Hello We have worked on a fix for bdist_rpm, to avoid the error that occurs under Fedora or RedHat when the optimize flag is not activated. http://bugs.python.org/issue1533164 I am about to introduce a new option for this command, called "force-optimize" (and activated by default) This new option makes the bdist_rpm command drive the install command with the "optimize" flag activated by default (this fixes the problem) The rationale to introduce a new option is to make sure people don't get confused between the optimize flag that is forced when building a rpm package, and the "regular" optimize option used by the install command. This will prevent undesired side-effects. For instance, writing a setup.cfg with "optimize" to build rpms, might interfer when someone tries to tries to install the same package under Jython, Any opinion ? Otherwise I'll commit it this way Regards Tarek -- Tarek Ziadé | Association AfPy | www.afpy.org Blog FR | http://programmation-python.org Blog EN | http://tarekziade.wordpress.com/
