Hello, I went to http://cvs.zope.org/Zope/ and downloaded a tarball via the link at bottom of page, and proceeded to attempt a build (python setup.py install) on a Windows XP Home system having Python 2.2.2 and VC98. When it got to the build_ext stage, it failed with the following traceback. self.build_temp is None at that point. I tried setting --build-base, but it didn't help. Thanks for any help or suggestions. running build_ext Traceback (most recent call last): File "C:\Temp\Zope\setup.py", line 1033, in ? distclass=ZopeDistribution, File "C:\Python22\lib\distutils\core.py", line 138, in setup dist.run_commands() File "C:\Python22\lib\distutils\dist.py", line 893, in run_commands self.run_command(cmd) File "C:\Python22\lib\distutils\dist.py", line 913, in run_command cmd_obj.run() File "C:\Temp\Zope\setup.py", line 148, in run install.run(self) File "C:\Python22\lib\distutils\command\install.py", line 491, in run self.run_command('build') File "C:\Python22\lib\distutils\cmd.py", line 330, in run_command self.distribution.run_command(command) File "C:\Python22\lib\distutils\dist.py", line 913, in run_command cmd_obj.run() File "C:\Python22\lib\distutils\command\build.py", line 107, in run self.run_command(cmd_name) File "C:\Python22\lib\distutils\cmd.py", line 330, in run_command self.distribution.run_command(command) File "C:\Python22\lib\distutils\dist.py", line 912, in run_command cmd_obj.ensure_finalized() File "C:\Python22\lib\distutils\cmd.py", line 112, in ensure_finalized self.finalize_options() File "C:\Python22\lib\distutils\command\build_ext.py", line 168, in finalize_options self.build_temp = os.path.join(self.build_temp, "Release") File "C:\Python22\lib\ntpath.py", line 72, in join assert len(path) > 0 TypeError: len() of unsized object -- Mike
