make clean

WHen installing software, after compiling by using "make" command, some asks to "make clean". Some does not ask it.
WHat does "make clean" do? Will it cause any problem if I "make clean", when installation instructions don't state to "make clean"? Thanks.

clean is an entry in the makefile.

Read your makefile, look for the 'clean' rules and verifies what it does.

Normally a clean action will remove everything that is build. (e.g objects, programs).

If some installation program asks it, the y normally remove all unneeded files, and just leave executable (and maybe the original sources)
