Visual C ++编译

[英]Visual C++ Compilation

原文 2012-10-07 18:37:21 7 2 .net/ visual-c++

All of my commercial experience is based on high level languages like .NET (VB and C#). 我所有的商业经验都基于.NET（VB和C＃）等高级语言。 I have academic experience with C and C++ (university). 我具有C和C ++（大学）的学术经验。

I don't full understand how Visual C++ fits into the .NET way. 我不完全了解Visual C ++如何适合.NET方式。 I have experience using Cygwin to compile c++ programs for Linux (at university). 我有使用Cygwin编译Linux上的c ++程序的经验（在大学里）。

Am I correct in stating that Visual C++ will compile into Intermediary language like C# and VB.NET? 我是否正确地说Visual C ++可以编译为C＃和VB.NET之类的中介语言？ I assume that Visual C++ is used by developers that want to target Windows only and Cygwin is used by C++ developers who want to target multiple environments? 我是否假定Visual C ++由仅用于Windows的开发人员使用，而Cygwin由C ++针对多个环境的开发人员使用？

The reason I ask is because I am using a C++ component (written by another developer) as part of a .NET app. 我问的原因是因为我将C ++组件（由其他开发人员编写）用作.NET应用程序的一部分。

I have read many Visual C++ articles online today but I have not yet found the answer I am looking for. 我今天在网上阅读了许多Visual C ++文章，但尚未找到所需的答案。

2 个解决方案

No. C++ is compiled directly to machine code, there is no intermediate step like .NET's IL with a just-in-time compiler to translate it to machine code at runtime. 不会。C++是直接编译为机器代码的，没有像.NET的IL那样的中间步骤，而只有即时编译器才能在运行时将其转换为机器代码。

If you have a need to interop between C++ and .NET code then you'll probably want to take a look at C++/CLI. 如果您需要在C ++和.NET代码之间进行互操作，那么您可能需要看一下C ++ / CLI。 A language that merely resembles C++ but is very good at bridging the gap between native C++ and the .NET runtime. 一种仅类似于 C ++但非常善于弥合本机C ++与.NET运行时之间的鸿沟的语言。

Am I correct in stating that Visual C++ will compile into Intermediary language like C# and VB.NET? 我是否正确地说Visual C ++可以编译为C＃和VB.NET之类的中介语言？

Yes and no. 是的，没有。 If you use C++/CLI (which is a Microsoft proprietary language included in Visual C++, similar to the C++ language but definitely not the same thing), then yes, it will compile to .NET intermediate code. 如果使用C ++ / CLI（这是Visual C ++中包含的Microsoft专有语言，类似于C ++语言，但绝对不是同一件事），那么可以，它将编译为.NET中间代码。 If you turn off C++/CLI and use standard C++, then it will compile to native code and not use the .NET runtime. 如果关闭C ++ / CLI并使用标准C ++，则它将编译为本机代码，而不使用.NET运行时。

Cygwin is used by C++ developers who want to target multiple environments? Cygwin由想要针对多个环境的C ++开发人员使用？

Cygwin is not required if you want to target multiple environments. 如果要定位多个环境，则不需要Cygwin。 However, code written in a portable way that compiles with Cygwin is more likely to compile on GCC on other platforms too. 但是，以Cygwin编译的可移植方式编写的代码也更有可能在其他平台的GCC上编译。 You can write portable code with any compiler. 您可以使用任何编译器编写可移植代码。

Cygwin to compile c++ programs for Linux Cygwin将为Linux编译C ++程序

I think you might be a wee bit confused on this point. 我认为您可能会对此感到困惑。 Cygwin is a package that provides a GCC compiler (and POSIX-like) environment for Windows . Cygwin是一个软件包，为Windows提供了GCC编译器（和POSIX类似）环境。 Cygwin does not run on Linux, there's no need. Cygwin不在Linux上运行，没有必要。
