miracl-大数运算库,大家使用有什么问题请多多提意见

To create MIRACL applications under Microsoft Windows using Microsoft C++ 
version 6.0, follow these steps. Remember a "Release" build will be 
faster than a "Debug" build. For MS VC++ .NET see below.


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/zzn.cpp etc. Those required are 
   specified in the comments at the start of the main project file, e.g.
   * Requires: big.cpp zzn.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.

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

1. Click on New and Project, and select "Visual C++ Projects", "Win32",
   select "Win32 Console Project", and give the project name, for example
   limlee, for the limlee.cpp example. Click on Finish.

2. Now things get a little tricky. An empty limlee.cpp file is provided.
   You must now cut and paste from the Miracl provided file limlee.cpp into
   this one. Note that the main program is now called _tmain.

3. Click on Project, and on "Add existing Item", and Select "All files" from 
   the "Files of type" drop-down list.
   Look for the precompiled MIRACL library file ms32.lib, and insert it 
   into the project.

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

5. Click on Project and then "Properties". Open up the C++ Tab, go to "Precompiled 
   Headers", and select "Not using precompiled headers" from the drop-down box.
   Open the "General" Tab, and specify a path to the miracl header files, mirdef.h,
   miracl.h and big.h etc.

6. Build the project and run it by clicking "Debug" and "Start". The program runs 
   to completion and exits.  



To create a new version of the MIRACL library, first create a suitable 
mirdef.h as above, then

1. Click on New and Project, and select "Visual C++ Projects", "Win32", 
   enter the name Miracl  and click on "Win32 Project" and then OK.

2. Click on "Application Settings", and then select "Static Library". 
   Then click on Finish 

3. Add in the appropriate files mr*.c. (Project followed by "Add Existing Items").

4. Click on Project and then "Properties". Open up the C++ Tab, go to "Precompiled 
   Headers", and select "Not using precompiled headers" from the drop-down box.
   Open the "General" Tab, and specify a path to the miracl header files, mirdef.h
   and miracl.h

5. Now build the project.

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
