1. C++和ObjectARX开发一例
2. //-----------------------------------------
3. //开发环境  
4. //vs2008+vs2008sp1+ObjectArx2010+AutoCAD2010  
5. //vs2008新建一个win32项目或者MFC DLL项目  
6. //vs2008设置项目属性->配置->所有配置
7. //vs2008设置项目属性->配置属性->C/C++->代码生成->运行时库=多线程 DLL (/MD)
8. //vs2008设置项目属性->配置属性->C/C++->常规->附加包含目录=E:\AutoCad开发\ObjectARX2010\inc  
9. //vs2008设置项目属性->配置属性->连接器->常规->输出文件=$(OutDir)\$(ProjectName).arx  
10. //vs2008设置项目属性->配置属性->连接器->常规->附加库目录="E:\AutoCad开发\ObjectARX2010\lib-win32"  
11. //vs2008设置项目属性->配置属性->连接器->输入->附加依赖项=rxapi.lib acdb18.lib acge18.lib acad.lib acedapi.lib
