1、准备测试源代码和Makefile
helloworld.c
#include <stdio.h>
int main(void)
{
printf("hello world!/n");
return 0;
}
Makefile
CFLAGS = -Wall -O2
CC = arm-linux-gcc
INSTALL = install
TARGET = HelloWorld
all: $(TARGET)
HelloWorld: helloworld.c
$(CC) $(CFLAGS) $< -o $@
install: $(TARGET)
$(INSTALL) $^ $(DESTDIR)/usr/bin
clean distclean:
rm -rf *.o $(TARGET)
# ----------------------------------------------------------------------------
.PHONY: $(PHONY) install clean distclean
2、编译运行
执行make命令，生成hello.o。在开发板通过nfs协议mount命令挂载主机共享目录，进入目录执行./hello，结果显示“hello world！”，应用程序测试结束。
