Memtester make: g++: fatal error: output filename may not be empty

Question

I performed the following steps:

1. Downloaded memtester-4.5.1.tar.gz from https://pyropus.ca./software/memtester/
2. tar zxvf memtester-4.5.1.tar.gz
3. cd memtester-4.5.1
4. make

It gives the following error:

g++: fatal error: output filename may not be empty
compilation terminated.
