In C, we can forward declare static structure instances. That doesn't work in C++ though. C++ treats these as definitions. So then the compiler complains about symbol redefinition, like: src/gdb/elfread.c:1569:29: error: redefinition of ‘const sym_fns elf_sym_fns_lazy_psyms’ src/gdb/elfread.c:53:29: error: ‘const sym_fns elf_sym_fns_lazy_psyms’ previously declared here The intent of static here is naturally to avoid making these objects visible outside the compilation unit. The equivalent in C++ would be to instead define the objects in the anonymous namespace. But given that it's desirable to leave the codebase compiling as both C and C++ for a while, this just makes the objects extern. (base_breakpoint_ops is already declared in breakpoint.h, so we can just remove the forward declare from breakpoint.c) gdb/ChangeLog: 2015-02-11 Tom Tromey <tromey@redhat.com> Pedro Alves <palves@redhat.com> * breakpoint.c (base_breakpoint_ops): Delete. * dwarf2loc.c (dwarf_expr_ctx_funcs): Make extern. * elfread.c (elf_sym_fns_gdb_index, elf_sym_fns_lazy_psyms): Make extern. * guile/guile.c (guile_extension_script_ops, guile_extension_ops): Make extern. * ppcnbsd-tdep.c (ppcnbsd2_sigtramp): Make extern. * python/py-arch.c (arch_object_type): Make extern. * python/py-block.c (block_syms_iterator_object_type): Make extern. * python/py-bpevent.c (breakpoint_event_object_type): Make extern. * python/py-cmd.c (cmdpy_object_type): Make extern. * python/py-continueevent.c (continue_event_object_type) * python/py-event.h (GDBPY_NEW_EVENT_TYPE): Remove 'qual' parameter.
