You will also need Ant 1.7.1 or better, as well as g++ 4.4 or better (optionally xlC 11.1 or better), binutils, wget, and GNU make.
Note for Linux users: The X10 build uses the javah task, which is not included in the default ant package. You would need to install ant-nodeps (on RedHat/Gentoo-based systems) or ant-optional (on Debian/SuSE-based systems).
Note for MacOS users: The default Java installation on recent versions of MacOS is not a complete JDK even if it comes with the javac compiler. You must install a proper JDK to build X10 from sources, that is, either a Java Developer Package for Java 6 from Apple or a Java 7 JDK from Oracle. If JAVA_HOME is not set, the build will use the preferred Java installation as returned by /usr/libexec/java_home.
-Note for Windows users: You must build X10 within the cygwin environment. The minimum Cygwin version required to build X10 is 1.7.1, as Cygwin releases prior to 1.7.1 broke the shared library behavior of g++ 4.3.2. Make sure you have these packages: gcc, g++, wget, make, binutils, diffutils, libtool, git, patch, time.
