鏘掃描版本將不會在Xcode 4.2工作LLVM 3.0構建配置

Question

我安裝的Xcode 4.2最終版本能夠編譯爲iOS 5

我們正在使用詹金斯CI和運行鏘掃描 - 從llvm.org項目頁面構建。 （版本258）該項目配置爲使用LLVM 3.0（這是自Xcode 4.2以來的默認值）。現在，每當我嘗試運行掃描生成時我得到以下錯誤：

如果我使用靜態代碼的Xcode自我分析我獲得以下哪些沒有問題工作的輸出：

有有人知道我能做些什麼來讓scan-build再次運行而不禁用LLVM 3.0的使用？

Answer 1

它看起來像掃描構建決定使用llvm-gcc，這是混淆Xcode，因爲它期望運行鐺。可能只是掃描構建中的一個bug;我建議發送一封電子郵件給cfe-dev。

Answer 2

找到了解決具有檢驗器258的構建：

通行證此PARAM掃描建造：--use-CC =`其中clang`

然後使其通過構建詹金斯和掃描-build插件......這是一個有點麻煩：

移動掃描生成掃描-build.bin，然後進行掃描，生成是一個腳本：

#!/bin/sh 

dir=$(dirname $0) 
$dir/scan-build.bin --use-cc=`which clang` $@ 

的結果10是：/ usr/bin/clang

編輯：爲兩個項目工作，一個使用LLVM 3.0，另一個使用llvm-gcc4.2。

Answer 3

我提出了一個關於這個和其他問題（如掃描構建不識別ARC'd代碼）與蘋果的錯誤。

解決方法是安裝checker-260，請參閱http://clang-analyzer.llvm.org/release_notes.html以及對ccc-analyzer-http://llvm.org/viewvc/llvm-project?view=rev&revision=149094的此修改。希望將ccc-analyzer的修復程序整合到未來的scan-build版本中。

使用此最新版本的scan-build將避免您必須對上一個答案中描述的scan-build進行修改。
