大数运算库miracl。有了miracl这样的函数库

To create MIRACL applications under Microsoft Windows using Microsoft C++ 
version 6.0, follow these steps.


1. Create a new empty project of type "Win32 Console Application"
   Give it the name of the associated main project file, e.g. limlee 
   for limlee.cpp

2. Click on "Project", and then on "Add to Project", and then on "Files"

3. Select "library files (.lib)" from the "Files of type" drop-down list.
   Look for the precompiled MIRACL library file ms32.lib, and insert it 
   into the project.

4. Add the main project file (e.g.limlee.cpp) into the project.

5. Only if it is a C++ main project file, also add into the project any
   other needed files, like big.cpp/monty.cpp etc. Those required are 
   specified in the comments at the start of the main project file, e.g.
   * Requires: big.cpp monty.cpp
   This step is not required for C projects.

6. Now click on "Project" and then on "Settings". Click the C/C++ tab and 
   select the "preprocessor" category. Find the box "Additional Include 
   Directories", and specify a path to the miracl header files, 
   mirdef.h/miracl.h/big.h etc..

7. Make sure that any files needed by the application are available in the
   directory from which the application is run. For example *.key *.dss, 
   or *.ecs files

8. Now build and run the project.



To create a new version of the MIRACL library, 

1. Compile and run the config.c utility, and rename the generated mirdef.tst 
   to mirdef.h 
   Note that Microsoft C has a 64-bit integer data type called __int64

2. Create a new project of type "Win32 Static Library". Then click on "Finish".

3. Add in the appropriate files mr*.c. The ones required are those listed in 
   miracl.lst (also generated by the config utility).

4. Now click on "Project" and then on "Settings". Click the C/C++ tab and 
   select the "preprocessor" category. Find the box "Additional Include 
   Directories", and specify a path to the miracl header files
   mirdef.h and miracl.h

5. Now build the project and create the MIRACL library.



If using MIRACL within an MFC based Win32 project, here are some hints.

1. Build a MIRACL library with MR_NO_STANDARD_IO defined in mirdef.h
   The config.c utility can be used as usual to create a suitable mirdef.h

2. If using the C++ MIRACL classes, don't forget to change the default project
   settings for the MIRACL implementation files such as big.cpp to "not using 
   pre-compiled headers".  

3. Don't forget that MIRACL is a C library, not C++. To call MIRACL routines 
   directly from a C++ program you must:-

   extern "C"
   {
        #include <miracl.h>
   }

   If using C++, its probably preferable to access MIRACL via the C++ wrapper 
   classes such as implemented by big.h/big.cpp. See big.h file for more tips.

4. To display a big number, convert it first to a string. See the comments at 
   the start of big.h
