-/** \page Page_BuildSystem The LUFA Build System

- *

- *  \section Sec_BuildSystem_Overview Overview of the LUFA Build System

- *  The LUFA build system was originally an attempt at making a set of

- *  re-usable, modular build make files which could be referenced in a LUFA

- *  powered project, to minimize the amount of code required in an

- *  application makefile.

- *

- *  As it turned out to be fairly generic in nature, it was split out into its

- *  own separate project, called DMBS (<i>Dean's Makefile Build System</i>)

- *  which is released into the public domain. LUFA-specific portions of the

- *  LUFA build system extend DMBS, and provide a universal build system for all

- *  LUFA projects.

- *

- *  The latest DMBS project information and documentation can be found at:

- *  https://github.com/abcminiuser/dmbs

- *

- *  DMBS is written in GNU Make, and each module is independent of one-another.

- *

- *  LUFA now uses DMBS for its build system, with some LUFA specific extension

- *  modules.

- *

- *  If you have problems building using LUFA, see \subpage Page_BuildTroubleshooting for resolution steps.

-/** \page Page_BuildTroubleshooting Troubleshooting Information

- *

- *  LUFA uses a lot of advanced features of the AVR-GCC compiler, linker, and

- *  surrounding binaries. This can sometimes lead to problems compiling

- *  applications if one of these features is buggy in the version of the tools

- *  used in a build environment. Missing utilities and incorrectly set makefile

- *  configuration options can also result in different errors being produced

- *  when compilation or other operations are attempted. The table below lists a

+ *  LUFA uses a lot of advanced features of the AVR-GCC compiler, linker, and
+ *  surrounding binaries. This can sometimes lead to problems compiling
+ *  applications if one of these features is buggy in the version of the tools
+ *  used in a build environment. Missing utilities and incorrectly set makefile
+ *  configuration options can also result in different errors being produced
+ *  when compilation or other operations are attempted. The table below lists a
+ *  set of commonly encountered errors and their resolutions.
