Setting Up an Environment for the NetBeans Make-Based OpenJDK Projects

Take the following steps to set up Linux Ubuntu 7.0 "Feisty Fawn" in preparation for your work with the make-based NetBeans OpenJDK projects. For all other operating systems, see the "README-builds.html" document, which is found in the top-level directory of your downloaded openjdk sources.

When encountering problems of any kind, please consult the Troubleshooting Guide.

Use the Synaptic Package Manager

Install the following packages, via the Synaptic Package Manager:

• build-essential
• gawk
• libasound2-dev
• libcupsys2-dev
• libmotif-dev
• libxp-dev
• x11proto-print-dev
• xlibs-dev

Set Environment Variables

In your home directory, create a folder called .openjdk. If you do not create it, the IDE creates it for you the first time you build a project. Within this folder, create a file called build.properties. In the build.properties file, define the following:

• bootstrap.jdk The location of the JDK 7. When building the OpenJDK, you will need what is called an "import JDK7 installation". This should be the same basic version as the OpenJDK source you are building.
• make.options
  • ALT_BOOTDIR. The location of the bootstrap JDK installation, which is a JDK 6 installation. For build performance reasons, it is very important that this bootstrap JDK be made available on the local disk of the machine doing the build.
  • ALT_CLOSED_JDK_IMPORT_PATH. The location of the import JDK 7 installation.

For example:

bootstrap.jdk=/usr/jdk1.7.0

make.options=\
            ALT_BOOTDIR=/home/jdk1.6.0_01 \
            ALT_CLOSED_JDK_IMPORT_PATH=/use/jdk1.7.0
