Here’s how I get the preprocessed MyActor.cpp:
Find the Compiler Response File “MyProject/Intermediate/Build/Win64/MyProect/Debug/MyActor.cpp.obj.response”.
Find all Preproscessor Definitions under VS2015 project properties ->NMake.
Edit .response file
-
Insert Preproscessor Definitions into .response file
-
Replace the /Fo line with /P
open “VS2015 x64 Native Tools Command Prompt”
cd MyProject/Intermediate/Build/Win64/MyProect/Debug/
cl.exe @MyActor.cpp.obj.response
Then the huge prepocessed c++ file MyActor.i is generated
Use clang-format to beautify it
