--- Comment #3 from __vic <d.v.a at ngs dot ru> 2012-06-15 08:34:13 UTC --- When I'm trying link libstdc++.a statically to my .so I see messages like: "undefined versioned symbol name std::defer_lock@@GLIBCPP_3...." $ nm libstdc++.a | grep @ shows me that archive contains versioned symbols. Do you need the entire list?
