Visual Studio 2008 IDE - 静态链接 C Dll 库
我正在经历挫败感 ^ 挫败感与这个 %&$^& VS IDE。 我正在使用 Visual C++ 2008 3.5 SP1(但如果需要的话我也有专业版,并且我不想使用 loadlibrary())
我有一个用另一种语言(实际上不是 C)创建的测试 Dll,其中包含 CDECL将“int”添加到“double”的函数。我真的很想使用 STDCALL 将 int 添加到 float,但如果能让前者首先工作,那将是一项重大成就。
我广泛阅读并尝试过: http://support.microsoft.com/kb/313981 http://www.codeproject.com/KB/DLL/loadingdll.aspx 链接到静态库,该静态库链接到静态库库 静态和动态链接使用不同版本生成的 DLL Visual Studio
我为 AddShow.dll 编写了一个很好的头文件,名为 AddShow.h
DLLAPI int __cdecl AddTwoNum(int n, double f);
然后我使用这个漂亮的工具来创建 .lib 文件: http://www.binary-soft.com/dll2lib/dll2lib.htm
现在怎么办?
我尝试右键单击“添加”,然后“类”,然后“组件类”,然后指定 dll 的路径和名称,但我得到了 8 英里的膨胀和整个 Windows 工具箱以及一个新的 AddShow.cpp 文件。
我的 C++ 代码非常简单:
extern int __cdecl AddTwoNum(int n, double f);
int main()
{
int n, RetVal;
double d;
n = 33;
d = 66.6;
RetVal = AddTwoNum(n, d);
cout << "RetVal=" << RetVal;
return 0;
}
如何让 IDE 链接 .lib 文件
?
after linking (.lib file is in the debug file) I get the following error:
Compiling...
main.cpp
Linking...
main.obj : error LNK2019: unresolved external symbol "int __cdecl AddTwoNum(int,double)" (?AddTwoNum@@YAHHN@Z) referenced in function _main

I am experiencing Frustration ^ Frustraion with this %&$^& VS IDE.
I am using Visual C++ 2008 3.5 SP1 (but I also have the pro edition if that is needed and I dont want to use loadlibrary())
I have a test Dll created in another language (basic not C in fact) that contains a CDECL function that adds an 'int' to a 'double'. I would really like to add an int to a float using STDCALL, but if can get the former to work first that would be a major acheivement.
I have read extensively and tried:
http://support.microsoft.com/kb/313981
http://www.codeproject.com/KB/DLL/loadingdll.aspx
Linking to a static lib that links to a static lib
statically and dynamically linking DLLs generated with different versions of Visual Studio
I wrote a nice header file for the AddShow.dll called AddShow.h
DLLAPI int __cdecl AddTwoNum(int n, double f);
Then I used this nifty tool to create the .lib file:
http://www.binary-soft.com/dll2lib/dll2lib.htm
Now what?
I tried right click and 'Add' then 'Class" then 'Componant Class' then specifying the path and name of the dll, but I get 8 miles of bloat and the entire windows toolbox and a new AddShow.cpp file.
My C++ code is really simply:
extern int __cdecl AddTwoNum(int n, double f);
int main()
{
int n, RetVal;
double d;
n = 33;
d = 66.6;
RetVal = AddTwoNum(n, d);
cout << "RetVal=" << RetVal;
return 0;
}
How do I just get the IDE to link the .lib file?

您可以前往:
然后将您的.lib 添加到“附加依赖项”中。
此外,您可以放入
.cpp 文件。
You can go to:
Then add your .lib to the "Additional Dependencies".
Additionally, you can put
in your .cpp file.
