‑M

2.1.78. ‑M

This option instructs the compiler to produce a list of make file dependency lines suitable for use by a make utility.

The compiler executes only the preprocessor step of the compilation. By default, output is on the standard output stream.

If you specify multiple source files, a single dependency file is created.

If you specify the ‑o filename option, the dependency lines generated on standard output make reference to filename.o, and not to source.o. However, no object file is produced with the combination of ‑M ‑o filename.

Use the ‑‑md option to generate dependency lines and object files for each source file.

Example

You can redirect output to a file by using standard UNIX and MS‑DOS notation, for example:

armcc ‑M source.c > Makefile
