vlc refuses to compile against qtbase-opensource-src

[Benjamin Drung]

The daily builds of vlc 2.2.x refuse to compile against qtbase-opensource-src on xenial:

configure: error: "You cannot build VLC with Qt-5.5.0. You need to backport I78ef29975181ee22429c9bd4b11d96d9e68b7a9c"

Build recipe: https://code.launchpad.net/~videolan/+recipe/stable-daily.xenial
Full log: https://launchpad.net/~videolan/+archive/ubuntu/stable-daily/+build/8859183

Please backport that commit to xenial.

The patch in question is actually already backported to Ubuntu: http://anonscm.debian.org/cgit/pkg-kde/qt/qtbase.git/tree/debian/patches/set_WA_OutsideWSRange_for_native_widgets.patch?h=ubuntu

That means VLC is making a wrong assumption about it not being backported and needs to be forced to skip that error.

FTR, qtbase-opensource-src 5.5.1+dfsg-10ubuntu2 ships set_WA_OutsideWSRange_for_native_widgets.patch

I'll open an upstream bug for it.

configure.ac does only a version check:

      PKG_CHECK_EXISTS([Qt5Core >= 5.5.0 Qt5Core < 5.6.0], [
        AC_MSG_ERROR(["You cannot build VLC with Qt-5.5.0. You need to backport I78ef29975181ee22429c9bd4b11d96d9e68b7a9c"])
      ])
