The below mail is about a very similar problem but with an older Gcc, and since these symbols are provided by gcc, this makes a difference. Try removing from arch/um/kernel/gmon_syms.c these 2 lines: extern void __bb_init_func(void *); EXPORT_SYMBOL(__bb_init_func); and recompiling. Better yet, try if adding the weak attribute like below fixes the problem: extern void __bb_init_func(void *) __attribute__((weak)); EXPORT_SYMBOL(__bb_init_func); Another possible thing to check is what happens with CONFIG_STATIC_LINK=y (edit it by hand and do not enable GPROF for now, that is yet another thing). > Done: make clean && make distclean && make allmodconfig ARCH=um > # CONFIG_GPROF is not set > CONFIG_GCOV=y This results from allmodconfig? Mmpf, that is not so nice (allmodconfig should not result in a debug kernel). Even if allmodconfig is not a _smart_ setting (set to y or m everything). > # > # UML-specific options > # > # CONFIG_MODE_TT is not set > # CONFIG_STATIC_LINK is not set > CONFIG_MODE_SKAS=y > Build: make linux ARCH=um > > > edit file: uml/arch/um/os-Linux/sys-i386/registers.c > Ending: > > arch/um/kernel/built-in.o:(__ksymtab+0x238): undefined reference to > `__bb_init_func' > arch/um/os-Linux/built-in.o: In function `do_syscall_stub': > arch/um/os-Linux/skas/mem.c:63: undefined reference to > `get_safe_registers' > arch/um/os-Linux/built-in.o: In function `copy_context_skas0': > arch/um/os-Linux/skas/process.c:333: undefined reference to > `get_safe_registers' Since it arrives to this point, get_safe_register should be undefined only because of the previous failure. > I see it must be solved.
