Need some help compiling a C++ file

It has been a while since I used C++ and I need some help compiling some source codes.

I have a program that contains about 21 files some of these files are header files and some are .cpp files.

When I try to compile the main.cpp file I get a bunch of error saying it cannot find some of the other files that is needed for the main program to run.

I'm using gcc -o main main.cpp to compile the main program (this is when I get the error).

I also tried to compile all the files together by using gcc -o main *.cpp but I still get some errors.

How can I compile the files in the correct order so I can get it to work? I tried to compile some of the other files that has no MAIN in the code, but I cannot get it to compile, I get an error saying undefined reference to main.

Thank you

isn't it

Code:

---

g++ *.cpp -o main

You'll need to compile all the files together, If it errors with this then paste the errors you get here.

First, you need to learn to differentiate compiler and linker errors. Which ones are you getting?

To compile a cpp file, use g++ -c <filename>. So g++ -c *.cpp should give you a bunch of .o files. If an error occurs during running this command, it's a compiler error and you will have to check for missing include files and possibly include the -I flag in your command.

To link the files to form an executable use g++ -o <name_of_executable> *.o. If you get errors there, you might be missing some cpp files or you will have to link in a library (-l flag).

In any case, post the error message to get more help.
