[mythtv-users] mythbackend - undefined symbol

[John Pilkington]

I've just built and installed fc24 rpms for master-0.29-pre-345.  It 
appears that my previous build, which works, was erroneously based on 
the tarball for 0.29-pre-239.

On trying to start mythbackend in a tab in a kde konsole (which is what 
I normally do) I now get a symbol lookup error:  undefined symbol 
_ZN11MythContextC1ERK7QString

I've looked in the build log and see nothing like this.  Ideas?
