在为设备编译时，Apple Mach-O连接器错误

我刚刚升级到xcode 4.0，我不能再部署到iPhone，我得到一个苹果Mach-O链接器错误，它仍然适用于模拟器。

一分钟前我也遇到了同样的问题。把我引到这里，但没什么用。但我找到了问题所在并解决了它。问题是在我的头文件中，我已经声明了一个名为trig_node[SIZE]的struct类的实例。

我的头…

struct TrigNode
{
    float msin;
    float mcos;
    float mtan;
}trig_node[SIZE];

在我的.cpp文件中，我有一个函数来访问这个实例并返回答案。

float cos_table_(float deg)
{
    uint n = ((SIZE/DEGRE)*deg);
    return trig_node[n % DEGRE].mcos;
}

这就是导致我的链接错误。 因此，为了解决这个问题，我将三角表类“trig_node[SIZE]”的实例放在了.cpp文件中，该文件清除了错误。所以现在新的修复看起来是这样的

我的头…

struct TrigNode
{
    float msin;
    float mcos;
    float mtan;
};

我的。cpp文件 trig_node(大小)

float cos_table_(float deg)
{
    uint n = ((SIZE/DEGRE)*deg);
    return trig_node[n % DEGRE].mcos;
}

其他回答

对我来说，在XCode 4.5.x的设备上运行时出现了架构故障。

XCode 4.5不再支持armv6，所以我的解决方案是:

我刚刚编辑了所有库中的所有目标(three20Core, three20Common等)和libThree20:在构建设置中，只选择了“架构”和“有效架构”中的armv7和armv7s

我遇到了同样的问题，问题是我不小心在实现文件中导入了.m文件而不是.h文件。

不确定是否相关，但看到你正在运行三个e20库，你可能想要查看他们网站上的这篇文章:http://three20.info/article/2011-03-10-Xcode4-Support

奇怪的错误。对我来说，我只是清理并重新启动Xcode，问题就消失了。

对我来说，这是不小心导入了一个实现。”M”文件，而不是相应的头文件“。h”文件。当我发现项目构建恢复正常时。
