如何在make之后运行.o文件

我一直试图从https://github.com/rinon/Simple-Homomorphic-Encryption运行一个c ++程序

正如README我在运行以下命令中指定的那样,

make

make test

make demo

现在,我的目录中有以下文件,

zakirhussain@zakirhussain-K52F:~/Simple-Homomorphic-Encryption$ ls
circuit.cpp             demo_vote_counter.cpp  fully_homomorphic.cpp  main.o                 security_settings.h     test_suite.o  utilities.o
circuit.h               demo_vote_counter.h    fully_homomorphic.h    makefile               security_settings.o     type_defs.h
circuit.o               demo_vote_counter.o    fully_homomorphic.o    README                 test_fully_homomorphic  utilities.c
demo_fully_homomorphic  fully_homomorphic      main.cpp               security_settings.cpp  test_suite.cpp          utilities.h

有人可以帮助我运行demo_vote_counter.o文件吗？
