            Bug ID: 22445
           Summary: libc++ does not build when using libstdc++/libsupc++
                    from GCC 5.0 as the ABI library
           Product: libc++
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: All Bugs
          Assignee: unassignedclangbugs at nondot.org
          Reporter: eric at efcs.ca

    Classification: Unclassified

Between 4.9.2 and the current GCC TOT a definition was moved into "cxxabi.h"
that depends on internals of libstdc++'s <typeinfo>. Since libc++'s <typeinfo>
does not provide the needed internals we fail to build when including cxxabi.h.

This is a GCC bug that tracked the moving of the definition:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=61728

I'll contact jason merril to see what can be done on their end.
