rt所示，
我是Macos系统，想写个串口通信的软件，知道有java的comm，但是macos下只能使用和comm差不多的RXTX，用import gnu.io.*
从网上下载了RXTXcomm.jar、librxtxSerial.jnilib、librxtxParallel.so、librxtxSerial.so四个文件，
但是在我想要把这些文件放到jdk目录下对应的位置的时候：
按之前前辈们的做法是（他们是在linux下成功的）：
“如果要脱离eclipse单独执行串口通信程序，将librxtxSerial.so复制到$JAVA_HOME/jre/lib/amd64/目录下（如果是32位系统应该是i386或者i686，而不是amd64）就OK了。”
这里的amd64指代$(ARCH)，差不多是体系结构的东西，但是我在我的jdk下没有找类似的目录……
我用ls -l命令就发现了以下的文件：（根本连目录都没几个）
于是这一步就告吹了，求助有没有大神知道该怎么办…我看其他的两个帖子也都是需要到$（ARCH）里面的。而官网上是Make的方法，也是和这个相关的似乎…总之就是绕不过这个了

不知道该怎么解决。
由于我java用的不多……电脑为了节约空间，也没装java开发用的IDE，.java文件甚至是用Android Studio来写的。所以有点懵逼……
