Compile the C ++/C file using the command line

Compile the c file using gcc Compile C ++ files (including. C/C ++ files) with G ++

Let's take a look at the common methods for compiling C ++ files:

Single file:

G ++ file. cpp

This is the simplest form. The default output is a. Out. You can use the-O command to specify the output file, such as G ++ file. cpp F. Out.

Multiple files:

G ++-C 1.cpp-O 1.o

G ++-C 2.cpp-O 2.o

G ++ 1.o 2.o-O Prog. Out

 

Link to an executable file:

Generally, G ++-o file. cpp is used.

Multiple files are g ++-o file file1.cpp file2.cpp...

Compile C ++ instead of using gcc but G ++.

If GCC can be compiled but cannot be linked.

 

Multiple files:

1. Compile multiple files without connection:

G ++ file1.cpp file2.cpp

Two files are generated: file1.o and file2.o.

2. Connection:

G ++-O outfilename file1.o file2.o

An executable file named outfilename is generated.

If you want to complete compilation and connection in one step, then:

G ++-O outfilename file1.cpp file2.cpp

-O option controls whether to connect.
