binutils 2.22 changed ld default from --copy-dt-needed-entries to -no-copy-dt-needed-entries. This revealed that some objects are linked implicitly with libtinfo and newer ld fails to build relevant executables. Below is short explanation why we should not do that... http://fedoraproject.org/wiki/UnderstandingDSOLinkChange says: The default behaviour for ld (my note: before version 2.22) allows users to 'indirectly' link to required objects/libraries through intermediate objects/libraries. While this is convenient, it can also be dangerous because it makes your program's dependencies tied to the dependencies of other objects. If those objects ever change their linkages, they can break your program without any changes to your own code!
