64-bit machines (dual dual-core AMD Opteron) First: Configuring Zope installation Using Python interpreter at /usr/local/bin/python2.4 /usr/local/bin/python2.4 install.py -q build Dependencies/ExtensionClass-Zope-2.9.2/ExtensionClass/_ExtensionClass.c: In function `PyExtensionClass_Export_': Dependencies/ExtensionClass-Zope-2.9.2/ExtensionClass/_ExtensionClass.c:768: warning: cast from pointer to integer of different size /usr/local/bin/python2.4 install.py -q build /usr/local/bin/python2.4 install.py -q install --skip-build --home "/usr/local/src/zope/Zope2.9" _ExtensionClass is not 64-bit clean. I believe the warning can be ignored. When I install Zope 2.9.0 on a 64 bit machine the path to the system is .../Zope/lib64/python/... but with Zope 2.9.2, also on a 64-but machine the path to the system is ...Zope/lib/python/.... Why the change? --
