用xcode4.2编译pjsip的麻烦

Question

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

和31错误看起来像这个

另外，我还得到了链接器错误，如

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

有人能帮我解决这个问题吗？

Answer 1

一个典型的iPhone项目为三种不同的体系结构编译：armv6和armv7 ( iPhone处理器的两代不同代)和i386 (用于模拟器)。在当前的构建运行中，您是armv7的最小构建。这是最重要的架构，因为苹果只接受至少这个架构的构建(如果我没有弄错的话)。

不幸的是，您正在链接的库不包含此体系结构的代码。(这就是为什么你会在顶部收到警告)。下面的错误消息确认它确实是由pjsip和pjmedia库引起的。

我不知道你是从某个地方下载了库，还是从源代码中构建的。但是，您将需要至少为armv7构建的库。更好的做法是为所有架构构建库。

最好遵循入门页面的这个部分，该页面展示了如何为多个体系结构构建。
