当我在 xcode 4.2 上运行我的项目时，我得到了 31 个 .o 文件丢失错误的响应
31 错误看起来像这样

我也遇到了链接器错误，比如
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)
谁能帮我解决这个问题？
最佳答案
一个典型的 iPhone 项目针对三种不同的架构进行编译:armv6 和 armv7(两代不同的 iPhone 处理器)和 i386(针对模拟器)。在当前的构建运行中，您对 armv7 的构建最少。这是最重要的架构，因为 Apple 只接受至少具有此架构的构建(如果我没记错的话)。
不幸的是，您链接的库不包含此体系结构的代码。 (这就是为什么您会在顶部收到警告)。以下错误消息确认它确实是由 pjsip 和 pjmedia 库引起的。
我不知道您是在某处下载库还是从源代码构建它们。但是您需要至少为 armv7 构建的库。更好的办法是为所有架构构建库。
你最好关注这个 section 入门 页面的一部分，该页面展示了如何针对多种架构进行构建。
