在 xcode4.2 上编译 pjsip 的问题

Question

当我在 xcode 4.2 上运行我的项目时，我得到了这样的响应，其中 .o 文件丢失了 31 个错误

那个 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？

Answer 1

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（用于模拟器）。在当前的构建运行中，您最少构建 armv7。这是最重要的架构，因为 Apple 只接受至少具有这种架构的构建（如果我没记错的话）。

很遗憾，您要链接的库不包含此架构的代码。 （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了这些库还是从源代码构建了它们。但是您需要至少为armv7 构建的库。更好的是为所有架构构建库。

您最好关注入门页面的section，该页面展示了如何为多种架构构建。
