从Borland DLL导出C ++类并在Microsoft VC中使用它 [英] Export C++ class from a Borland DLL and use it in Microsoft VC
问题描述
大家好，
我是这个小组的新手，我不知道这是不是正确的小组
我的问题。
我有一个带有导出库（.lib）的DLL在Borland C ++ 6中编写。在
borland一切正常，我能够包含lib并使用
我已经导出的类创建了一个带有new等的实例...我想要在Microsoft VC ++中使用相同的.lib导出这个类。
文件。显然它不起作用。
是否可以生成或转换导入库为
兼容格式？
提前谢谢
法布里

我的问题。
我有一个带有它的DLL导出库（.lib）在Borland C ++ 6中写道。在
borland中，一切正常，我可以包含lib并使用我已导出的
类创建一个带有new等的实例...我想要使用相同的.lib
文件在microsoft VC ++中导出这个类。显然它不起作用。
是否可以生成或转换导入库为
兼容格式？
Nope。
编译的C ++代码没有二进制标准。每个编译器都使用它的b
自己的二进制布局。
这意味着C ++代码在不同的编译器之间是不兼容的，并且即使是不同的编译器版本也是如此。
在msvc中使用Borland C ++ dll是不可能的。
这不是微软的问题btw。所有编译器都是如此。微软
甚至有很好的兼容性记录，gcc最差。
如果要导出C ++代码，你必须坚持使用1个编译器。 br />
如果你想混合不同的编译环境，你必须坚持使用
ANSI C接口。

不正确。
问题显然是关于从dll导出的C ++类。
Of当然，可以使用任何C / C ++编译器创建dll。
但是编译的C ++类在不同的C ++编译器之间是不兼容的。
这无关与微软。这是因为它花了很长时间才使C ++标准化，而不同的供应商花了很多时间来做自己的事情。
Borland与microsoft不兼容与gcc不兼容
与icc不兼容是...与C ++类不相容
关注。
DLL使用本身没问题。问题是，那个dll里面的内容不是一个类，因为msvc会编译它。
因此，它不起作用。

Hi All,
I''m new of this group and I do not know if this is the correct group
for my question.
I have a DLL with its export library (.lib) wrote in Borland C++ 6. In
borland everything is OK and I am able to include the lib and use the
class that i have exported creating an instance with new etc... I
would like to export this class in microsoft VC++ using the same .lib
file. Obviously it doesn'' t work.
Is it possible to generate or convert the import library into a
compatible format?
Thank you in advance
Fabry

There is no binary standard for compiled C++ code. Each compiler uses its
own binary layout.
This means that C++ code is incompatible between different compilers, and
even different compiler version.
Using Borland C++ dlls in msvc is not possible.
This is not a Microsoft problem btw. It is true for all compilers. Microsoft
even has a very good record for compatibility, gcc the worst.
If you want to export C++ code you have to stick with 1 compiler.
If you want to mix different compiler environments, you have to stay with
ANSI C interfaces.

language independant. If it really doesn''t work with the MS compiler (I
did not do this), it is in fact a Microsoft problem.

The question is clearly about C++ classes that are exported from a dll.
Of course, dlls can be created with any C/C++ compiler.
But compiled C++ classes are NOT compatible between different C++ compilers.
This has nothing to do with Microsoft. It is a result from the fact that it
took a very long time for C++ to be standardized, while different vendors
went along, doing their own thing.
Borland is incompatible with microsoft is incompatible with gcc is
incompatible with icc is incompatible with ... as far as C++ classes are
concerned.
DLL usage itself is no problem. The problem is that what''s inside that dll
is not a class as msvc would have compiled it.
Hence, it does not work.
