g ++错误没有这样的文件或目录

Question

I keep getting this error when I try to compile a .cpp file in my unix terminal.

Here is my command:

-bash-4.2$ g++ -o test.cpp test

Output:

g++: error: test: No such file or directory
g++: fatal error: no input files
compilation terminated.

But, when I type in ls :

test.cpp

Do I have the wrong version of g++?

Answer 1

Your command line is wrong. Try this

g++ -o test test.cpp

The syntax is -o <output-file> , but you had your input file listed there, so g++ was looking for test as an input file.
