This howto is a step by step guide for building wpa_supplicant in windows with support for TLS. The two main steps described here are how to build openssl and howto configure Microsoft Visual Studio/C++ 2005 for compiling wpa_supplicant.

• Download openssl source files from here
• Configure the environment :

 perl Configure VC-WIN32 --prefix=c:/some/openssl/dir

Where the prefix argument specifies where OpenSSL will be installed to.

• Build the Makefiles and optionally the assembly language files:

  ms\do_masm

• Build and install openssl : From the VC++ environment at a prompt do:

  nmake -f ms\ntdll.mak
  nmake -f ms\ntdll.mak install

• Copy ssleay32.lib to ssleay32Mt.lib and libeay32.lib to libeay32Mt.lib

(This is a dirty workaround because wpa_supplicant requires Mt, but openssl doesnot explain how to compile with Mt )

Download WinPcap from here and unpack it somewhere.

• Open wpa_supplicant/vs2005/wpa_supplicant.sln with VC++ 2005
• Add paths to openssl and winpcap libraries and include files from Tools → Options → VC++ Directories
• For MSVC++ 2005 Express :
  1. Install Microsoft Platform SDK for Windows XP SP2
  2. Add the following in Properties → Configuration Properties → Linker → Input → Additional Dependencies

OleAut32.Lib
AdvAPI32.Lib
Ole32.Lib

ssleay32.dll and libeay32.dll are needed by wpa_supplicant, they can found in out32dll under the openssl build directory.
