  7  1. Install mxe (check tutorial on http://mxe.cc)
  8  
  9  2. After install mxe
 10  export PATH={PATH_TO_MXE}/usr/bin:$PATH
 11  autoreconf -fi
 12  ./configure --host=i686-pc-mingw32 --enable-blockerupter --without-curses CFLAGS=-DCURL_STATICLIB
 13  make
 14  
 15  3. Before starting cgminer
 16  install WinUSB driver for detected CP2102x device with Zadig (Some users might need to reboot)
