How to package your own mod_auth_openid 0.9 for Ubuntu

package_mod_auth_openid.sh

#!/bin/bash

# Ubuntu version of package: http://packages.ubuntu.com/trusty/libapache2-mod-auth-openid
# FPM man page: https://github.com/jordansissel/fpm/wiki
# FPM instructions for autotools: https://github.com/jordansissel/fpm/wiki/PackageMakeInstall

# install build-time dependencies
# yes, apache2 is a build-time dependency, otherwise APXS breaks:
# "checking Apache version... configure: error: /usr/bin/apxs2 says that your apache binary lives at /usr/sbin/apache2 but that file isn't executable."
sudo aptitude -y install \
    git \
    apache2 \
    apache2-dev \
    libopkele-dev \
    libcppunit-dev \
    autoconf \
    libtool \
    ruby \
    ruby-dev

# install the FPM packaging utility
sudo gem install fpm

# check out my version of mod_auth_openid
# should default to the mysql-sessions branch
git clone https://github.com/SteelPangolin/mod_auth_openid.git
cd mod_auth_openid

# creates configure script, then runs it
./autogen.sh

# actually compile things
make

# directory for package contents to go in
mkdir pkgtmp

# APXS ignores $DESTDIR, so we can't use make install DESTDIR=... for this package
# instead, copy files manually:

# copy Apache module
mkdir -p pkgtmp/usr/lib/apache2/modules
cp src/.libs/mod_auth_openid.so pkgtmp/usr/lib/apache2/modules/

# copy table maintenance tool
mkdir -p pkgtmp/usr/bin
cp src/modauthopenid_tables pkgtmp/usr/bin/

# create Apache config for module loading
mkdir -p pkgtmp/etc/apache2/mods-available
echo "LoadModule authopenid_module /usr/lib/apache2/modules/mod_auth_openid.so" \
    > pkgtmp/etc/apache2/mods-available/authopenid.load

# set permissions for package contents
chmod -x pkgtmp/usr/lib/apache2/modules/mod_auth_openid.so
chmod -R u=rwX,go=rX pkgtmp

# create package with FPM
fpm \
    -s dir \
    -C pkgtmp \
    -t deb \
    --name libapache2-mod-auth-openid \
    --version 0.9.0 \
    --architecture native \
    --depends libc6 \
    --depends libgcc1 \
    --depends libstdc++6 \
    --depends libapr1 \
    --depends libaprutil1 \
    --depends libopkele3 \
    --depends libcurl3-gnutls \
    --depends libpcre3 \
    etc usr

# package should now exist as libapache2-mod-auth-openid_0.9.0_amd64.deb
