pjsip在xcode4.2上编译的问题

Question

当我在 xcode 4.2 上运行我的项目时，我得到了这种响应，其中有 31 个 .o 文件丢失的错误

，并且 31 个错误看起来像这样

另外我还遇到了链接器错误，

ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

有人可以帮我解决这个问题吗？

Answer 1

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，您正在为 armv7 进行最少的构建。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架构的代码。 （这就是为什么你会在顶部收到警告）。以下错误消息确认它确实是由 pjsip 和 pjmedia 库引起的。

我不知道你是在某个地方下载了这些库还是从源代码构建了它们。但您需要至少为 armv7 构建的库。更好的是为所有架构构建库。

您最好按照入门<的部分进行操作< /em> 页面显示如何构建多个架构。
