紧急求助！

eCaos

由于程序中计算公式的日益庞大，最近本人想将原来用Vlisp开发的一个程序用ObjectARX改写，就找了一本ARX的书，调试了其中一个程序，编译都通过了，可连接却出了10个错误。
源程如下：
void CrCircle(void)
{
        AcDbBlockTable *pBlockTable;
        AcGePoint3d center(50.0,70.0,0.0);
        AcGeVector3d normal(0.0,0.0,1.0);
    AcDbCircle *pCircle = new AcDbCircle(center,normal,90.0);
   
        acdbHostApplicationServices()->workingDatabase()
        ->getSymbolTable(pBlockTable, AcDb::kForRead);
        AcDbBlockTableRecord*pBlockTableRecord;
        pBlockTable->getAt(ACDB_MODEL_SPACE,pBlockTableRecord,AcDb::kForWrite);
        pBlockTable->close();

        AcDbObjectId circleId;
        pBlockTableRecord->appendAcDbEntity(circleId,pCircle);
        pBlockTableRecord->close();
        pCircle->close();
}
出错内容：

请各位大虾拉我一把，先谢！

从出错信息看,你连接的库文件不全或连接库路径不正确.作为一个
C程序员,这类错误是非常常见也非常容易解决的,看来你是一位C新手.

说实话，VC库文件连接设置并不是一件很容易的工作，不过ObjectARXWiz向导可以帮助你做这些事。
在你下载的ARX中应该的这样的目录：ObjectARX xxxx/utils/ObjARXWiz，在未启动VC时，运行其中的WizardSetup.exe，然后启动VC，新建文件选项中会多一个ObjectARX应用程序项目，选择它并根据你的程序需要按照向导建立工程。在向导添加的"工程名.cpp"文件尾添加代码，这样一般不会出现连接库文件缺少错误。
