MaxOSX 1.4.2 python 2.4.1 apache 2.0.54 The loader seems to not like the "-undefined suppress" arguments in the final load. I modified dist/setup.py by removing the two "-undefined suppress" and ran configure and make again and the new mod_python does build and seems to work ok. The bit of code which includes "-undefined suppress" came from the patch Graham submitted for MODPYTHON-65.  See http://issues.apache.org/jira/browse/MODPYTHON-65 for details. Not being a Mac person I can't comment further. Feel free to talk among yourselves. ;) Yep, my fault. It will not build on Mac OS X 10.3.9 without that option if you are using the standard version of GCC shipped with the operating system. I'll get onto my new Tiger laptop and try it there (haven't yet), but can you tell me which GCC you are using? I know the GCC version shipped on the box with Tiger, but are you using that, or are you using one supplied with Fink? Was worried that the change might not apply to the Fink version of GCC. The missing bit of information here is that Python on Tiger (10.4) is correctly putting in the config/Makefile used by distutils the required options. Ie.,   LDSHARED=       $(CC) $(LDFLAGS) -bundle -undefined dynamic_lookup   BLDSHARED=      $(CC) $(LDFLAGS) -bundle -undefined dynamic_lookup The duplicated definition of the -undefined option causes grief when setup.py adds it as well. Thus, setup.py will thus need to check first whether the -undefined option already exists. Thus, setup.py should use: if sys.platform == "darwin":         if not '-bundle' in sysconfig.get_config_var("LDSHARED").split():             sysconfig._config_vars["LDSHARED"] = \                     string.replace(sysconfig.get_config_var("LDSHARED"), \                     " -bundle "," -bundle -flat_namespace -undefined suppress ")             sysconfig._config_vars["BLDSHARED"] = \                     string.replace(sysconfig.get_config_var("BLDSHARED"), \                     " -bundle "," -bundle -flat_namespace -undefined suppress ") In Tiger it actually uses '-undefined dynamic_lookup' instead of what I had used which is '-undefined suppress'. If though you try and use '-undefined dynamic_lookup' on Panther (10.3) or earlier you will run up against a further problem in that '-undefined dynamic_lookup' conflicts with the default compilation mode of being compatible with Mac OS X 10.1. Thus, still probably best to use '-undefined suppress', but the check means that it will only be used on older versions of Mac OS X anyway, or at least where the Python config isn't correct. I'll attach a patch to the JIRA report on the original problem shortly. Graham
