架构 i386 的未定义符号将项目升级到 iOS 5

问题描述

我一直在搜索 SO 和 Google，但还没有发现任何有用的东西.

I've been scouring SO and Google but haven't found anything helpful yet.

我们正在更新现有的 iOS 项目以针对 iOS 5 构建.

We're updating our existing iOS project to build against iOS 5.

我们的项目有两个目标，第一个是我们的静态库，第二个是单元测试应用程序 (GHUnit).

Our project has two targets, the first is our static library and the second is a Unit Test application (GHUnit).

在构建单元测试目标时，它成功编译了静态库，但随后无法链接它并显示以下输出:

When building the unit test target it successfully compiles the static library, but then fails to link against it with the following output:

我已经尝试搜索未找到的符号，但谷歌确实有 0 个结果.

I've tried searching for the unfound symbols but google literally has 0 results.

我假设静态库是用单元测试目标不是的东西构建的，但我找不到它.

I assume the static library is being built with something that the unit test target isn't but I cannot find it.

有人有什么建议吗?

干杯

推荐答案

这对我很有效(用粗体捕捉设置):

This worked for me well (catch the settings with bold):
