Here we assume you want install Concurrence for use with ‘Normal Python’ as opposed to ‘Stackless Python’. This is the easiest way to get started with Concurrence. Later you may want to try out Stackless because it delivers a bit better performance (typicaly about 10-25% faster). We will be using setup tools to install all dependencies.
Note that Linux users might need to make sure they are running as root, or prefix the commands with ‘sudo’.
First we need to install Pyrex:
Next we will install concurrence:
If might give an error: Setup script exited with error: SandboxViolation: ... This is a known problem with Pyrex, please do:
python -c "from Pyrex.Compiler import Scanning;Scanning.get_lexicon()"
And then try install concurrence again
Finally we need to install the Greenlet package:
If you run into compiler problems on Linux, this is most probably caused by missing development headers for Python and or libevent. On Ubuntu these packages can be installed using:
apt-get install python-dev apt-get install libevent-dev
If you run into compiler problems on OSX, this is most probably casued by missing libevent and or its headers
- Download latest stable release of libevent.
- Unzip and cd into the libevent directory
- Run ./configure && make
- Run sudo make install
- Try installing concurrence again
That should be it!, you should now be able to start playing with the examples
easy_install routes easy_install webob
If you use Python2.5, you might want to install ‘simplejson’ as well:
First make sure you have the source distibution of Concurrence:
svn checkout http://concurrence.googlecode.com/svn/trunk/ concurrence
The examples can be found in the examples directory and are documented on the Concurrence website at http://opensource.hyves.org/concurrence
If you want to run Concurrence on top of stackless (which is a bit faster), you will need to install Stackless Python. Download the latest stackless tarball from www.stackless.com. unpack it somewhere (/tmp/stackless), and execute the folowing commands:
UBUNTU: Make sure you have <libreadline-dev> package. Otherwise you have no history support in the python interactive shell (on ubuntu: apt-get install libreadline-dev)
We will install stackless in /opt/stackless using the prefix argument to configure. This will prevent any existing python installation from being overwritten:
UBUNTU: ./configure --prefix=/opt/stackless --with-readline --with-zlib=/usr/include make make install OSX (Leopard): ./configure --prefix=/opt/stackless --enable-framework --enable-stacklessfewerregisters --with-readline --with-zlib=/usr/include echo '#define SETPGRP_HAVE_ARG' >> pyconfig.h make make install
I always like to make a symlink to stackless for everyday usage and to differentiate it from ‘normal’ python:
ln -s /opt/stackless/bin/python2.5 /usr/bin/stackless
