Hey I just have a quick question about makefile's. Is there some way to auto run the executable generated from a makefile?
Like if I just type "make" it will compile and build and automatically execute so I can skip the extra step of ./myExecutable
I have down in my notes:
run: prog1
./prog1
But it doesn't seem to work.
Thanks

If you run make without specifying any targets, it would execute the first target it finds within the Makefile. By convention all
is the name of such a target.
If you make run
a pre-requisite for all
and mark both all
and run
as PHONY targets, you should be good to go.
all: run
run: prog1
./prog1
.PHONY: all run
BTW, I presume you already have some rules for building prog1
in your Makefile, and hence have not included it in the above shown Makefile.
An alternative would be to just invoke make explicitly with the run
target, i.e. execute the following command:
make run
