  - HCL VersionVault build concepts
    HCL VersionVault supports makefile based building of software systems and provides a software build environment closely resembling that of the make program.
  - Derived objects and configuration records
    Learn about derived objects and configuration records.
  - Pointers on using HCL VersionVault build tools
    Learn how to use VersionVault build tools.
    - Running clearmake
      You can run clearmake from the command line or from the VersionVault File Browser (xclearcase).
    - A simple clearmake build scenario
      clearmake is designed to let developers in makefile-based build environments continue working in their accustomed manner.
    - Accommodating build avoidance
      Learn about clearmake build avoidance.
    - Declaring source dependencies in makefiles
      To implement build avoidance based on time stamps, standard make variants require you to declare all the source file dependencies of each build target.
    - Build-order dependencies
      In addition to source dependencies, makefiles also contain build-order dependencies.
    - Problems with forced builds
      Understand the problems with forced builds.
    - How clearmake interprets double-colon rules
      Double-colon rules are a special kind of makefile construct that allows several independent rules for one target, each with a possibly different build script.
    - Continuing to work during a build
      As your build progresses, other developers continue to work on their files and might check in new versions of elements that your build uses.
    - Using config spec time rules
      If you use a UCM view, your config spec is generated by HCL VersionVault. Do not add time rules to your config spec.
    - Build sessions, subsessions, and hierarchical builds
      Learn about HCL VersionVault build auditing.
      - Subsessions
        A build session can have any number of subsessions, all of which inherit the reference time of the build session.
      - Versions created during a build session
        Any version created during a build session and selected by a LATEST config spec rule is not visible in that build session.
      - Coordinating reference times of several builds
        Different build sessions have different reference times. The best way to assign a series of builds the same reference time is to structure them as a single, hierarchical build.
      - Objects written at more than one level
        Problems occur when the same file is written at two or more session levels (for example, a top-level build session and a subsession): the build audit for the higher-level session does not contain complete information about the file system operations that affected the file.
    - Build auditing and background processes
      If some conditions are met, HCL VersionVault build programs audit background processes correctly.
    - Working with incremental update tools
      The design of the build auditing capability makes it ideal for use with tools that build derived objects from scratch.
    - Adding a version string or time stamp to an executable
      You can incorporate a version string and/or time stamp into a C-language compiled executable using simple techniques.
  - Working with DOs and configuration records
    You can perform operations on derived objects and configuration records.
  - clearmake makefiles and BOS files
    The HCL VersionVault build program, clearmake can process makefiles.
  - Using clearmake compatibility modes
    clearmake is designed for compatibility with existing make programs, which minimizes the changes you need to make to your makefiles.
  - Using HCL VersionVault to build C++ programs
    Use clearmake effectively with C++ programs built with various compilers.
  - Using HCL VersionVault build tools with Java
    The build behavior of Java tools causes various problems for clearmake. Understand the problems and some possible solutions to resolve them.
  - Setting up a parallel build
    Learn the process to set up and run builds that use several hosts in the local area network.
  - Building software for multiple platforms
    Learn how to address the challenge of using a single source tree to develop an application for a variety of hardware and software platforms.
  - Setting up a build on a non-VersionVault host
    There is a technique to create configuration records for a build that involves HCL VersionVault data, but is performed on a non-VersionVault host.

Build sessions, subsessions, and hierarchical builds

Learn about HCL VersionVault build auditing.

The following terms are used to describe the details of HCL VersionVault build auditing:

Invoking clearmake or clearaudit starts a build session. The time at which the build session begins becomes the build reference time for the entire build session, as described on Continuing to work during a build.
During a build session, one or more target rebuilds typically take place.
Each target rebuild involves the execution of one or more build scripts. (A double-colon target can have multiple build scripts; see How clearmake interprets double-colon rules.)
During each target rebuild, clearmake or clearaudit conducts a build audit.
