Building Python EGGs in Batch

While working with different versions of python you deal with libraries that comes with source code and doesn't provide a compiled python egg file.

Method1: Offline

Here is a script that develops eggs per python version you have installed for all packages found in lib directory (you must create that directory at the same place where the script below and drop downloaded source distribution archives in).

#!/bin/sh

rm -rf eggs
mkdir eggs
for p in /usr/local/bin/python?.?
do
    echo -n $p
    rm -rf env/
    virtualenv --no-site-packages --python=$p -q env > /dev/null 2>/dev/null
    echo -n .
    env/bin/easy_install -i lib -U -O2 -z distribute > /dev/null 2>/dev/null
    for f in lib/*  # packages to build
    do
        echo -n .
        env/bin/easy_install -i lib -O2 -z $f > /dev/null 2>/dev/null
    done
    cp env/lib/python*.*/site-packages/*.egg eggs/ 2>/dev/null
    echo done
done
rm -rf env/
rm -f eggs/setuptools* eggs/distribute*

Run script with:

./sh make_eggs.sh

Python eggs are now in eggs directory.

Method2: Online

In this case the script relies on internet connection and downloads sources right from pypi.

#!/bin/sh

rm -rf eggs
mkdir eggs
for p in /usr/local/bin/python?.?
do
    echo -n $p
    rm -rf env/
    virtualenv --no-site-packages --python=$p -q env > /dev/null 2>/dev/null
    echo -n .
    env/bin/easy_install -U -O2 -z distribute > /dev/null 2>/dev/null
    for f in $@
    do
        echo -n .
        env/bin/easy_install -O2 -z $f > /dev/null 2>/dev/null
    done
    cp env/lib/python*.*/site-packages/*.egg eggs/ 2>/dev/null
    echo done
done
rm -rf env/
rm -f eggs/setuptools* eggs/distribute*

Run script by passing packages you want to build:

./sh make_eggs.sh pycrypto lxml

Python eggs are now in eggs directory.
