2.9 Compilation information

A file named klib/version.h will be generated every time make generates a new system image. It will contain definitions for these symbols:

• OFF_VERSION, a string with the source code version identifier (as reported by cvs).
• OFF_COMPILE_DATE, a string with the date the compilation was started.
• OFF_COMPILE_TIME, a string with the time the compilation was started.
• OFF_COMPILE_BY, a string with the user name for the user who started the compilation.
• OFF_COMPILE_HOST, a string with the name of the host the kernel was compiled in.
• OFF_COMPILER a string with the name of the C++ compiler used. \item OFF_ARCHa string with the name of the architecture the kernel was built for.
• OFF_URL a string with the root of the web site where literate sources for this kernel version are kept.

They will be kept in a static object containing those strings. Its intend is to keep them inside each system image.
