谷歌测试和XCode 4.6

XCode 4.6.3中的google测试存在问题

大家好,

我已经将google测试集成到我的XCode项目中，并使用基本的命令行工具 单元测试似乎工作正常（添加了guest.framework，正确设置了DYLD_LIBRRY_路径）

但是，只要我添加到对象fixture EXPECT_EQ（0，object.PublicMember）类型 测试时，我得到以下链接器错误

有什么建议我做错了什么吗

这是因为单元测试项目的构建选项与gtest项目不同。

---

确保构建选项如“Apple LLVM-Language”和“Apple LLVM-Language-C++”都是相同的。

我也遇到了同样的问题

---

在这两个项目中都选择libstdc++。

这里概述了另一个解决方案：它不使用框架，而是安装到/usr/local中，从而为情况带来了一些理智

请记住，必须重命名libs以“lib”开头，例如libgtest.a

还要记住，您必须同时链接到libgtest.a和libgtest_main.a。如果没有后者，您将收到关于缺少主要方法的投诉

---

关于C++方言和库的评论是适用的，但是我发现在生成框架并试图链接到它时很难控制这些。

< P>默认General.xcconfig指向10.4 SDK，将它改为10.10个固定问题，对于我< /P>可能的解决方案：
