方法二 通過預處理方式
轉載自：
1.編寫版本模板文件svn_revision_template.h
1 #ifndef _SVN_REISION_H_ 2 #define _SVN_REVISION_H_ 3 #define AMG_LIB_VER_SVN_VERSION "$WCREV$" 4 #endif // !_SVN_REISION_H_
注意$WCREV$這里不能修改
2.新建版本文件svn_revision.h
1 #ifndef _SVN_REISION_H_ 2 #define _SVN_REVISION_H_ 3 #define AMG_LIB_VER_SVN_VERSION "1267" 4 #endif // !_SVN_REISION_H_
3.通過預先生成事件，添加下面的批處理命令
subwcrev.exe .\ .\svn_revision_template.h .\svn_revision.h
注意第一個參數.\ 指需要獲取哪個路徑的svn號碼
第二個參數.\svn_revision_template.h 指模板文件路徑
第三個參數.\svn_revision.h 指修改后文件保存路徑
4.代碼中使用：直接使用.\svn_revision.h文件中的宏
AMG_LIB_VER_SVN_VERSION
