Re: Circular dependency with mariadb el7

Hello Stephen,

I had a look at mariadb-server to see where we can get mysql-server from 
. Here the picture is very messy . In fc20 mariadb-server, as delivered 
does in fact provide mysql-server , however in el7 that is not the case 
. The RHEL source of mariadb-server for Centos/Scientific 7 re-branding 
does not have the mysql-server there . So we have a few possibilities 
all of them a pain , because build process of mythtv for Fedora will be 
different from that of Centos . For Centos we will need to have 
mariadb-galera-server , unless we re-package/re-compile the fedora srpm 
of mariadb-server for Centos . If that is the case you will then need to 
host this modified version for Centos users . Other possibility for 
Centos users is to tie in the mariadb-galera project repo as a 
dependency for mythtv , and have it pull from there .


Best Regards

Milorad
