Using couchdb in sagemath

For using couchdb you need to recompile the sagemath-python with ssl-support. This is quite easy:

• Download the python package e.g: python-2.6.4.p11.spkg
• wether you use the safe part (first) or do it directly (second)
• first way

  1. rename it to: python-2.6.4.p11.tar.bz2

  2. unpack it
• second way

  1. unp python-2.6.4.p11.spkg

• edit the Setup.Dist like it is explained here: http://www.webtop.com.au/blog/compiling-python-with-ssl-support-fedora-10-2009020237

This is the interesting part

   1 Now I had to modify the file Modules/Setup.dist in the Python source (mine was located in /usr/local/src/Python-2.6.1).  Change the following lines (highlighted in red).
   2 > vi Modules/Setup.dist
   3 ...
   4 
   5 206 # CSV file helper
   6 207 #_csv _csv.c
   7 208
   8 209 # Socket module helper for socket(2)
   9 210 _socket socketmodule.c
  10 211
  11 212 # Socket module helper for SSL support; you must comment out the other
  12 213 # socket line above, and possibly edit the SSL variable:
  13 214 #SSL=/usr/local/ssl
  14 215 _ssl _ssl.c \
  15 216     -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \
  16 217     -L$(SSL)/lib -lssl -lcrypto
  17 218
  18 219 # The crypt module is now disabled by default because it breaks builds
  19 220 # on many systems (where -lcrypt is needed), e.g. Linux (I believe).
  20 221 #
  21 222 # First, look at Setup.config; configure may have set this for you.
  22 223
  23 224 #crypt cryptmodule.c # -lcrypt  # crypt(3); needs -lcrypt on some systems 

• uncomment line 210 and 215-217. Maybe in your version the line numbers are different.

• pack it again with: tar -cjf python-2.6.4.p11.spkg ./python-2.6.4.p11/

• now you need to force the install in sage with: /usr/local/sage-4.7.1/sage -f python-2.6.4.p11.spkg (change it to your path!!)

== now you can install the couchdb python package ==;

• start the sagemath sh-mode: /usr/local/sage-4.7.1/sage -sh

• now there should be: (sage subshell) centre:~ root$

• here you need to do e.g just: easy_install http://pypi.python.org/packages/2.6/C/CouchDB/CouchDB-0.8-py2.6.egg#md5=b47f8fe5f0c76d7c45bf8e4805d43de4

The link for the current version you will find here: http://pypi.python.org/pypi/CouchDB

If you want to use a local couchdb-Server you will have to install it on your local machine. For debian/ubuntu do sudo apt-get install couchdb in a terminal.
