本文介绍了在Visual Studio中进行预处理后,如何查看C / C ++源文件?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
解决方案
cl.exe
,Microsoft Visual C ++的命令行界面,有三个不同的输出预处理文件的选项(因此,以前有关Visual C ++的响应不一致):
如果要对没有#line指令的文件进行预处理,请将 / P
和 / EP
选项。
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?
解决方案
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 to stdout (similar to GCC's -E option)/P
: preprocess to file/EP
: preprocess to stdout without #line directives
If you want to preprocess to a file without #line directives, combine the /P
and /EP
options.
