6. Other useful make targets

There are some other useful targets defined in the top level Makefile of XFree86:

• Everything after a make World, make Everything does everything a make World does, except the cleaning of the tree. It is a way to quickly rebuild the tree after a source patch, but it is not 100% bullet proof. There are cases were it is better to force a full build by using make World.
• clean does a partial cleaning of the source tree. Removes object files and generated manual pages, but leaves the Makefiles and the generated dependencies files in place. After a make clean you need to re-run

          make includes
          make depend
          make
  

  to rebuild the XFree86.
• distclean does a full cleaning of the source tree, removing all generated files. After a make distclean, make World is the only option to rebuild XFree86.
• includes generates all generated header files and in-tree symbolic links needed by the build. These files are removed by a make clean.
• depend recomputes the dependencies for the various targets in all Makefiles. Depending on the operating system, the dependencies are stored in the Makefile, or as a separate file, called .depend. This target needs the generated include files produced by make includes.
• VerifyOS displays the detected operating system version. If the numbers shown do not match your system, you probably need to set them manually in host.def and report the problem to XFree86@XFree86.org .
