I have not looked at the most recent proposals
for the mockchain patch, but for EL7, that is
likely a path not worth going down, since
the issue is with the new capability to include
other mock configs, and EL does not use that
(only Fedora).  Sorry to lead you down that path.
Just ignore that (for your use case).

And while checking things out, I noticed that
I used features in my scripts only available in
git released around 5 years ago (and EL lags
significantly (5 yrs? come on!)) so I made some
minor changes in my scripts to support the
old/obsolete git that EL7 provides.  In addition,
I presumed dnf was available (but EL7 is limited
to yum), so I added in some code to test for that
condition.  So pull the latest packaging repo code
to get my adjustments (I do not really consider them
as fixes, but tolerance of lack of RH progress).

So this is a (proposed, not fully tested)
set of instructions for building on EL7
for EL7:


--- Get some needed toolchains (this is the only
--- command you should need root for)

yum install git rpmdevtools mock yum-utils

--- you will need to add yourself to the
--- the mock group if you are not already
--- in it (and then refresh your group membership)


--- And one time if you have not already done so:

git clone https://github.com/garybuhrmaster/packaging.git

--- Read the README in the packaging/MythTV/rpm directory

--- Repeat the following sequence as necessary for every rebuild
--- Typically the git pull will pull in nothing, but just in case
--- something does get updated....  You can specify specific
--- commits if you want to, but I typically just rebuild the
--- latest from a branch (fixes/29 in this case), or master
--- (depending on what I am targeting.  The build (as you
--- know) takes a long time depending on the usual variables.

cd packaging/MythTV/rpm

git pull

./BUILD_MYTHTV_RPMS -r build_cfgs/centos-7-x86_64-rpmfusion_free.cfg fixes/29

--- Note that the EPEL/RPMFusion repos are sometimes

--- I have sometimes had to retry the build half a dozen
