DLL 我用了TBitmap ，编译时通不过

[lovezhou]

我用了TBitmap ，编译时通不过，当然在 Build with runtime package 选定时没问题，如果没有选，编译时所有和TBitmap有关的的都要报错了，请问这是为什么呢？

extern "C"
{
int WINAPI __export getfontwidth(LPSTR outstr, LPSTR lfFaceName,
short int lfOrientation, short int lfHeight,
short int lfWidth, short int lfBold, short int lfItalic)
{
int x,y,ByteLength,width,height;
AnsiString outText;
outText = AnsiString(outstr);
Graphics::TBitmap *pBitmap = new Graphics::TBitmap();
Byte *ptr;
pBitmap->Canvas->Font->Name = lfFaceName;
pBitmap->Canvas->Font->Height = lfHeight;
pBitmap->Height = pBitmap->Canvas->TextHeight(outText);
pBitmap->Width = pBitmap->Canvas->TextWidth(outText);
pBitmap->PixelFormat = pf8bit;
pBitmap->Canvas->TextOutA(0,0,outText);
int firstColum = 0;
int count = 0;
for (x = 0; x < pBitmap->Width ; x ++)
{
bool isLineEmpty = true;
for (y = 0; y < pBitmap->Height ; ++ y)
if (pBitmap->Canvas->Pixels[x][y] == 0)
{
isLineEmpty = false;
break;
}
if ((firstColum == 0) && (!isLineEmpty))
{
firstColum = x;
}
if ((firstColum != 0)&& (!isLineEmpty))
{
++ count;
}
}
return (count);
}
}

也就是说，我编的这个DLL在安装过BCB的环境中就没问题但到别的机器上就得带VCL60。BPL等一大堆运行库了，怎么办呢？

报什么错啊？你不写别人怎么知道什么错啊？提问时应该将问题描述清楚。

要么是工程（Project）有问题，要么是BCB有问题。你新建一个Project，然后将各个cpp
加到Project中再Build看看。

找到TImage定义的LIB文件，加到工程中，应该没问题啦

我看了下LIB目录什么也看不出来，怎么办有资料吗？

　　这个我知道！
　　在project菜单里有个options选项,运行它在页面上选择packages项把Build with runtime packages的勾去掉,在在页面上选择Linker项,将use dynamic Rtl的勾去掉就可以了。对了，你可不能使用BDE数据库哦，用了那东东只好BCB的安装向导了。

#include <graphics.hpp>

早已加在上面了不行的，
我试过IniFile 之类，就没问题

我就是这样试不行，才只好考那些运行库的，动态库这样编译好象有问题我试了两台机了
