The 'win32' target allows projects to be built using two different toolchains: 1. GCC / Cygwin Start your build from a Cygwin Shell and set TARGET=win32 to use this toolchain. The result will be similiar to the 'minimal-net' target. The advantage of 'win32' over 'minimal-net' is the support for GUI applications using the Contiki Toolkit (CTK). For this reason several projects in the /examples directory are built in the target 'win32' by default. 2. VC++ / GnuWin Start your build from a VC++ Command Prompt and set TARGET=win32 to use this toolchain. You need however a few addional tools in your PATH: - cp.exe / rm.exe (http://gnuwin32.sourceforge.net/packages/coreutils.htm) - make.exe (http://gnuwin32.sourceforge.net/packages/make.htm) - sed.exe (http://gnuwin32.sourceforge.net/packages/sed.htm) - makedepend.exe (http://llg.cubic.org/docs/vc7.html)
