For those who are interested to have PyROOT running on their NIKHEF linux
 
desktop, here is my recipe:
 
  
Download python: http://www.python.org/ftp/python/2.3.5/Python-2.3.5.tgz <br>
+
====AFS access (not necessary for workshop)====
tar xvzf Python-2.3.5.tgz<br>
 
cd Python-2.3.5<br>
 
mkdir ../python_dir
 
<br>
 
1. Install it in your home dir(for example) by compiling it with options:<br>
 
<br>
 
./configure --enable-shared --prefix=$HOME/python_dir <br>
 
make <br>
 
make install <br>
 
  
2. Add in your .tcshrc file the following lines:<br>
+
If you need access to CERN AFS areas,
 
+
<pre>
setenv ROOTSYS /project/bfys/root/root-5.10.00 <br>
+
klog user@CERN.CH
setenv PATH ${ROOTSYS}/bin:${PATH} <br>
+
</pre>
setenv LD_LIBRARY_PATH <br>
+
Where user is your CERN AFS username. Note the '''UPPER CASE''' for the domain name.
 
+
Be careful: '''Never do: ls /opt/ !! (It could start caching all atlas software...)'''.
setenv PYTHONDIR $HOME/python_dir/lib/python2.3 <br>
 
setenv PYTHONPATH $HOME/python_dir/lib/python2.3 <br>
 
setenv LD_LIBRARY_PATH ${ROOTSYS}/lib:${PYTHONDIR}:${LD_LIBRARY_PATH} <br>
 
setenv PYTHONPATH ${ROOTSYS}/lib/:${PYTHONPATH} <br>
 
 
 
3. Then, the last thing one should do is: <br>
 
cd $HOME/python_dir/lib/python2.3 <br>
 
ln -s  $HOME/python_dir/lib/libpython2.3.so.1.0 libpython2.3.so.1.0
 
 
 
4. Try it:<br>
 
$HOME/python_dir/bin/python <br>
 
>>> import ROOT <br>
 
 
 
5. If you don't get any strange warnings or errors, then everything is working ... :) <br>

AFS access (not necessary for workshop)

If you need access to CERN AFS areas,

klog user@CERN.CH

Where user is your CERN AFS username. Note the UPPER CASE for the domain name. Be careful: Never do: ls /opt/ !! (It could start caching all atlas software...).
