我一直在搜索 SO 和 Google，但還沒有發(fā)現(xiàn)任何有用的東西.
I've been scouring SO and Google but haven't found anything helpful yet.
我們正在更新現(xiàn)有的 iOS 項目以針對 iOS 5 構(gòu)建.
We're updating our existing iOS project to build against iOS 5.
我們的項目有兩個目標，第一個是我們的靜態(tài)庫，第二個是單元測試應(yīng)用程序 (GHUnit).
Our project has two targets, the first is our static library and the second is a Unit Test application (GHUnit).
在構(gòu)建單元測試目標時，它成功編譯了靜態(tài)庫，但隨后無法鏈接它并顯示以下輸出:
When building the unit test target it successfully compiles the static library, but then fails to link against it with the following output:

ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)
我已經(jīng)嘗試搜索未找到的符號，但谷歌確實有 0 個結(jié)果.
I've tried searching for the unfound symbols but google literally has 0 results.
我假設(shè)靜態(tài)庫是用單元測試目標不是的東西構(gòu)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.
有人有什么建議嗎?
干杯
推薦答案
這對我很有效(用粗體捕捉設(shè)置):
This worked for me well (catch the settings with bold):
