Sublime Text不能在C ++中编译多文件项目 [英] Sublime Text not compiling multi-file projects in C++

问题描述

我是编译多文件C ++程序，并有以下错误：

I am to compile a multi-file C++ program, and have the following error;

Undefined symbols for architecture i386:
  "included::printMSG()", referenced from:
      _main in ccQwMj1l.o
ld: symbol(s) not[Finished in 0.3s with exit code 1] found for architecture i386
collect2: ld returned 1 exit status

我的代码：
main.cpp ： https://gist.github.com/3845822

included.cpp： https://gist.github.com/3845825

included.cpp: https://gist.github.com/3845825

included.h： https://gist.github.com/3845827

included.h: https://gist.github.com/3845827

（已确认可使用 g ++ ）

编辑：我不是把这些文件放在一个项目，他们只是在同一个文件夹，我正在编译 main.cpp

I am not putting these files in a project, they are just all in the same folder, and I'm compiling main.cpp

推荐答案

您不能只编译一个文件，希望所有其他文件自动链接到它，以创建最终的程序。

You can't just compile a single file and hope all other files are automatically linked to it to create the final program.

一种方法是使用一个名为 make ，它读取一个 Makefile ，其规则为 code>跟随`。

One way to make that happen is to use a program called make, which reads a Makefile that has rules that make follows`.

一个简单的 Makefile 可以是这样：

A simple Makefile can look like this:

CXXFLAGS = -Wall -g

my_pogram: main.o other_file.o third_file.o
    g++ main.o other_file.o third_file.o -o my_program

main.o: main.cpp
    g++ $(CXXFLAGS) -c -o main.o main.cpp

other_file.o: other_file.cpp
    g++ $(CXXFLAGS) -c -o other_file.o other_file.cpp

third_file.o: third_file.cpp
    g++ $(CXXFLAGS) -c -o third_file.o third_file.cpp

还有其他类似的程序来处理。受欢迎的是 CMake 。

There are other similar programs to handle this. One that is popular is CMake.
