make clean与make distclean的区别

因为执行sbt clean dist百度了下，搜到make也有如下相似命令：

make clean仅仅是清除之前编译的可执行文件及配置文件。 
而make distclean要清除所有生成的文件。

Makefile

在符合GNU Makefiel惯例的Makefile中，包含了一些基本的预先定义的操作：

make

根据Makefile编译源代码，连接，生成目标文件，可执行文件。

make clean

清除上次的make命令所产生的object文件（后缀为“.o”的文件）及可执行文件。

make install

将编译成功的可执行文件安装到系统目录中，一般为/usr/local/bin目录。

make dist

产生发布软件包文件（即distribution package）。这个命令将会将可执行文件及相关文件打包成一个tar.gz压缩的文件用来作为发布软件的软件包。

它会在当前目录下生成一个名字类似“PACKAGE-VERSION.tar.gz”的文件。PACKAGE和VERSION，是我们在configure.in中定义的AM_INIT_AUTOMAKE(PACKAGE, VERSION)。

make distcheck

生成发布软件包并对其进行测试检查，以确定发布包的正确性。这个操作将自动把压缩包文件解开，然后执行configure命令，并且执行make，来确认编译不出现错误，最后提示你软件包已经准备好，可以发布了。

make distclean类似make clean，但同时也将configure生成的文件全部删除掉，包括Makefile。

ps:sbt、maven也有类似的命令

如sbt有命令sbt clean dist

下面是命令输出：
