.
- 32bit build
- Builds done on 32bit machines, or creating 32bit native code object files, libraries, and executables. A 32bit JDK build always includes a complete JDK image.
...
- 6-
...
- open
- Release name for OpenJDK 6.
...
- 64bit build
- Builds done on 64bit capable machine and creating 64bit native code object files, libraries, and executables.
...
- On Linux 64bit and Windows 64bit, a 64bit build is a complete JDK build, and although
...
- a 32bit build could be done on a 64bit Linux or Windows machines, it's not common practice.
...
- On Solaris, a 64bit build is just the native code object files, libraries, and executables,
...
- which means that a Solaris 64bit build needs to be 'added on' to a Solaris 32bit build.
...
- Only on Solaris can you run one JDK and ask for either a 32bit execution (-d32) or a
...
- 64bit execution (-d64).
...
- ARCH_DATA_
...
- MODEL
- Makefile variable setting that determines if it is a 32 or 64 bit build. Set to 32 or 64.
...
- ALT_
...
- setting
- Makefile variable naming convention
...
- used in JDK Makefiles to select alternative paths, locations, or settings.
...
- ALT_BINARY_PLUGS_
...
- PATH
- Location of OpenJDK binary plugs.
...
- ALT_
...
- BOOTDIR
- Location of JDK used to build the JDK, usually the previously released JDK.
...
- ALT_COMPILER_
...
- PATH
- Alternative location for the native compiler to use.
...
- ALT_CORBA_
...
- DIST
- The location of the corba "dist" directory to get the corba files from.
...
- ALT_CUPS_HEADERS_
...
- PATH
- Location of the CUPS include files.
...
- ALT_DEPLOY_
...
- MSSDK
- Location of Platform SDK installation (Windows only).
...
- ALT_DXSDK_
...
- PATH
- Location of DirectX 9 SDK installation (Windows only).
...
- ALT_FREETYPE_HEADERS_
...
- PATH
- Location of the freetype native include files.
...
- ALT_FREETYPE_LIB_
...
- PATH
- Location of the freetype native libraries.
...
- ALT_JAXP_
...
- DIST
- The location of the jaxp "dist" directory to get the jaxp files from.
...
- ALT_JAXWS_
...
- DIST
- The location of the jaxws "dist" directory to get the jaxws files from.
...
- ALT_JDK_IMPORT_
...
- PATH
- The location of the JDK import image.
...
- This is used to fill in the gaps when doing partial builds of the jdk.
...
- This should be a recent build of the same version of the JDK you are building.
...
- ALT_LANGTOOLS_
...
- DIST
- The location of the langtools "dist" directory to get the javac files from.
...
- ALT_PARALLEL_COMPILE_
...
- JOBS
- On Linux and Solaris, the parallel build feature of GNU make is used to build all
...
- the object files for a library in parallel, based on this setting.
...
- Depending on the number of CPUs you have, this number should be set to something
...
- between nCPUS+1 and nCPUS*2.
...
- Each system is different and some experimentation may be required.
...
- ALT_PREVIOUS_JDK_
...
- IMAGE
- When doing a full control build, one of the last steps is to compare the JDK image
...
- you just created with a previous JDK image. This is the image you will compare with.
...
- Often this is the previous JDK release, and could be the same as ALT_BOOTDIR.
...
- ALT_SLASH_
...
- JAVA
- Many of the default paths for the various ALT_* settings are rooted at the path
...
- "/java/" or "J:/" on Windows. This variable allows you to change that root in case
...
- you have created an exact copy of the "/java/" area in a local disk area or faster
...
- access location.
...
- Unfortunately, this layout isn't completely documented and may need to be deduced
...
- from the output of 'gnumake sanity' output.
...
- BOOTDIR
...
- See ALT_BOOTDIR.
...
- BUG
- See Change Request.
...
- BugID
- See Change Request.
...
- CCC
- JDK compatibility process for developers. TBD for OpenJDK.
...
- CR
- See Change Request.
...
- Change Request
- A Change Request or CR (also referred to as a bug, rfe, or bugid) is an entry in the
...
- Sun bug tracking system. These can be seen partially from http://bugs.sun.com.
