# Hey Emacs, this is a -*- makefile -*-## WinARM template makefile # by Martin Thomas, Kaiserslautern, Germany # <eversmith@heizung-thomas.de>## based on the WinAVR makefile written by Eric B. Weddington, J鰎g Wunsch, et al.# Released to the Public Domain# Please read the make user manual!### On command line:## make all = Make software.## make clean = Clean out built project files.## make program = Download the hex file to the device, using lpc21isp## (TODO: make filename.s = Just compile filename.c into the assembler code only)## To rebuild project do "make clean" then "make all".## Changelog:# - 17. Feb. 2005  - added thumb-interwork support (mth)# - 28. Apr. 2005  - added C++ support (mth)# - 29.
