问题:编译之前,用了make clean清除了之前编译的文件,再用make编译的时候就是报出这样的错误,一直不明白是什么原因??
解决:然后用make distclean了一下,在进行编译,结果没有发生上面的错误了,e......,看来make distclean清除得比较彻底
分析:原来之前在自己目录下面创建了一个Denny用户,之前的uboot也是在Denny这个用户名下进行编译的,但是后来,删除这个Denny用户后,把原来的uboot拷贝到新建的qinyuanyi用户的目录下面,在对uboot进行编译时,只用make clean清除,清除不够彻底,看来还是用make distclean清除比较彻底
下面对make clean 和 make distclean知识补充:
make clean:仅仅是清除之前编译的可执行文件及配置文件。
make distclean:要清除所有生成的文件。
