In case if here is a fast cpu and make is done in parallel we may have the following error | GEN arch/x86/sys-exec-tbl.c | GEN arch/x86/syscalls.S | CC arch/x86/crtools.o | CC arch/x86/cpu.o | CC arch/x86/syscalls.o | LINK arch/x86/syscalls.built-in.o | In file included from include/restorer.h:12:0, | from arch/x86/crtools.c:19: | include/lock.h: In function ‘futex_set_and_wake’: | include/lock.h:56:2: error: implicit declaration of function ‘sys_futex’ [-Werror=implicit-function-declaration] | cc1: all warnings being treated as errors | make[1]: *** [arch/x86/crtools.o] Error 1 | make: *** [arch/x86] Error 2 This is because crtools.c includes syscall.h but this header is generated by a special script. So use $(deps-after) feature provided by our make engine making sure the header is generated before the deps are started to build.
