zlib鏈接錯誤

Question

我下載了最新的zlib1.2.5軟件包，並將zlib的根目錄添加到C++ builder include path/lib path，並嘗試編譯以下代碼 ，但在compress，compressBound和uncompress方法中給出鏈接錯誤！

[ILINK32 Error] Error: Unresolved external '_compressBound' referenced from C:\USERS\Dev\DOCUMENTS\RAD STUDIO\PROJECTS\DEBUG\UNIT1.OBJ 

[ILINK32 Error] Error: Unresolved external '_compress' referenced from C:\USERS\Dev\DOCUMENTS\RAD STUDIO\PROJECTS\DEBUG\UNIT1.OBJ 

[ILINK32 Error] Error: Unresolved external '_uncompress' referenced from C:\USERS\Dev\DOCUMENTS\RAD STUDIO\PROJECTS\DEBUG\UNIT1.OBJ 

[ILINK32 Error] Error: Unable to perform link 

// What else dirs do I need to add to lib path??? 
#include <vcl.h>

{ 
    AnsiString astrTemp = ""; 
    // astrTemp = Memo1->Text; 
    unsigned long iLen = mmo1->Text.Length(); //原Memo2 
    unsigned long ulBuflen = compressBound(iLen); // 

    char *pcompress = new char[ulBuflen]; 
    memset(pcompress,'\0',ulBuflen); 

    int iRet = compress(pcompress,&ulBuflen,AnsiString(mmo1->Text).c_str(),iLen); 
    if(iRet == Z_OK) 
    { 
     AnsiString astrTemp=""; 
     for(int i=0;i<ulBuflen;i++) 
     { 
      astrTemp+=IntToHex((unsigned char)pcompress[i],2)+" "; 
     } 
     mmo1->Lines->Add(astrTemp); 
    } 


    astrTemp.SetLength(iLen); 
    uncompress(astrTemp.c_str(),&iLen,pcompress,ulBuflen); 
    mmo2->Text = astrTemp; 

    delete []pcompress; 
}

糟糕！我忘了做他們。 使用make -f win32/Makefile.bor它完成了！

到目前爲止工作正常!!!! 另外，不要忘記添加依賴關係！
