Environment files

Environment files define the directory structure of your applications by creating a mapping between the file types known to the MakeTPF build solution and the directories they reside in. These environment files are referenced in makefiles to define where the MakeTPF build solution searches for source files and where output files are written.

This directory structure is defined to the MakeTPF build solution independent from a parent (or root) directory. This enables the MakeTPF build solution to associate the directory structure to one or more root directories at build (assemble, compile, and link) time and provides the capability of concatenating directory structures in much the same way that data sets can be concatenated in JCL.

Environment files are set up by the system administrator based on the hierarchical file system (HFS) structure. The GNU make syntax is used for environment files. See Define the HFS directory structure and environment files for examples of environment files.
