Makefile中 ruvs 是什么意思?
看到Makefile中有下面一行:
$(AR) ruvs $(MODELLIB) $(OBJS)
请教 ruvs 什么意思?
makefile
------解决方案--------------------那是ar命令的参数,man ar
------解决方案--------------------那是4个选项的组合
执行ar --help
可以看到每个选项的含义
r[ab][f][u] - replace existing or insert new file(s) into the archive
[u] - only replace files that are newer than current archive contents
[s] - create an archive index (cf. ranlib)
[v] - be verbose
