[Linker Fatal Error] Fatal: Unable to open file 'GRAPHICS.OBJ'

这个错误信息是怎么回事？

这是一个dll程序，用到了Graphics::TBitmap，为了能在没有CB环境的机器上运行，在Project->Options->Packages中将Build with runtime packages的对勾去掉，结果就Link不过了，有这个对勾时是好的，不知为什么？exe好像没有这个问题。

楼主，你的错误应该试你的系统引起的。
具体原因不好说。
因为你的代码正常的机器可以通过。
没有任何错误——除了最初的那个，看看你的短消息把。

依然不行，link错误更多了

在source\vcl目录下生成了graphis.obj，拷贝到工程目录下，在工程中删除graphics.pas，添加graphics.obj，再link，但还是上面的错误，为什么？

然后你再移去那个pas试一试，应该还是能够编译通过，原因就在于你编译以后获得了一个obj文件，以后你的其他工程也可能不再需要添加了。

正如我在2楼所说的，而楼主却没有尝试。

btw：我是看见楼主没有结贴，看一下是不是问题没有解决，我原来以为楼主问题早就应该解决了。

你选择添加文件-〉更改类型为*.pas->转移到目录source下的vcl选择graphics.pas->打开

就可以了，你试一下，不行再找我。

1，需要手工包含什么lib文件，系统的.h或.hpp中都应该包含了吧，因为在一个exe工程中这样使用是没有问题的。
2，已经这样做过了，结果还是一样。
3，没有自动打开的cpp，我都是在Project Manager中选择cpp打开。拷贝到其他目录也一样，只要还是dll工程。

两个都加上了，还是一样。

加上這一句：
#pragma link "jpeg" //或者 vcljpg.lib

程序其实很简单，就是利用cb下的bmp和jpg转化方便做的一个dll（vc下调用方便），工程创建时用的是默认选项：use vcl，options中只是把Build with runtime packages的对勾去掉，其它未改，就link失败了，程序如下：
//---------------------------------------------------------------------------

#include <vcl.h>
#include <windows.h>
#include <JPEG.hpp>
#pragma hdrstop
//---------------------------------------------------------------------------
// Important note about DLL memory management when your DLL uses the
// static version of the RunTime Library:
//
// If your DLL exports any functions that pass String objects (or structs/
// classes containing nested Strings) as parameter or function results,
// you will need to add the library MEMMGR.LIB to both the DLL project and
// any other projects that use the DLL. You will also need to use MEMMGR.LIB
// if any other projects which use the DLL will be performing new or delete
// operations on any non-TObject-derived classes which are exported from the
// DLL. Adding MEMMGR.LIB to your project will change the DLL and its calling
// EXE's to use the BORLNDMM.DLL as their memory manager. In these cases,
// the file BORLNDMM.DLL should be deployed along with your DLL.
//
// To avoid using BORLNDMM.DLL, pass string information using "char *" or
// ShortString parameters.
//
// If your DLL uses the dynamic version of the RTL, you do not need to
// explicitly add MEMMGR.LIB as this will be done implicitly for you
//---------------------------------------------------------------------------

extern "C" __declspec(dllexport) long _stdcall ConvertPic(IN long Mode, IN char *srcData, IN long srcLen, OUT char *tagData, OUT long *tagLen);
#pragma argsused
BOOL WINAPI DllMain(HINSTANCE hinstDLL, DWORD fwdreason, LPVOID lpvReserved)
{
return 1;
}
//---------------------------------------------------------------------------
long _stdcall ConvertPic
(
IN long Mode, //0：JPG->BMP，非0：BMP->JPG
IN char *srcData, //源图片数据
IN long srcLen, //数据长度
OUT char *tagData, //目标图片数据
OUT long *tagLen //数据长度
)
{
long lRet=0;
Graphics::TBitmap *bmp=new Graphics::TBitmap();
TJPEGImage *jpg=new TJPEGImage();

TMemoryStream *ms=new TMemoryStream();
ms->Write(srcData,srcLen);
ms->Position=0;

TMemoryStream *ms1=new TMemoryStream();
try
{
if(Mode==0)
{
jpg->LoadFromStream(ms);
bmp->Assign(jpg);
bmp->SaveToStream(ms1);
}
else
{
bmp->LoadFromStream(ms);
jpg->Assign(bmp);
jpg->SaveToStream(ms1);
}
*tagLen=ms1->Size;
ms1->Read(tagData,*tagLen);
}
catch(Exception &e)
{
//e.Free();
lRet=-1;
}
delete ms1;
delete ms;
delete bmp;
delete jpg;

return lRet;
}
到底是怎么回事呀？？
