Cross-compiling wpa_supplicant for windows

This is a howto for compiling the ope-source WPA2 supplicant 'wpa_supplicant' for the Windows OS.

• Install winpcap devel package
  • Get it from here
  • unpack it into a folder (../pcap)

• Install mingw
  • apt-get install mingw32*

• wpa_supplicant .config file must contain :

 CFLAGS += -I../pcap/Include -L../pcap/Lib
 CONFIG_CTRL_IFACE=y
 CONFIG_DRIVER_NDIS=y
 CONFIG_NATIVE_WINDOWS=y
 CFLAGS += -I/usr/i586-mingw32msvc/include/
 LIBS += -L/usr/i586-mingw32msvc/lib  -L../pcap/Lib/
 CONFIG_ELOOP=eloop_win
 CONFIG_OS=win32
 CONFIG_EAP_MD5=y

Note that we only compiled the EAP-MD5 method. Other methods may require OpenSSL library to be installed. Future revisions of this howto will include procedures for compiling other EAP methods.
