github上初始版本是bitcoin-0.1.5,可以从https://github.com/bitcoin/bitcoin下载,但是从网上可以找到更老版本bitcoin-0.1.0,例如可以从如下地址下载:

https://github.com/Dan-McG/bitcoin-0.1.0

网上可以搜到一封关于这个版本的说明邮件,内容如下

Announcing the first release of Bitcoin, a new electronic cash

system that uses a peer-to-peer network to prevent double-spending.

It"s completely decentralized with no server or central authority.

See bitcoin.org for screenshots.

Download link:

http://downloads.sourceforge.net/bitcoin/bitcoin-0.1.0.rar

Windows only for now. Open source C++ code is included.

- Unpack the files into a directory

- Run BITCOIN.EXE

- It automatically connects to other nodes

If you can keep a node running that accepts incoming connections,

you"ll really be helping the network a lot. Port 8333 on your

firewall needs to be open to receive incoming connections.

The software is still alpha and experimental. There"s no guarantee

the system"s state won"t have to be restarted at some point if it

becomes necessary, although I"ve done everything I can to build in

extensibility and versioning.

You can get coins by getting someone to send you some, or turn on

Options->Generate Coins to run a node and generate blocks. I made

the proof-of-work difficulty ridiculously easy to start with, so

for a little while in the beginning a typical PC will be able to

generate coins in just a few hours. It"ll get a lot harder when

competition makes the automatic adjustment drive up the difficulty.

Generated coins must wait 120 blocks to mature before they can be

spent.

There are two ways to send money. If the recipient is online, you

can enter their IP address and it will connect, get a new public

key and send the transaction with comments. If the recipient is

not online, it is possible to send to their Bitcoin address, which

is a hash of their public key that they give you. They"ll receive

the transaction the next time they connect and get the block it"s

in. This method has the disadvantage that no comment information

is sent, and a bit of privacy may be lost if the address is used

multiple times, but it is a useful alternative if both users can"t

be online at the same time or the recipient can"t receive incoming

connections.

Total circulation will be 21,000,000 coins. It"ll be distributed

to network nodes when they make blocks, with the amount cut in half

every 4 years.

first 4 years: 10,500,000 coins

next 4 years: 5,250,000 coins

next 4 years: 2,625,000 coins

next 4 years: 1,312,500 coins

etc...

When that runs out, the system can support transaction fees if

needed. It"s based on open market competition, and there will

probably always be nodes willing to process transactions for free.

该版本是用VC6.0进行编译的,结合源码中的说明文档可知,完成编译还需如下依赖库

wxWidgets http://www.wxwidgets.org/downloads/

OpenSSL http://www.openssl.org/source/

Berkeley DB http://www.oracle.com/technology/software/products/berkeley-db/index.html

Boost http://www.boost.org/users/download/

2 编译依赖库

2.1 编译wxWidgets

初始版本中界面库用的是wxWidgets,这里选用版本wxWidgets-2.8.10,编译时尽量使用和该文中相同的版本,否则可能会有问题,该库编译过程很简单,直接用VC6.0打开图中静态工程wx.dsw,并编译相应的Debug和Release版本即可,如图

2.2 编译OpenSSL

OpenSSL 是一个安全套接字层密码库,囊括主要的加密算法,比特币源码直接使用了该库中的相关加密算法。这里选用的是源码说明文件readme.txt中的版本openssl-0.9.8h.tar.gz,编译OpenSSL需要安装nasm和ActivePerl可参考如下网址

https://www.cnblogs.com/passedbylove/p/5977777.htmlhttps://blog.csdn.net/liangyuannao/article/details/7788004

打开命令行并进入到源码目录,执行如下命令即可完成编译

perl Configure VC-WIN32msdo_ms.batnmake -f mstdll.mak

2.3 编译Berkeley DB

Berkeley DB是一个开源的文件数据库,比特币借助该库实现文件存取,这里选用的版本是db-4.7.25.tar.gz,直接用VC6.0打开图中工程,并编译其中Win32 Debug x86和Win32 Release x86版本

2.4 编译Boost

这里选用版本boost_1_34_1.tar.gz,更新的版本用VC6.0编译会有很多编译错误。(1)生成bjam.exe,打开cmd命令行,进入到boost_1_34_1oolsjamsrc目录下,运行build.bat,build.bat会运行VCVARS32.BAT,设置环境变量,并编译生成bjam,如图

如果系统安装多个VS版本,可以通过注释其他版本来选择VC6.0版本生成bjam.exe

最终会在目录下生成一个名为bin.ntx86的文件夹里面包含一个bjam.exe可执行文件,将其拷贝到boost_1_34_1目录下。

(2)有了bjam之后,运行 bjam --toolset=msvc-6.0进行编译,bjam --toolset=msvc-6.0 install 生成相应的头文件(include)和 库文件(lib),默认生成在C:oost下面。

3 新建VC工程并编译

3.1 新建工程

新建Win32应用工程bitcoin

3.2 添加源码文件

 将源码中的头文件源文件及资源文件添加到新建的工程中

3.3 修改编译选项

将第2节编译好的库文件及相关头文件拷贝到工程目录下(如果不拷贝到工程目录,则添加头文件目录时请填写相应的文件路径),添加相应库头文件路径到附加头文件目录,添加宏定义D__WXMSW__,__WXDEBUG__到预定义中;添加相应的库文件目录到附加文件目录,添加相应的依赖库文件,libeay32.lib libdb47sd.lib wxmsw28d_richtext.lib wxmsw28d_html.lib wxmsw28d_core.lib wxbase28d.lib wxtiffd.lib wxjpegd.lib wxpngd.lib wxzlibd.lib wxregexd.lib wxexpatd.lib kernel32.lib user32.lib gdi32.lib winspool.lib comdlg32.lib winmm.lib shell32.lib comctl32.lib ole32.lib oleaut32.lib uuid.lib rpcrt4.lib advapi32.lib ws2_32.lib,改Code Generation中Use run-time library为Debug Multithreaded DLL,在编译选项中添加/Zm300,否则编译时会有“compiler limit : internal heap limit reached; use /Zm to specify a higher limit”错误提示,在Resources设置下添加附件包含路径include,主要编译设置如下图

 Release版本的编译需要类似的设置,这里不在进行重复说明,已在CSDN上上传了编译好的版本,有需要的可自行下载https://download.csdn.net/download/weiwei22844/10642479!
