[mod_python] A newbie question

Karl, Graham,
I have no problem with installing mod_python by using rpm (httpd and 
python) on Linux AS 4. But, I would like to install Apache 2.0.54 or 
2.2.2, Python 2.4 and mod_python 3.2.8 with source codes. The following 
output of "make install" bothers me because it does not create 
mod_python.so at /usr/local/apache/module. In fact, it does not create 
mod_python.so anywhere at all. 

I found /usr/local/src/mod_python-3.2.8/src/mod_python.so is a link 
/usr/local/src/mod_python-3.2.8/src/mod_python.so -> .libs/mod_python.so. 
Under  /usr/local/src/mod_python-3.2.8/src/.libs/mod_python.so there is no 
mod_python.so at all. I appreciate it if someone has a solution to fix it.

Now su and make install
  (or, if you only want to perform a partial install,
   you can use make install_dso and make install_py_lib)

Performing DSO installation.

/usr/bin/install -c -d /usr/local/apache/modules
/usr/bin/install -c src/mod_python.so /usr/local/apache/modules
/usr/bin/install: cannot stat `src/mod_python.so': No such file or

RE: [mod_python] A newbie question

Initial thought.  To compile and install 3.2.8, I believe needs flex 
2.5.33 or newer.  RHN has flex 2.5.4.  you will need to make sure that 
this is current.  I would suggest when using the .configure, that options 
for flex, python, and apxs be fully specified to insure that you know 
which versions have be used to build mod_python.
It may be easier to start with what RHN provides for their servers.  ES 
packages should work on AS.  The latest released for ES is python 
2.3.4-14.x and mod_python 3.1.3-5.x.
- rename or move flex, and python binaries if applicable from 
/usr/local/bin .  if the default paths have not been modified, this 
directory will be searched before /usr/bin.
- install python first – “up2date python” – if up2date fails, one strong 
possibilities is that the python it files does not have the correct 
scripts in the site-packages directory under the pythonx.x directory. 
Next, using this command will also resolve any dependencies needed to make 
python work.  All should be done as root.
- next install mod_python – “up2date python” – this should address 
installing and resolving dependencies.
- check install and version
- “python –V” – see version above
- “which python” – should show “/usr/bin/python”
- check if mod_python.so installed in “/etc/httpd/modules”
- add the required changes into the .conf file - 
            - add the load directive for mod_python.so
            - test if the server will read the .so file correctly
                        - stop the server – “/sbin/service httpd stop”
                        - execute “/usr/sbin/httpd –X –e DEBUG – the list 
of .so files loading should scroll by, mod_python.so should be in this 
- assuming no errors/warnings to this point, restart the web server – 
“/sbin/service httpd restart
- now you will need to add into “python.conf” the <Directory…> directives, 
the restart server.
Hope this helps.
Good luck.

Subject: [mod_python] A newbie question

I attempted to install Apache 2.0.54 (or Apache 2.2), python 2.4 and 
mod_python 3.2.8 on AS 4 from source codes, but I failed. The mod_python 
does not generate mod_python.so. Does anyone  run into the same problem 
and have a solution to fix it? Thanks! JW
