Kelly O'Hair | 213481a | 2010-12-22 12:25:52 -0800 | [diff] [blame] | 2 | This file should be located at the top of the OpenJDK Mercurial root |
| 3 | repository. This root repository will include a "make" directory, |
| 4 | and a Makefile for building the entire OpenJDK. |
| 5 | A full OpenJDK repository set (forest) should also include the following |
| 6 | 6 nested repositories: |
| 7 | "jdk", "hotspot", "langtools", "corba", "jaxws" and "jaxp". |
| 8 | There are also several source downloads for the jax* repositories that |
| 9 | will be needed. |
| 10 | |
| 11 | This one root repository can be obtained with something like: |
| 12 | hg clone http://hg.openjdk.java.net/jdk7/jdk7 openjdk7 |
| 13 | To make sure you have all the nested repositories, you can run: |
| 14 | cd openjdk7 && sh ./get_source.sh |
| 15 | (This is identical to using the Mercurial Forest Extension command |
| 16 | 'hg fclone http://hg.openjdk.java.net/jdk7/jdk7 openjdk7'). |
| 17 | People unfamiliar with Mercurial should read the first few chapters of |
| 18 | the Mercurial book: http://hgbook.red-bean.com/read/ |

Kelly O'Hair | 213481a | 2010-12-22 12:25:52 -0800 | [diff] [blame] | 35 | 3. Do a complete build of the OpenJDK: |
Kelly O'Hair | f240c00 | 2011-03-22 08:15:39 -0700 | [diff] [blame] | 36 | make all |
J. Duke | 686d76f | 2007-12-01 00:00:00 +0000 | [diff] [blame] | 37 | The resulting JDK image should be found in build/*/j2sdk-image |
| 38 | |
Kelly O'Hair | f240c00 | 2011-03-22 08:15:39 -0700 | [diff] [blame] | 39 | where make is GNU make 3.81 or newer, /usr/bin/make on Linux usually |
| 40 | is 3.81 or newer. |
