uClinux中添加用户应用程式的周详方法

1. uClinux-dist/user/Makefile

dir_$(CONFIG_USER_HELLO_WORLD)

= hello

2. uClinux-dist/config/Configure.help

CONFIG_USER_HELLO_WORLD

A simple hello world program

3. uClinux-dist/config/config.in

找到下面两行

mainmenu_option next_comment

comment 'Miscellaneous Applications'

添加如下一行

bool 'hello'

CONFIG_USER_HELLO_WORLD

4.1.uClinux-dist/user/hello/Makefile

EXEC = helloOBJS = hello.oall: $(EXEC)$(EXEC): $(OBJS)$(CC) $(LDFLAGS) -o $@ $(OBJS) $(LDLIBS)romfs:$(ROMFSINST)    /bin/$(EXEC)clean:-rm -f $(EXEC) *.elf *.gdb *.o

4.2.uClinux-dist/user/hello/hello.c

#include <stdio.h>int main(){printf("Hello, World\n");return 0;}

5. 将用户程式编译进romfs

# cd ~/uClinux-dist# make menuconfig# make dep# make romfs
