Ubuntu – How to install libxml2-dev (32-bit) package on a 64-bit Ubuntu (11.10)

32-bitdevelopmentinstallationpackage-management

I want to run an binary for a 32-bit application which is dynaically linked to the libxml2 on a 64-bit Ubuntu (11.10). I have found and installed 32-bit libraries for most of the other libraries used, however I cannot find a package to install all 32-bit version of libxml2-dev.
What packages do I have to install in order to make it run?

starting the application will lead to the following error libxml2.so.2: wrong ELF class: ELFCLASS64

I succeeded to install a 32 bit version of zlib in /ust/lib32 but I cannot find a 32 bit version of libxml2.

The synaptic package manager list a libxml2-dev:i386 package. However since this eants to uninstall almost all installed packages I assume that this is for a pure 64 bit Linix

Any help?

I came across another way of having lib32 version of libxml2.so installed on 64-bit Ubuntu (12.04) - installing Adobe Reader. It's one of popular applications that most of people would need, so it will make you feel a bit more comfortable than obtaining libxml2 by doing something else.

sudo apt-add-repository "deb http://archive.canonical.com/ $(lsb_release -sc) partner"
sudo apt-get update
sudo apt-get install acroread

If you open Synaptic and focus on any installed package then click "Properties" button, you can see dialog with "Installed Files" tab.

So netcdf libraries are in /usr/lib/ and include files in /usr/include if you installed libnetcdf-dev through packaging system

How to Detect Architecture of a .deb Package

Create a script, in my example foo

#!/bin/bash

# Create a temporary folder in /tmp
dir=$(mktemp -d)

# Extract the deb file
dpkg -x "$1" "$dir"

printf "\n%s\n\n" "$1"

# Show the package architecture information
dpkg --info $1 | \
    awk '/Architecture/ {printf "defined dpkg architecture is:\t%s\n", $2}'

# Show the executable format via find and awk for ELF
find $dir -type f -exec file -b {} \; | \
        sort -u | \
        awk '/ELF/ {printf "executable format is: \t\t%s\n", $0}'

rm -rf "$dir"

exit 0

Usage

./foo <deb_file>

Example

% ./foo qtox_1.1\~git20150707.cfeeb03-97_i386.deb

qtox_1.1~git20150707.cfeeb03-97_i386.deb

defined dpkg architecture is:   i386
executable format is :          ELF 64-bit LSB executable, x86-64, version 1 (GNU/Linux), statically linked, stripped
