Step 3: Build eCAP 3 Library

Warning

This article is now obsolete and no longer updated, please consider switching to Ubuntu 20.04 LTS. The following article describes how to build the latest Squid 4 on Ubuntu 20.04 LTS Build Squid 4 on Ubuntu 20.04 LTS.

Latest Squid depends on presence of eCAP adapter library on the host machine. Default libecap2 library present in Ubuntu 16 Xenial is too old. We will need to build a newer version. In order to do that run script 03_build_ecap.sh.

#!/bin/bash
if [[ $EUID -eq 0 ]]; then
   echo "This script must NOT be run as root" 1>&2
   exit 1
fi

# set ecap version
source ecap.ver

# drop ecap build folder
rm -R build/libecap

# we will be working in a subfolder make it
mkdir -p build/libecap

# decend into working directory
pushd build/libecap

# get libecap from debian stretch
wget http://http.debian.net/debian/pool/main/libe/libecap/libecap_${ECAP_PKG}.dsc
wget http://http.debian.net/debian/pool/main/libe/libecap/libecap_${ECAP_VER}.orig.tar.gz
wget http://http.debian.net/debian/pool/main/libe/libecap/libecap_${ECAP_PKG}.debian.tar.xz

# unpack the source package
dpkg-source -x libecap_${ECAP_PKG}.dsc

# build the package
cd libecap-${ECAP_VER} && dpkg-buildpackage -rfakeroot -b

# and revert
popd

ecap.ver file is just to easier manage eCAP versions in script.

#!/usr/bin/env bash

# set ecap version
ECAP_VER="1.0.1"
ECAP_PKG="${ECAP_VER}-3.2"

After build is successful, run script 04_install_ecap.sh to install the library and headers. These are needed to build Squid on the next step.

#!/bin/bash
if [[ $EUID -ne 0 ]]; then
   echo "This script must be run as root" 1>&2
   exit 1
fi

# set ecap version
source ecap.ver

# decend into working directory
pushd build/libecap

# install ecap packages
dpkg --install libecap3_${ECAP_PKG}_amd64.deb
dpkg --install libecap3-dev_${ECAP_PKG}_amd64.deb

# and revert
popd
