Trouble compiling Zope 2.4.1 on Mac OS 10.1: installed a fresh 10.1 that I just got from Apple downloaded the Zope 2.4.1 src tried 'python wo_pcgi' with both a Python 2.2a4 I just made and with my previous Python 2.1, both with and without sudo Whatever I do, it breaks in the same place. Here's the end of the output: sed -f sedscript ./Makefile.pre.in >Makefile.pre /usr/local/lib/python2.1/config/makesetup \ -m Makefile.pre -c /usr/local/lib/python2.1/config/config.c.in Setup -n /usr/local/lib/py\ thon2.1/config/Setup.config /usr/local/lib/python2.1/config/Setup.local /usr/local/lib/python2.1/co\ nfig/Setup make -f Makefile do-it-again /usr/local/lib/python2.1/config/makesetup \ -m Makefile.pre -c /usr/local/lib/python2.1/config/config.c.in Setup -n /usr/local/lib/py\ thon2.1/config/Setup.config /usr/local/lib/python2.1/config/Setup.local /usr/local/lib/python2.1/co\ nfig/Setup make cc -g -O2 -Wall -Wstrict-prototypes -I/usr/local/include/python2.1 -I/usr/local/include/python2.1 \ -DHAVE_CONFIG_H -I../Components/ExtensionClass/src -c ././../Components/ExtensionClass/src/Extensi\ onClass.c -o ./ExtensionClass.o In file included from /usr/local/include/python2.1/pyport.h:84, from /usr/local/include/python2.1/Python.h:54, from ././../Components/ExtensionClass/src/ExtensionClass.h:114, from ././../Components/ExtensionClass/src/ExtensionClass.c:61: /usr/include/math.h:191: warning: function declaration isn't a prototype cc -bundle -undefined suppress ./ExtensionClass.o -o ./ExtensionClass.so /usr/bin/ld: -undefined error must be used when -twolevel_namespace is in effect make: *** [ExtensionClass.so] Error 1 Traceback (most recent call last): File "wo_pcgi.py", line 117, in ?
