问题描述
我在 Windows 7 操作系统上使用 DEV GNU c++ 编译器.我需要知道如何编译具有多个源文件的程序.这是示例，
I am using DEV GNU c++ compiler on windows 7 OS. I need to know how a program with more than one source file can be compiled. here is example,
#FILE1
void f1()
{
printf("this is another file under same program");
}
#FILE2
int main()
{
f1();
return 0;
}
实际上我需要这个来测试静态、extern 类说明符如何处理多个文件.所以只有我现在必须学习如何在 C 中的单个程序中处理多个文件..
Actually I need this to test how static, extern class specifier works with more than one file. So only I have to learn now how works with more than one files in a single program in C..
提前致谢
推荐答案
多个文件"的技术术语将是 翻译单位:
The technical term for 'multiple files' would be translation units:
g++ file1.cpp file2.cpp -o program
或者你把编译和链接分开
Or you separate compilation and linking
g++ -c file1.cpp -o file1.o
g++ -c file2.cpp -o file2.o
# linking
g++ file1.o file2.o -o program
但这通常没有意义，除非您有一个更大的项目(例如使用 make)并希望减少构建时间.
But that usually doesn't make sense unless you have a larger project (e.g. with make) and want to reduce build times.
