Dear all, I have installed SUSE 9.1 then have upgraded to Python-2.3.4 . I have compiled it. Then I have compiled Zope-2.7.3-0. As result it has appeared the following message peter@linux:~/Documents/zope/Zope-2.7.3-0> ./configure --prefix=/opt/zope Configuring Zope installation Testing for an acceptable Python interpreter... Python version 2.3.4 found at /usr/local/bin/python The optimum Python version (2.3.4) was found at /usr/local/bin/python. The Python interpreter you are using does not appear to have the 'zlib' library module installed. For Zope to be able to run, you must install a Python interpreter which includes the zlib module, or install the zlib library into your Python interpreter manually. The file which represents the library is named 'zlib.so' (UNIX) or 'zlib.dll' (Windows) and is typically located in the 'lib-dynload' directory of your Python's library directory. Some Python packagers ship the zlib module as a separate installable binary. If you are using a system-provided Python installation, you may want to look for a 'python-zlib' package (or something like it) and install it to make the Python zlib module available to Zope. Run the configure script with the --ignore-zlib option to prevent this warning with the understanding that Zope will not start properly until you've installed the zlib module. Well, I have compiled zlib-1.2.1 ./configure -s; make test make install *** zlib test OK *** As I have recompiled Zope-2.7.3-0 I have received again the message you see above. I checked the /usr/lib/python/lib-dynload directory. The zlib.so is there. What have I made wrong? Any help would be greatly appreciated. Thanks.
