Help me with some simple makefile scripting

[manasij7479]

I wan't to make the makefile in such a way that if I invoke the make command with an extra flag... say (-g) , it will be somewhat like

#ifdef g
gdb main
#else
./main
#endif

I don't know how to correlate it.

You can't provide your own flags to make. Maybe there are some user definable flags, but I doubt it.

Why don't you just use different targets for this purpose?

Didn't think of that, in a fit of confusion.
It is a perfect solution.
Thank You.
