duke@2 | 1 | README: |
ohair@276 | 2 | This file should be located at the top of the OpenJDK Mercurial root |
ohair@276 | 3 | repository. This root repository will include a "make" directory, |
ohair@276 | 4 | and a Makefile for building the entire OpenJDK. |
ohair@276 | 5 | A full OpenJDK repository set (forest) should also include the following |
ohair@276 | 6 | 6 nested repositories: |
ohair@276 | 7 | "jdk", "hotspot", "langtools", "corba", "jaxws" and "jaxp". |
ohair@276 | 8 | There are also several source downloads for the jax* repositories that |
ohair@276 | 9 | will be needed. |
ohair@276 | 10 | |
ohair@276 | 11 | This one root repository can be obtained with something like: |
ohair@276 | 12 | hg clone http://hg.openjdk.java.net/jdk7/jdk7 openjdk7 |
ohair@276 | 13 | To make sure you have all the nested repositories, you can run: |
ohair@276 | 14 | cd openjdk7 && sh ./get_source.sh |
ohair@276 | 15 | (This is identical to using the Mercurial Forest Extension command |
ohair@276 | 16 | 'hg fclone http://hg.openjdk.java.net/jdk7/jdk7 openjdk7'). |
ohair@276 | 17 | People unfamiliar with Mercurial should read the first few chapters of |
ohair@276 | 18 | the Mercurial book: http://hgbook.red-bean.com/read/ |
duke@2 | 19 | |
duke@2 | 20 | See http://openjdk.java.net/ for more information about the OpenJDK. |
duke@2 | 21 | |
duke@2 | 22 | Simple Build Instructions: |
ohair@276 | 23 | |
ohair@276 | 24 | 0. Get the necessary system software/packages installed on your system, see |
ohair@276 | 25 | http://hg.openjdk.java.net/jdk7/build/raw-file/tip/README-builds.html |
duke@2 | 26 | |
ohair@276 | 27 | 1. If you don't have a jdk6 installed, download and install a JDK 6 from |
duke@2 | 28 | http://java.sun.com/javase/downloads/index.jsp |
ohair@276 | 29 | Set the environment variable ALT_BOOTDIR to the location of JDK 6. |
duke@2 | 30 | |
ohair@276 | 31 | 2. Check the sanity of doing a build with your current system: |
duke@2 | 32 | gnumake sanity |
duke@2 | 33 | See README-builds.html if you run into problems. |
duke@2 | 34 | |
ohair@276 | 35 | 3. Do a complete build of the OpenJDK: |
duke@2 | 36 | gnumake all |
duke@2 | 37 | The resulting JDK image should be found in build/*/j2sdk-image |
duke@2 | 38 | |
ohair@262 | 39 | where gnumake is GNU make 3.81 or newer, /usr/bin/make on Linux and |
duke@2 | 40 | /usr/sfw/bin/gmake or /opt/sfw/bin/gmake on Solaris. |
