1、GDB&makefile
scripts->Makefile编译FLAGS -g
HOSTCC = gcc
HOSTCXX = g++
HOSTCFLAGS :=
HOSTCXXFLAGS :=
include $(srctree)/scripts/Kbuild.include HOSTCFLAGS += $(call hostcc-option,-Wall -Wstrict-prototypes -O2 -g -fomit-frame-pointer,)
HOSTCXXFLAGS += -O2
静态模式：
所有xxxconfig的目标都执行
%config: scripts_basic outputmakefile FORCE customer
customer:
../code/tools/gen_radisson_customer.pl -C ../CUS_FILE config: scripts_basic outputmakefile FORCE customer
# $(Q)mkdir -p include
$(Q)$(MAKE) $(build)=scripts/kconfig $@
$(Q)$(MAKE) -C $(srctree) KBUILD_SRC= .kernelrelease %config: scripts_basic outputmakefile FORCE customer
# $(Q)mkdir -p include
$(Q)$(MAKE) $(build)=scripts/kconfig $@
$(Q)$(MAKE) -C $(srctree) KBUILD_SRC= .kernelrelease

源代码
整个UI的节点保存在“rootmenu”为“head”节点的链表中，即“rootmenu”为跟节点，“rootmenu”没有兄弟节点及父节点。
struct menu {
struct menu *next; //兄弟节点
struct menu *parent; //父节点
struct menu *list; //子节点链表，即下一级菜单的链表
struct symbol *sym; //节点符号
struct property *prompt; //节点提示符
struct expr *dep; //依赖
unsigned int flags;
//char *help;
struct file *file;
int lineno;
void *data;
};如下图的UI：
