Installation
------------
bcolz depends on NumPy and, optionally, Numexpr. Also, if you are
going to install from sources, and a C compiler (Clang, GCC and MSVC
2008 for Python 2, and MSVC 2010 for Python 3, have been tested).
Installing from PyPI repository
===============================
Do::
$ easy_install -U bcolz
or::
$ pip install -U bcolz
Installing from conda-forge
===========================
Binaries for Linux, Mac and Windows are available for installation via conda.
Do::
$ conda install -c conda-forge bcolz
Installing Windows binaries
===========================
Unofficial Windows binaries are provided by Christoph Gohlke and can be
downloaded from:
http://www.lfd.uci.edu/~gohlke/pythonlibs/#bcolz
Using the Microsoft Python 2.7 Compiler
=======================================
As of Sept 2014 Microsoft has made a Visual C++ compiler for Python 2.7
available for download:
http://aka.ms/vcpython27
This has been made available specifically to ease the handling of Python
packages with C-extensions on Windows (installation and building wheels).
It is possible to compile bcolz with this compiler (Jan 2015), however,
you may need to use the following patch::
diff --git i/setup.py w/setup.py
index d77d37f233..b54bfd0fa1 100644

Installing from tarball sources
===============================
Go to the bcolz main directory and do the typical distutils dance::
$ python setup.py build_ext --inplace
In case you have Blosc installed as an external library you can link
with it (disregarding the included Blosc sources) in a couple of ways:
Using an environment variable::
$ BLOSC_DIR=/usr/local (or "set BLOSC_DIR=\blosc" on Win)
$ export BLOSC_DIR (not needed on Win)
$ python setup.py build_ext --inplace
Using a flag::
$ python setup.py build_ext --inplace --blosc=/usr/local
It is always nice to run the tests before installing the package::
$ PYTHONPATH=. (or "set PYTHONPATH=." on Windows)
$ export PYTHONPATH (not needed on Windows)
$ python -c"import bcolz; bcolz.test()" # add `heavy=True` if desired
And if everything runs fine, then install it via::
$ python setup.py install
Testing the installation
========================
You can always test the installation from any directory with::
$ python -c "import bcolz; bcolz.test()"
