How do I compile and run a VHDL program on Mac with ghdl?

Question

i just wrote a simple VHDL program. I saved the file as a .vhd file. Then I compiled it with

ghdl -a test.vhd

and then built and executable file with

ghdl -e test

And finally tried to run it with

ghdl -r test

What happened is that I now have a work-obj93.cf file that is visible and two other files, namely .. and . that are somehow invisible.

Can someone tell how exactly I can test a vhdl program on my Mac? Maybe in in combination with GTKWave.
