how to get the source file after the preprocessor of compiler is done with it ?

Development Programming & Scripting C++

there are many preprocessor directives used in source code of UE4 . Is it possible to see how it looks after the preprocessor is done with it ?

Use cl.exe, the command line interface to Microsoft Visual C++
/E: preprocess to stdout
/P: preprocess to file
/EP: preprocess to stdout without #line directives

I didn’t try it myself, but i think this should work.

Thank you,But I use the solution file generated by the “GenerateProjectFiles.bat” to drive the building processing,when I open the properties setting of projects,there is no place to change the setting,how can i change the building setting?
