New submission from Alan Hourihane: When building python with static extensions and therefore there are no shared extensions to be built the extension list can be NULL, and therefore 0 length.
This results in this error.... running build running build_ext INFO: Can't locate Tcl/Tk libs and/or headers Traceback (most recent call last): File "/var/tmp/portage/dev-lang/python-2.7.5-r2/work/Python-2.7.5/setup.py", line 2017, in <module> main() File "/var/tmp/portage/dev-lang/python-2.7.5-r2/work/Python-2.7.5/setup.py", line 2011, in main 'Lib/smtpd.py'] File "/var/tmp/portage/dev-lang/python-2.7.5-r2/work/Python-2.7.5/Lib/distutils/core.py", line 152, in setup dist.run_commands() File "/var/tmp/portage/dev-lang/python-2.7.5-r2/work/Python-2.7.5/Lib/distutils/dist.py", line 953, in run_commands self.run_command(cmd) File "/var/tmp/portage/dev-lang/python-2.7.5-r2/work/Python-2.7.5/Lib/distutils/dist.py", line 972, in run_command cmd_obj.run() File "/var/tmp/portage/dev-lang/python-2.7.5-r2/work/Python-2.7.5/Lib/distutils/command/build.py", line 127, in run self.run_command(cmd_name) File "/var/tmp/portage/dev-lang/python-2.7.5-r2/work/Python-2.7.5/Lib/distutils/cmd.py", line 326, in run_command self.distribution.run_command(command) File "/var/tmp/portage/dev-lang/python-2.7.5-r2/work/Python-2.7.5/Lib/distutils/dist.py", line 972, in run_command cmd_obj.run() File "/var/tmp/portage/dev-lang/python-2.7.5-r2/work/Python-2.7.5/Lib/distutils/command/build_ext.py", line 339, in run self.build_extensions() File "/var/tmp/portage/dev-lang/python-2.7.5-r2/work/Python-2.7.5/setup.py", line 266, in build_extensions longest = max([len(e.name) for e in self.extensions]) ValueError: max() arg is an empty sequence To fix I replaced this line in setup.py longest = max([len(e.name) for e in self.extensions]) to this... longest = 0 for e in self.extensions: longest = max(longest, len(e.name)) ---------- components: Build messages: 200922 nosy: alanh priority: normal severity: normal status: open title: Build fails when there are no shared extensions to be built type: compile error versions: Python 2.7 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue19346> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
