Lesson Summary

A thorough understanding of the build system can help to decrease development time and therefore project costs. You must know the steps performed during each phase of the build process if you want to test source code changes quickly and without unnecessary compilation cycles. You must also know the purpose and location of the run-time image configuration files, such as .reg, .bib, .db, and .dat files, to create and maintain OS designs efficiently.

The Windows Embedded CE build system combines the various .reg, .bib, .db, and .dat files during the Make Run-time Image phase into consolidated files that the build system then uses to configure the final run-time image. It is a good idea to check these files if you want to verify that a specific setting or file made it into the final image without having to load the run-time image on the target device. You can find the various run-time image configuration files in the release directory of the OS design. If you discover that expected entries are missing, check the conditional statements and the environment variables and SYSGEN variables defined in your catalog items.

The build system creates the following run-time image configuration files during the Make Run-time Image phase:

? Reginit.ini Combines the Platform.reg, Project.reg, Common.reg, IE.reg, Wceapps.reg, and Wceshell.reg files.

? Ce.bib Combines the Config.bib, Platform.bib, Project.bib, and Subproject bib files.

? Initdb.ini Combines the Common.db, Platform.db, and Project.db files.

? Initobj.dat Combines the Common.dat, Platform.dat, and Project.dat files.
