Source Dependency File

Category: Developer Files Format: Text

A D file is a source dependency file generated by GCC, a GNU C compiler. It contains dependencies in plain text that describe the files that were used to create compiled objects (.O files) by a C compiler. D files are generated automatically when the -MMD flag is activated when compiling with GCC.

D files are typically used by GNU Make, a utility used to control the creation of executables and other non-source files of a program. D files may also be opened by any text editor since they store plain text.
