Compile ejabberd v14 RPM on CentOS 7

At the time of writing there was no ejabberd RPM for EL7/CentOS7. The strategy was to take the version from Fedora 22 (rawhide) and generate a binary RPM. The issues encourntered related to compiling and packaging the documentation:

  1. EL7 doesn't have a 'hevea' package (easily compiled)
  2. EL7 doesn't have a 'texlive-comment' package

 

RPMBuild Prerequisites

Install EPEL repository (for  erlang) and compilation dependencies:

# rpm -Uvh http://download.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-2.noarch.rpm
# yum install rpm-build expat-devel openssl-devel pam-devel libyaml-devel erlang erlang-rebar git autoconf automake gcc gcc-c++

 

Build

Take the the standard Fedora package and apply the following two fixes/patches:

  1. add a patch file to Makefile to handle no install documentation when it isn't built
  2. patch the spec file to add the patch above and change the docs directory
$ wget http://mirror.as24220.net/pub/fedora/linux/development/rawhide/source/SRPMS/e/ejabberd-14.07-6.fc22.src.rpm
$ rpm -ivh ejabberd-14.07-6.fc22.src.rpm
$ ... apply fixes...
$ rpmbuild -ba ~/rpmbuild/SPECS/ejabberd.spec

Install

To install the binary RPM:

# yum install http://files.lucidsolutions.co.nz/linux/centos/ejabberd-el7/ejabberd-14.07-6.el7.centos.x86_64.rpm

Hevea

The hevea RPM from Fedora was built but the 'texlive-comment' dependency was still unresolved.

# yum install 'tex(latex)' ocaml 
$ wget http://mirror.as24220.net/pub/fedora/linux/development/rawhide/source/SRPMS/h/hevea-2.18-1.fc22.src.rpm
$ rpmbuild --rebuild hevea-2.18-1.fc22.src.rpm
# yum localinstall ~build/rpmbuild/RPMS/x86_64/hevea-2.18-1.el7.centos.x86_64.rpm
