Eclipse方法无法在一个简单的程序C ++中解决 [英] Eclipse Method could not be resolved in a simple program C++

问题描述

我有一个问题，Eclipse Indigo抱怨一个类的方法无法解决，但编译反正和工作正常（AFAIK）。这是一个非常简单的程序。这里是Population.cpp：

I have an issue with Eclipse Indigo complaining that methods of a class couldn't be resolved, but compiling anyway and working correctly (AFAIK). It's a very simple program. Here is Population.cpp:

#include <stdlib.h>
#include <iostream>
#include <time.h>
#include "Population.h"

Population::Population() {
    // TODO Auto-generated constructor stub

}

Population::~Population() {
    // TODO Auto-generated destructor stub
}

void Population::initializePop(int numBits, int N) {

    srand((unsigned)time(0));
    for(int i=0; i<N; i++) {
        x[i] = (char*) calloc(numBits, sizeof(char));
        for(int j=0; j<numBits; j++) {
            if( rand() < 0.5 )
                x[i][j] = 0;
            else
                x[i][j] = 1;
        }
    }

}

char** Population::getX() {
    return x;
}

void Population::printStuff() {
    std::cout << "Whatever";
}

现在，我构建该代码，一切都很好。在Eclipse中的另一个项目中，我将这样的代码调用：

Now, I build that code and everything is fine. In another project within Eclipse, I'm calling this code like this:

#include <typeinfo>
#include <string.h>
#include <iostream>
#include "cute.h"
#include "ide_listener.h"
#include "cute_runner.h"
#include "Population.cpp"

void testPopulationGeneration() {
    Population* p = new Population;
    int N = 10;
    int bits = 4;
    char** pop;

    ASSERTM("Population variable improperly initialized", dynamic_cast<Population*>(p));

    std::cout << p->printStuff();
    std::cout << "Ok...";
    p->initializePop(bits, N);

    pop = p->getX();
    ASSERTM("Pop not correct size.", sizeof(pop) == 10);
}

正如你所看到的，我也在C ++中运行TDD的CUTE插件。它不抱怨，当我声明p类型Population和第一个断言通过。我有点新C ++，但我确实要添加项目Population.cpp从测试项目的包含路径。

As you can see I'm also running the CUTE plugin for TDD in C++. It doesn't complain when I declare p as type Population and the first assertion passes. I'm somewhat new to C++, but I did make sure to add the project that Population.cpp is from to the include path for the test project.

这不是一个巨大的交易，因为它不影响任何明显的对我，但它仍然非常恼人。我没有看到它应该这样做的情况。

It's not a huge deal as it's not affecting anything obvious to me, but it's still very annoying. I don't see a situation where it should do this.

感谢任何帮助！
