Thanks for reporting it, I have pushed a wine-5.0.5-rc1 (d313cfa4542545286cbdf6583d88e418f0de8d57) to. https://github.com/mstefani/wine-stable/tree/oldstable
The only commit is the revert of that patch.
I'll wait for a few days if another brown paper bugs pops up. But do not plan to cherry pick any other patch.
bye michael
Configuring with --without-v4l2 does not trigger this; it really is about the presence of the header.
The failure mode is
In file included from v4l.c:60: v4l.c: In function 'qcap_driver_destroy': ../../include/wine/debug.h:485:56: error: '__wine_dbch___default' undeclared (first use in this function) : v4l.c:602:5: note: in expansion of macro 'ERR' 602 | ERR("v4l absent: shouldn't be called\n"); \ | ^~~ v4l.c:607:5: note: in expansion of macro 'FAIL_WITH_ERR' 607 | FAIL_WITH_ERR; | ^~~~~~~~~~~~~
and the straightforward fix is simply reverting this patch.
