我一直在搜索SO和Google，但还没有发现任何有用的信息。
我们正在更新现有的iOS项目，以针对iOS 5进行构建。
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)。
在构建单元测试目标时，它可以成功编译静态库，但是无法通过以下输出链接到该静态库:

ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)
我曾尝试搜索未找到的符号，但google字面上有0个结果。
我假设静态库是用某种不是单元测试目标的东西构建的，但是我找不到它。
有没有人有什么建议？
干杯
最佳答案
这对我来说很好(用粗体捕获设置):
