LINK2001 error

[孙俊博]

I‘m a begginer of objectarx development learner,and I built a new project want to create a simple box ,here is my code 

#include "stdafx.h"
#include "CreateSolids.h"

void CreateSolids::Init() {
    acedRegCmds->addCommand(_T("CreateSolidsCommands"), _T("CreateBox"), _T("CreateBox"), ACRX_CMD_MODAL, CreateBoxFunction);
}

void CreateSolids::Unload() {
    acedRegCmds->removeGroup(_T("CreateSolidsCommands"));
}

void CreateSolids::CreateBoxCommnad() {
    CreateBoxFunction();
}

void CreateSolids::CreateBoxFunction() {
    // box  
    AcDbDatabase* pDb = acdbHostApplicationServices()->workingDatabase();
    AcDbBlockTable* pBlockTable;
    if (pDb->getBlockTable(pBlockTable, AcDb::kForWrite) != Acad::eOk) {
        acutPrintf(_T("Failed to get Block Table.\n"));
        return;
    }

    AcDbBlockTableRecord* pModelSpace = nullptr;
    if (pBlockTable->getAt(ACDB_MODEL_SPACE, pModelSpace, AcDb::kForWrite) != Acad::eOk) {
        acutPrintf(_T("Failed to get Model Space.\n"));
        pBlockTable->close();
        return;
    }

    AcDb3dSolid* pBox = new AcDb3dSolid();
    if (pBox->createBox(10.0, 10.0, 10.0) != Acad::eOk) {
        acutPrintf(_T("Failed to create box.\n"));
        pBox->close();
        pModelSpace->close();
        pBlockTable->close();
        return;
    }

    pModelSpace->appendAcDbEntity(pBox);
    pModelSpace->close();
    pBlockTable->close();
}

How should I solve this.

This new project built by this

[daniel_cadext]

try adding this in your StdAfx.h, or somewhere in your code if you don't have that

#pragma comment( lib , "AcPal.lib" )

I wrote all .lib names into connector-input. and it works
