  - 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.
    - 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.

    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.

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.

Including a version string or time stamp allows anyone (for example, a customer) to determine the exact version of a program by entering a shell command.

The following techniques support the use of the what command or the -Ver option. For example:

% what monet
monet R2.0 Baselevel 1
Thu Feb 11 17:33:23 EST 2003

% monet -Ver
monet R2.0 Baselevel 1 (Thu Feb 11 17:33:23 EST 2003)

After the particular version of the program is determined, you can use HCL VersionVault commands to find a local copy, examine its config record, and if appropriate, reconstruct the source configuration with which it was built. (Presumably, the local copy is a derived object that has been checked in as a version of an element.)

You can identify the appropriate derived object by attaching a HCL VersionVault attribute with the version string to the checked-in executable, or you can rely on the time stamp and your ability to run the what command on the checked-in executable to find it.
