MythTV 0.28.1 and 29.0 fail to build with Qt 5.10

[sandalle@…]

I've tried both mythtv 0.28.1 and 29.0 with Qt 5.10.0. 0.28.1 built fine with Qt 5.9.3.

Building in dir: /usr/src/mythtv-fixes-29
mythtv    29.0

found qmake at /opt/qt5/bin/qmake but version failed
got version:  QMake version 3.1 Using Qt version 5.10.0 in /opt/qt5/lib
qmake for Qt5.2 or newer not found.\nPlease specify the correct qmake with --qmake=

If you think configure made a mistake, make sure that you are using the latest
version of MythTV from git.  If the latest version fails, report the problem to the
mythtv-dev@mythtv.org mailing list or IRC #mythtv on irc.freenode.net
Include the log file "config.ep" produced by configure as this will help solve the problem.

$ /opt/qt5/bin/qmake --version

The OP should try the patches from #13122 and report the results in that ticket.

I tried the patches qt510-configure-v2.patch, qt510-libs.patch, qt510-plugins.patch, and qt510-programs.patch from ​https://code.mythtv.org/trac/ticket/13122 and MythTV 29.1 now gets further along the compile path, but gives a new error

Errors linking to mangled (decorated) names often indicates that one did not do a make clean and make distclean before building, or that some older library is being incorrectly referenced.

Yep, but I started with a brand new build directory (wiped the old one away first). :) I don't know which library(ies) it's trying to reference, but if you do then I can provide the version(s) I have installed.

You need xrandr enabled. It's a bug.

Installing and enabling xrandr (along with the above mentioned patches for Qt 5.10) allowed the compile to complete successfully, thanks! :)
