The reason for the required upgrade is because qt4 is required for the

It would be interesting if we could get a decent alternate interface
without qt for the 2.x version of vlc.

Just so you know, I don't have qt4 on either system. I built 2.2.3 with
qt5.6 and gcc5.3.
Paul posted about this in May, (2.2.3 using the systemd book) - at
that time he had to use clang to build it. I replied noting that
gcc-5 worked for me.
I think there were other comments in a different|earlier thread, and
indeed ISTR at least one person could not build without qt4 (perhaps
a fuller set of dependencies than I was using).
But the book had been changed by the time I did my first (so far,
only) build with gcc6 so I've not tried that with the old release.

Ken, I ended up getting it to build with gcc5.3 instead of clang by
removing the CXX="g++ -std=c++11" flag from the book commands. Here are
the book commands (r17455):
sed -i '/seems to be moved/s/^/#/' autotools/ltmain.sh
patch -Np1 -i ../vlc-2.2.3-ffmpeg3-1.patch &&
CXX="g++ -std=c++11" \
CFLAGS="-DLUA_COMPAT_5_1" \
OPENCV_LIBS="-L/usr/share/OpenCV" \
./configure --prefix=/usr &&
make
Like I said, I removed the CXX flag for it to work with gcc5.3 / qt5.6.
I was told (by Bruce, I think) that it is definitely required for gcc6.
I tried using the following to build on my gcc6 system but it is not
working.
sed -i '/seems to be moved/s/^/#/' autotools/ltmain.sh
patch -Np1 -i ../vlc-2.2.3-ffmpeg3-1.patch &&
CXX="g++ -std=c++11" \
CFLAGS="-DLUA_COMPAT_5_1" \
./configure --prefix=/usr &&
make

Ok, I found a patch at openSUSE and got 2.2.3, 2.2.4 and 2.2.5(latest
from git stable) to build with qt5.7 and gcc6.1. Here is a links to the
patch:
Description: https://build.opensuse.org/request/show/397726
Patch:
https://build.opensuse.org/package/view_file/openSUSE:Factory/vlc/vlc-gcc6-buildfixes.patch?rev=adf9201abc61f54a7c1e192019056f48
Here is how I built:
sed -i '/seems to be moved/s/^/#/' autotools/ltmain.sh &&
patch -Np1 -i ../vlc-2.2.3-ffmpeg3-1.patch &&
patch -Np1 -i ../vlc-gcc-6-buildfixes.patch &&
CFLAGS="-DLUA_COMPAT_5_1" \
./configure --prefix=/usr --disable-atmo &&
make
As root user:
make docdir=/usr/share/doc/vlc-2.2.5 install
I only installed and tested 2.2.5 but I built the other 2 to see if they
would build with the same patches, and they did. Apparently the new
patch will break a build with gcc5, but I haven't tested that.
With the 2.2.x versions my DVDs play correctly and all the mpeg-2 files
that were not playing correctly now work. That is the extent of the
testing I did.
