This is a collection of the files that I modified in order to get ECC-LIB (version 2.0) to compile on Windows 32. Since ECC-LIB requires the GNU Multiple Precision Arithmetic Library (GMP) you also need my Win32 port of GMP, which can be found at the same place you downloaded this. Also, I have only tested it on a Windows XP machine with MS Visual Studio .NET 2003.
To compile it just copy the files provided here to the distribution directory of ECC-LIB 2.0 and overwrite the existing files there, then simply enter the directory and type nmake. If you don't use MS VS .NET 2003 you would have to change the related include line in the Makefile. There is no installation required, just put all the files from the include directory to your include path and ecc.lib to your library path. When you are using it in MSVC++ to compile new programs don't forget to define NTRG_WIN32, include the relevant header files and link against ecc.lib and gmp.lib.
In the directory bin/ you can find a pre-compiled version.
You can find ECC-LIB at:
