openmpi 代码啥的都没有问题一运行就： -o 报错

ubuntu里面的terminal运行 mpicc hello_par.c –o hello_pargcc 这个代码就出错。 错误：error: –o: No such file or directory

To compile a single file foo.c, use

mpicc -c foo.c

To link the output and make an executable, use

mpicc -o foo foo.o

Combining compilation and linking in a single command
mpicc -o foo foo.c试试这样?
