| Kelly O'Hair | 1c49ac1 | 2010-12-23 18:50:21 -0800 | [diff] [blame] | 18 | 3. Check the sanity of doing a build with the current machine: |
| J. Duke | 319a3b9 | 2007-12-01 00:00:00 +0000 | [diff] [blame] | 19 | cd make && gnumake sanity |
| 20 | See README-builds.html if you run into problems. |

| Kelly O'Hair | 1c49ac1 | 2010-12-23 18:50:21 -0800 | [diff] [blame] | 22 | 4. Do a partial build of the jdk: |
| J. Duke | 319a3b9 | 2007-12-01 00:00:00 +0000 | [diff] [blame] | 23 | cd make && gnumake all |
| 24 | |
| Kelly O'Hair | 1c49ac1 | 2010-12-23 18:50:21 -0800 | [diff] [blame] | 25 | 5. Construct the images: |
| J. Duke | 319a3b9 | 2007-12-01 00:00:00 +0000 | [diff] [blame] | 26 | cd make && gnumake images |
| 27 | The resulting JDK image should be found in build/*/j2sdk-image |
