I see that VC++ includes an option called /show include to list you the hierarchy of include files in each translation unit. This seems to be a very helpful option - to optimise/improve the compilation time in a large scale project.
Question
Is there any equivalent option in GNU g++ compiler to get these (similar output)?
There's a variety of options for controlling this.
-MD will list files, -MMD will list non-system files as side effects of compilation
-M, -MM will generate lists instead of compiling.
-MQ, -MG, -MP and -MT generate makefile target fragments. -MF allows you to specify an output filename.
