I installed the Zope binary on a linux box, and everything went well. User authentication worked successfully with Apache using the 'REMOTE USER' environment variable. Then I tried to get ZMySQLDA to work, but I couldn't get the Zope Python install to find 'libmysqlclient'. I got a build of Python 1.5.1 to successfully import MySQL. So I decided to reinstall Zope from source, so that I could use my own Python. The source Zope built okay, but when I tried to start Zope through the web browser I got an "Internal Server Error" message from Apache, the error log said I had a "Premature end of script header". I've checked permission on the var dir and user authentication still seems to work fine. I couldn't figure out why I was getting the error, so I tried re-installing the binary distribution of Zope. No luck there either, I get the same "premature end of script header" error message. I've checked the Zope.cgi file, and it seems o.k. Does anyone have any idea why Zope.cgi is failing on me? Is there something I have to do to Apache or Zope if I've removed the Zope folder and then untarred and re-installed a new Zope? Don't know if this'll help, but this is what I get when I run Zope.cgi from the command line: Status: 500 Internal Server Error Bobo-Exception-File: lib/python/ZPublisher/Request.py Content-Type: text/html Bobo-Exception-Type: exceptions.KeyError Bobo-Exception-Value: SCRIPT_NAME Content-Length: 363 Bobo-Exception-Line: 167 <html> <head> <title>exceptions.KeyError</title> </head> <body> Sorry, an error occurred.<p> <!-- Traceback (innermost last): File lib/python/ZPublisher/Publish.py, line 870, in publish_module File lib/python/ZPublisher/Publish.py, line 248, in __init__ File lib/python/ZPublisher/Request.py, line 167, in __init__ KeyError: SCRIPT_NAME --> </body> Kevin Teague Kevin@StudioInfo.com Temporary Nelson address: #6-560 Baker street Phone: 250-354-1845 * Dedicated Fax: 250-354-1890
