How to install a python library manually

Question

I built quickfix engine  http   www quickfixengine org   for one of my tasks and also built in python support for it   Unfortunately this is a multi user env and I dont have access to the python installation path  Thus the make install command tries to copy over the files and fails  I managed to comment out the two lines where it tries to do that and the make install completed  Since I cannot put the files there  where can I put the  so file created   And how do I let python know that it is there  I looked at python org documentation but it only describes the process for setup py installations   Also I tried putting the path for the  so in  sys path  that didnt work  And is there any documents about the anatomy of a python package  Thanks

You need to install it in a directory in your home folder  and somehow manipulate the PYTHONPATH so that directory is included    The best and easiest is to use virtualenv  But that requires installation  causing a catch 22     But check if virtualenv is installed  If it is installed you can do this     cd  tmp   virtualenv foo   cd foo     bin python   Then you can just run the installation as usual  with  tmp foo python setup py install   Obviously you need to make the virtual environment in your a folder in your home directory  not in  tmp foo        If there is no virtualenv  you can install your own local Python  But that may not be allowed either  Then you can install the package in a local directory for packages     wget http   pypi python org packages source s six six-1 0b1 tar gz md5 cbfcc64af1f27162a6a6b5510e262c9d   tar xvf six-1 0b1 tar gz    cd six-1 0b1    pythonX X setup py   install --install-dir  tmp frotz   Now you need to add  tmp frotz pythonX X site-packages to your PYTHONPATH  and you should be up and running

I m going to assume compiling the QuickFix package does not produce a setup py file  but rather only compiles the Python bindings and relies on make install to put them in the appropriate place   In this case  a quick and dirty fix is to compile the QuickFix source  locate the Python extension modules  you indicated on your system these end with a  so extension   and add that directory to your PYTHONPATH environmental variable e g   add  export PYTHONPATH   path to python extensions PYTHONPATH   or similar line in your shell configuration file   A more robust solution would include making sure to compile with   configure --prefix  HOME  local  Assuming QuickFix knows to put the Python files in the appropriate site-packages  when you do make install  it should install the files to    local lib pythonX Y site-packages  which  for Python 2 6   should already be on your Python path as the per-user site-packages directory   If  on the other hand  it did provide a setup py file  simply run  python setup py install --user   for Python 2 6
