利用SVN实现自动修订版本号生成

自：http://hi.baidu.com/comeon010/blog/item/67c5669bfa759eb8c8eaf42a.html

SVN是当前比较流行的版本控制软件，下面主要介绍通过SVN在程序编译时自动生成版本号。

基本思想：利用SubWCRev.exe获取版本信息，读入屏幕流，生成包括版本号信息的“.H文件”，并修改“.rc资源文件”中的版本信息，“.H文件”主要用于关于框中的版本显示，简单格式如下：

#ifndef __SVN_VERSION_MAX
#define __SVN_VERSION_MAX XXX
#endif

用下面附录的源码编译SVNVersionGen.exe

使用说明：

建立一个批处理文件

setlocal

设置TortoiseSVN安装目录
set SVN_PATH=D:\Program Files\TortoiseSVN\bin  
设置解决方案目录
set WORK_DIR=e:\My Documents\Visual Studio Projects\XXX
设置版本号，前三位
set VERSION_M="1,X,X"
set VERSION_S="1, X, X"

SVNVersionGen -HEADER "%SVN_PATH%" "%WORK_DIR%" "SVNVersion.h"

设置子项目名称
set PRO1_NAME=PROJECT1
SVNVersionGen -RESVERSION "%SVN_PATH%" "%WORK_DIR%\%PRO1_NAME%" "%WORK_DIR%\%PRO1_NAME%\%PRO1_NAME%.rc" %VERSION_M% %VERSION_S%

设置子项目2名称
set PRO1_NAME=PROJECT2
SVNVersionGen -RESVERSION "%SVN_PATH%" "%WORK_DIR%\%PRO1_NAME%" "%WORK_DIR%\%PRO1_NAME%\%PRO1_NAME%.rc" %VERSION_M% %VERSION_S%
endlocal
