Hello: Are there any comments regarding the missing of a module named FCNTL.py ? It happens that I just built Zope 2.3 from source on a Python 1.5.2 installation and after compiling and building successfully just after the "./start" command, Zope crases with a "no module named FCNTL" . Lookign around found that this FCNTL.py has to be manually created (at least on some Python installations) with the Python utility h2py which, in my machine is at ~[PythonBaseDir]/Python-1.5.2/Tools/scripts/h2py.py and giving the path of fcntl.h as its argument so: [PythonDir]/Python-1.5.2/Tools/scripts/h2py.py /usr/include/fcntl.h I did this standing at the /usr/local/Zope directory where I just untarred Zope. The h2py script created the FCNTL.py right on the Zope home directory, now it runs correctly. My question is ¿has anyone seen this before? , It never happened to me on Zope versions earlier than 2.3 and 2.3 betas ) Seems like there is something missing either on the Python RPM install or on the Zope install..... Comments Suggestions ? Just by the way, recommended trustworthy ways to find out if the Python installation has been compiled with threads enabled -besides knowing that it is a plain vanilla RPM install and what that may or may not imply - ...?
