我需要从mainCalib.cpp文件
创建头文件mainCalib.hmainCalib.cpp文件包含opencv的校准样本..
所以最后我可以从main.cpp文件执行该程序：

答案 0 :(得分：1)
首先阅读include guards。
然后将实际的类定义放在头文件中。
然后将类函数 implementation 放在源文件中。
标头文件
#ifndef HEADER_FILE_H
#define HEADER_FILE_H
class MyClass
{
public:
MyClass(int val);
~MyClass();
void some_function();
private:
int value;
};
#endif // HEADER_FILE_H
源文件
#include <iostream>
#include "header_file.h"
MyClass::MyClass(int val)
: value(val)
{
}
MyClass::~MyClass()
{
}
void MyClass::some_function()
{
std::cout << "value is " << value << '\n';
}
主要源文件
#include "header_file.h"
int main()
{
MyClass my_object(5);
my_object.some_function();
}
另请注意，如果您希望从源文件外部调用它们，则不能在文件范围中使用static函数。使函数static限制与其定义的翻译单元的链接。