- Sun bug tracking system. These can be seen partially from http://bugs.sun.com
...
- The OpenJDK bug tracking system is TBD, but for now CR's will have to do.
...
- A CR number is a 7 digit number, and one of these is required for every change made
...
- to the JDK sources.
...
- If you see the 7 character pattern "NoBugID" used, it means that no official CR was
...
- created for this change, you should rarely if ever see them.
...
- Core libraries
- A subset of the JDK is considered to be the
...
- Core Libraries.
- DSCM
- Distributed Source Code Management (SCM) system.
...
- Some examples are TeamWare, Mercurial, and git.
...
- Users can 'clone' or create child repositories or workspaces that are complete
...
- copies allowing for distributed development that can optionally be merged back
...
- into the primary branch of development or not.
...
- CVS and SubVersion are not distributed, there is only one instance of a repository.
...
- GTEE
- An internal Sun testing grid system used to test JDK promotions and releases.
...
- HotSpot
- The JDK VM or JVM.
...
- There are various implementations of the HotSpot VM: client, server, tiered, and kernel.
...
- JAVA_
...
- HOME
- An environment variable used to trigger the 'java' found in your PATH to use a different
...
- JDK image. Unfortunately, not all 'java' startup scripts obey this env variable.
...
- It's also used by many java tool startup scripts to determine what 'java' to run, bypassing
...
- the 'java' found in the PATH setting.
...
- Setting this variable during a JDK build is a bad idea, don't do it.
...
- JDK_IMPORT_
...
- PATH
- See ALT_JDK_IMPORT_PATH.
...
- JPRT
- An internal Sun build system that was created from the hotspot specific PRT build system.
...
- MASTER
- The name given to the primary or master copy of the sources for a release.
...
- It is the MASTER sources that JDK promotion builds are built from.
...
- NoBugID
- See Change Request.
...
- PIT
- A formal testing process that integrators are required to go thorough prior to integrating
...
- their source changes into the MASTER area.
...
- Platform SDK
- Also spelled "PlatformSDK" or just 'PSDK".
...
- This is a Platforms specific SDK kit that must be installed on Windows systems
...
- in order to build the JDK.
...
- With Windows 32bit, the Visual Studio 2003 compiler installation may include at least
...
- a partial PlatformSDK
...
- image, but the full Windows Platform SDK may also need to be installed on 32bit systems.
...
- On Windows 64bit systems, the PlatformSDK is critical because the native compiler for 64bit
...
- will come from this SDK.
...
- The specific version of the PlatformSDK you install is critical, and depends on the
...
- version of the JDK you are building.
...
- PRT
- See JPRT.
...
- PSDK
- See Platform SDK.
...
- RFE
- See Change Request.
...
- SCCS
- Source Code Control System. Unix per-file source code change system.
...
- Used by TeamWare to manage the changes to individual files.
...
- SCCS keyword
- A pattern of a '%' uppercase letter and another '%', e.g. %W%, that when used in a
...
- source file controlled by SCCS would get expanded on a 'sccs get' operation and
...
- not expanded during the edit of a source file.
...
- Lots of different types of keywords were available, e.g.
...
- version numbers of files, dates of changes, etc.
...
- SCCS revision
- The commit of a change to an SCCS file creates an SCCS rev for that file.
...
- SDK
- Software Development Kit. A horribly overused term which means a big bag of stuff
...
- that is usually associated with helping you develop some kind of software that uses
...
- a particular API or platform.

...
- This version was used for the jdk6 release, and what is being used now

...
- binary plugs
- The missing parts of the JDK whose source is not available in the OpenJDK.

...
- bringover
- TeamWare action of pulling changes from one workspace to another.
...
- Conflicts are allowed and would have to be resolved.
...
- build flavor
