[mythtv-users] rpm build of master for el7: fails to build plugins

[John Pilkington]

Hi:  This post is mainly for Gary.  el7 again!!

I have a successful build of fc27.x86_64.rpms for master from a few days 
ago, using this script as is.

https://github.com/garybuhrmaster/packaging/blob/master/MythTV/rpm/README

Yesterday I tried to build for el7 (CentOS 7).  The MythTV rpms built ok 
but the plugins failed.   It looks as if the special measures taken to 
get a new-enough version of libvpx from COPR haven't worked for plugins, 
although the correct packages were loaded during the MythTV build.

The command line I used, on the fc27 box, was

  ./BUILD_MYTHTV_RPMS -r build_cfgs/centos-7-x86_64-rpmfusion_free.cfg 
master

although the intended target system is running Scientific Linux 7x (ie 
7.5).  I don't think the build system knows that, and I hope it won't 
affect installation when a build eventually works.

The SL7 box has been running V30-Pre-11d42, but with vpx disabled in the 
build, for several weeks.  TTBOMK I don't need it.

Thanks,

John P
