lo lo,
I'm trying to compile 2.6.32.60 with gcc 4.7.2, and getting the
following error:
CC arch/x86/kernel/ptrace.o

make[2]: *** [arch/x86/kernel/ptrace.o] Error 1
make[1]: *** [arch/x86/kernel] Error 2
make: *** [arch/x86] Error 2
My environment looks like:
Linux 3.2.30, glibc 2.16, gcc 4.7.2
If I comment out the ancient line, kernel compiles fine.
Willy says:
| The affected entry is only used there :
| arch/x86/include/asm/ptrace.h:extern void syscall_trace_leave(struct pt_regs
*);
| arch/x86/include/asm/thread_info.h:/* work to do in syscall_trace_leave() */
| arch/x86/kernel/entry_32.S: ENABLE_INTERRUPTS(CLBR_ANY) # could let
syscall_trace_leave() call
| arch/x86/kernel/entry_32.S: call syscall_trace_leave
| arch/x86/kernel/entry_64.S: call syscall_trace_leave
| arch/x86/kernel/ptrace.c:asmregparm void syscall_trace_leave(struct pt_regs
*regs)
| So if the two calls above don't need the include then maybe we can
| safely remove it.
