我怎么看后在Visual Studio preprocessing一个C / C ++源文件？ [英] How do I see a C/C++ source file after preprocessing in Visual Studio?

问题描述

让我们说我有许多preprocessor指令源文件。是否有可能看到它的外观了preprocessor用它做后？

Let's say I have a source file with many preprocessor directives. Is it possible to see how it looks after the preprocessor is done with it?

推荐答案

cl.exe时，命令行界面到Microsoft Visual C ++，具有输出的三个不同的选项preprocessed文件（因此有关Visual C中的previous回应++的不一致性）：

cl.exe, the command line interface to Microsoft Visual C++, has three different options for outputting the preprocessed file (hence the inconsistency in the previous responses about Visual C++):

• / E ： preprocess到stdout （类似于GCC的-E选项）


• / P ： preprocess到文件


• / EP ： preprocess到stdout没有#line指令

• /E: preprocess to stdout (similar to GCC's -E option)
• /P: preprocess to file
• /EP: preprocess to stdout without #line directives

如果您想preprocess到一个文件中没有#line指令，结合 / P 和 / EP 选项。

If you want to preprocess to a file without #line directives, combine the /P and /EP options.
