Built it for the first time, on the AMD Bazzite box (`.116`, RADV 780M, Fedora 43 toolbox). The patches applied cleanly to the pinned rev and the configure got all the way through wlroots — then found three things no amount of reading would have: **1. `SPA_VIDEO_TRANSFER_SMPTE2084` does not exist on Fedora 43.** PipeWire 1.4.11's transfer-function enum stops at `ADOBERGB`: SPA grew BT2020_10 / SMPTE2084 / ARIB_STD_B67 as one later block. So the patch simply did not compile on the distro it is primarily FOR. This is the same trap punktfunk's own consumer documents and works around — `pf-capture`'s `pw_pods.rs` spells the value out as `14` for exactly this reason — and the fix is the same: spell out both colorimetry values, because the enum is wire ABI mirroring GStreamer's, not a private detail. `SPA_VIDEO_COLOR_PRIMARIES_BT2020` is present here but gets the same treatment, since its own header comment says `\since 1.6` and there is no reason to depend on that. The `PW_CHECK_VERSION(1, 0, 0)` guard was also just wrong: it tests the library version, which says nothing about which enum members a header names. It now guards only the FORMAT constants, which are what it was actually right about. **2. The build pulled in three subprojects we never ship.** gamescope's own unit tests want Catch2 **v3** (`catch2-with-main`) and Fedora ships v2, so the configure died on a test suite that is not ours to build. Also disabled: the OpenVR integration (a code path a headless capture session never enters) and the WSI layer — which would have been WORSE than wasted work, since the distro gamescope package installs that same layer and ours would have collided with it file-for-file. **3. `dnf builddep gamescope` is not sufficient.** It resolves Fedora's *packaged* gamescope, which is older than the master we pin, and misses `xorg-x11-server-Xwayland-devel` — without which wlroots fails several minutes in with a `xserver.wrap` error that names nothing useful. Documented with the symptom, so the next person recognises it in one line instead of ten minutes.
