This results in many system headers that reference the C standard headers being unusable because the C standard headers are not found (eg. sys/resource.ph -> bits/resource.ph -> linux/types.ph -> stddef.ph -> stddef.ph not found, bug 170088 ). The perl build process should find the C standard headers in their correct location, as many system perl headers that are shipped by perl reference them. Version-Release number of selected component (if applicable): ALL How reproducible: 100% Steps to Reproduce: $ perl -e 'require "sys/resource.ph";' Actual results: Fails due to missing stddef.ph Expected results: No error Additional info: -- Configure bugmail: https://bugzilla.redhat.com/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
