最近在看周志明大大的《深入理解Java虚拟机》第二版，尝试着在Mac OS X (10.8.4)中build了一遍OpenJDK，make sanity通过了，但是编译JDK中的Mac本地代码却报错了，烦请各位帮忙给看看，多谢了！

楼主用的源码包是OpenJDK 7u6的zip包么？从这里下载的这个：http://www.java.net/download/openjdk/jdk7u6/promoted/b24/openjdk-7u6-fcs-src-b24-28_aug_2012.zip？

如果是的话，楼主能不能先试试改用Mercurial从http://hg.openjdk.java.net/jdk7u/jdk7u下载新的源码下来build试试？有很多Mac OS X上的build问题都在新版解决了的。您遇到的问题看起来很眼熟…例如可能是这个：http://mail.openjdk.java.net/pipermail/macosx-port-dev/2013-February/005359.html

多谢R大，这几天有点小忙，没顾上看这帖子，我照你说的试试看。
