如何从c ++运行c ++代码？ [英] How to run c++ code from c++?

问题描述

如果我在c ++程序中有一些c ++代码作为字符串数量（数据），我可以执行该字符串的内容吗？

解决方案

简短答案：不能。

稍长一点的答案：c ++没有反射，一般编译，所以不支持这种类型

>

1. 使用可嵌入的动态语言，如[python | tcl | ruby​​ | ...]与您的c ++代码一致。现在，您需要在数据中使用动态语言（而不是c ++）。


2. 使用c ++解释器，例如 cint 或ch。


3. 使用系统c ++编译器从您的代码构建一个动态库，并链接到它。危险和系统依赖。


4. 使用其他语言。

If I have some c++ code as a string quantity (data) in a c++ program, can I execute the contents of that string?

As using the CodeDOM in C# or the eval function present in perl, python, etc..

解决方案

Short answer: you can't.

Slightly longer answer: c++ has no reflection, and is generally compiled, so there so is no support for this kind of thing, and it can not be easily added..

Work arounds:

1. Use an embeddable dynamic language like [python|tcl|ruby|...] in concert with your c++ code. Now you need to have the dynamic language (rather then c++) in the data.
2. Use a c++ interpreter like cint or ch. This binds you to the interpreter.
3. Use the system c++ compiler to construct a dynamic library from your code and link to it on the fly. Risky and system dependent.
4. Use a different language.
