Rebuilding a Makefile

You can have applications with multiple .mf files in your directory, particularly when using the mkmerge command to integrate specific or optional code. When a .mf file is created or changed, you must recreate the Makefile. To check this, create an empty directory, and put a .mf file, a.mf, in it. Type either make Makefiles or make mkmake and you will recreate the Makefile.

If the Makefile changes, the compilation options may have changed. Therefore all object files must be recompiled. When mkmake regenerates a Makefile, if the Makefile has changed, mkmake removes any object files which have been produced. Use the make command now to recompile the source code.
