====== Cross-compiling wpa_supplicant for windows ======

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








===== Steps =====


   * Install winpcap devel package
     * Get it from   [[http://www.winpcap.org/install/bin/WpdPack_4_0_2.zip|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.


  * Apply this little patch to "driver_ndis_.c"

  * make all


  * Using the binary : The winpcap runtime dlls must be installed before running wpa_supplicant under windows.
