4.1.uClinux-dist/user/hello/Makefile

EXEC = hello OBJS = hello.o all: $(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. 将用户程序编译进romfs

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