= Building RPMs with Mock = 

I'll try to write down what I need to do to set-up a simple rpm build system using mock, whereby some packages have dependencies on my own builds.
The build system I'm using is CentOS 7.

== Requirements for the build system ==

{{{
yum install mock createrepo yum-utils
}}}

Create the following directories to allow inspection and modification of RPM packages
{{{
mkdir -p ~/rpm/BUILD ~/rpm/RPMS ~/rpm/SOURCES ~/rpm/SPECS ~/rpm/SRPMS
}}}

Create a ~/.rpmmacros file with the following content
{{{
%HOME       %{expand:%%(cd; pwd)}
%_topdir    %{HOME}/rpm
}}}
Any source rpm you now install (as regular user) will end up under $HOME/rpm/*

Generate a GPG signing key:
{{{
gpg --gen-key
}}}
follow the instructions

{{{
gpg --export -a 'Jorrit Jorritsma' > ~/RPM-GPG-KEY-jorrit
}}}

Import your public key to your RPM DB
{{{
sudo rpm --import RPM-GPG-KEY-jorrit
}}}

Add the following to your ~/.rpmmacros file
{{{
%_signature gpg
%_gpg_path ~/.gnupg
%_gpg_name Jorrit Jorritsma
%_gpgbin /usr/bin/gpg
}}}

Singing of packages can now be done with:
{{{
rpm --addsign *.rpm
}}}

Create a rpm repository under your web server:
{{{
sudo mkdir -p /var/www/html/repos
sudo chown jorrit. /var/www/html/repos
mkdir /var/www/html/repos/x86_64
createrepo /var/www/html/repo/x86_64
}}}

Add your own repo to your mock config for the target build (e.g. /etc/mock/epel-7-x86_64.cfg)
{{{
[jj]
name=jj
baseurl=http://centos7.fritz.box/repo/x86_64/
gpgcheck=0
skip_if_unavailable=False
}}}

== get the src rpms ==

{{{
mkdir ~/asterisk
cd asterisk
wget -r --no-parent -A *.src.rpm https://ast.tucny.com/repo/
}}}


== Build the packages ==
move to the package download location
{{{
cd asterisk/ast.tucny.com/repo/asterisk-common/el7/SRPMS
}}}

Build
{{{
