试验一下

 先试一下，简单的程序，效果

#incude<stdio.h>

int main(void){

printf("this is a simple programme for test!\n");

return 0;

}

 

LDFLAGS_bootp   :=-p --no-undefined -X \
   9                 --defsym initrd_phys=$(INITRD_PHYS) \
  10                 --defsym params_phys=$(PARAMS_PHYS) -T
  11AFLAGS_initrd.o :=-DINITRD=\"$(INITRD)\"

15# Note that bootp.lds picks up kernel.o and initrd.o
16$(obj)/bootp:   $(src)/bootp.lds $(addprefix $(obj)/,init.o kernel.o initrd.o) FORCE
17        $(call if_changed,ld)
18        @:
19
20# kernel.o and initrd.o includes a binary image using

#incude<stdio.h>

int main(void){

printf("this is a simple programme for test!\n");

return 0;

}
