在Visual Studio中预处理后如何查看C / C ++源文件? 10个答案

I want to see the output of the Visual C++ Preprocessor on my code -- i.e., the equivalent of gcc -E. For the life of me, I cannot find the relevant compiler switch. How do I accomplish this?

我想在我的代码上看到Visual C ++预处理器的输出 - 即相当于gcc -E。对于我的生活,我找不到相关的编译器开关。我该如何做到这一点?

#1

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++):

cl.exe,Microsoft Visual C ++的命令行界面,有三个不同的选项用于输出预处理文件(因此在以前的Visual C ++响应中不一致):

• /E: preprocess to stdout (similar to GCC's -E option)

/ E:预处理到stdout(类似于GCC的-E选项)

• /P: preprocess to file

/ P:预处理到文件

• /EP: preprocess to stdout without #line directives

/ EP:没有#line指令的stdout预处理

Project properties -> C/C++ -> Preprocessing -> Preprocess to a file: Yes (/P)

项目属性 - > C / C ++ - >预处理 - >预处理到文件:是(/ P)
