我已经安装了Xcode 4.2最终版本，以便能够为iOS 5编译。
我们正在使用Jenkins进行CI并从llvm.org项目页面运行Clang scan-build。 （版本258）项目配置为使用LLVM 3.0（自Xcode 4.2以来是默认的）。现在每次我尝试运行scan-build时都会出现以下错误：

如果我使用Xcode self的静态代码分析，我会得到以下输出，但没有问题：

有人知道如何在不禁用LLVM 3.0的情况下再次运行扫描构建吗？
答案 0 :(得分：5)
找到了一个有checker-258构建的解决方案：
将此参数传递给scan-build： - use-cc =`which clang`
然后让它由jenkins和scan-build插件构建......这有点棘手：
将scan-build移至scan-build.bin，然后将scan-build设为脚本：
#!/bin/sh
dir=$(dirname $0)
$dir/scan-build.bin --use-cc=`which clang` $@
which clang的结果是：/ usr / bin / clang
编辑：适用于两个项目，一个使用LLVM 3.0，另一个使用llvm-gcc4.2。

我向Apple提出了一个关于此问题和其他问题的错误（例如扫描构建不识别ARC'd代码）。
修复方法是安装checker-260，请参阅http://clang-analyzer.llvm.org/release_notes.html以及对ccc-analyzer - http://llvm.org/viewvc/llvm-project?view=rev&revision=149094的此修改。希望ccc-analyzer的修复程序将被整合到未来的scan-build版本中。
使用此最新版本的scan-build将避免您必须对上一个答案中描述的scan-build进行修改。
答案 2 :(得分：0)
看起来scan-build决定使用llvm-gcc，这让Xcode感到困惑，因为它期待运行clang。可能只是扫描构建中的一个错误;我建议发送电子邮件给cfe-dev。
