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。

这对我来说很有用:

去

1)产品>清洁

2) Windows >项目

3)选择你的项目，点击“删除”衍生数据

4)产品>构建

其他回答

我遇到了同样的问题:只是不小心删除了一个.m文件，而项目中有.h文件。当我恢复.m文件时，问题消失了。

我也遇到过同样的问题，但我解决了。在我的案例中，“架构”设置导致了这个问题。在我的项目文件中，Build Settings选项卡，Architectures被设置为armv6。我把它改为标准(armv7)，做清洁和构建。然后它成功了!

在我的案例中，问题是在不同的目标下指定不同的体系结构。我用armv6, armv7和cocos2d标准(amrv7)构建我的应用程序目标。进入构建设置，确保您的架构与所有目标一致。

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;
}

我对同样问题的解决方案:在“项目”中添加“其他链接器标志”，而不是在“目标”中。我把它移到了目标，它不应该在项目里。
