在Ubuntu上使用g ++编译器运行程序

Question

I need help with running my program on Ubuntu. I have two cpp files and a header file. I get the following error. Can someone help me please.

gopy@gopy-VPCEB36GM:~/Desktop/helo$ g++ -c Sequence.cpp
gopy@gopy-VPCEB36GM:~/Desktop/helo$ g++ -c SequenceTest.cpp
gopy@gopy-VPCEB36GM:~/Desktop/helo$ g++ -o Sequence.o SequenceTest.o test
g++: error: test: No such file or directory

The o files are created when I open the helo folder

Answer 1

g++ man

-o <file>                Place the output into <file>

means test must be right after the -o flag, otherwise linker thinks test is the input

gopy@gopy-VPCEB36GM:~/Desktop/helo$ g++ -o test Sequence.o SequenceTest.o

Answer 2

尝试

g++ -o test Sequence.o SequenceTest.o

Answer 3

As others have mentioned, -o stands for output file name. In this case, g++ assumes Sequence.o as the output file name, SequenceTest.o and test are the files to be compiled or linked. So

g++ -o test Sequence.o SequenceTest.o

is the right way to do this. And, you can do the whole compilation process with a single command.

g++ Sequence*.cpp -o test

Answer 4

The non-answer is 'sudo apt-get codeblocks'. You can spend more time learning C++, and less time mucking with command lines.
