/ENABLE_VIDEO_TRACK=OFF

• Component: WPE WebKit
• Status: RESOLVED FIXED

[Bastian Krause]

I'm building wpewebkit 2.32.0 via meta-webkit@4cedcb6 (top of main branch) with

  PACKAGECONFIG_remove = "video"

That means adding

  -DENABLE_VIDEO=OFF -DENABLE_VIDEO_TRACK=OFF

leads to these build failures:

The ENABLE_VIDEO_TRACK CMake option was removed BTW. It is implied by VIDEO now.

[Philippe Normand]

This code was heavily updated in ToT. I don't see how the VIDEO=OFF build would fail there. Someone will need to fix this specific issue in the stable branch.

Backporting the fix from bug #225316 to the 2.32 release branch fixes
the build with ENABLE_VIDEO=OFF.

But bug 225316 doesn't fix any of that ^^^
I'm confused now :)

The fix from bug #225316 was definitely needed for ENABLE_VIDEO=OFF,
maybe the reporter has other build options enabled that affect the
outcome. My test build was a clean done with:

  % CC=clang CXX=clang++ cmake -GNinja -DPORT=WPE \
      -DCMAKE_BUILD_TYPE=Release -DENABLE_VIDEO=OFF -S. \
      -Bbuild-wpe 
  % ninja -C build-wpe

In my case I am working on top of the release branch, which *also* has
a backport of the fix for bug #224198 — both are needed.

I went ahead and merged the fix from bug #225316 as r276977 in the
release branch; this issue will be gone in 2.32.1 which will be released
later this week :)

Awesome, thanks!
