架构的未定义符号i386将项目升级到iOS 5 [英] Undefined symbols for architecture i386 Upgrading project to iOS 5

问题描述

我一直在搜索SO和谷歌，但还没有找到任何有用的东西。

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进行构建。

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).

构建单元测试目标时，它成功编译静态库，但是无法使用以下输出链接它：

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

我试过搜索不合格的符号但google字面意思得到0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但我找不到的东西构建的。

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

有没有人有任何建议？

干杯

推荐答案

这对我很有用（用粗体捕捉设置）：

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