6. Other useful make targets

There are some other useful targets defined in the top level Makefileof 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 [email protected] .
