所以我在使用 scan-build 构建 xcode 项目时遇到链接器错误
对于我正常的 xcodebuild 命令，我使用以下命令
xcodebuild -target LibCoreMobileGHUnit -configuration Debug -sdk iphonesimulator5.0 clean build
它对链接器阶段使用以下选项
"/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ld"
-demangle
-dynamic
-arch i386
-all_load
-ios_simulator_version_min 5.0.0
-syslibroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator5.0.sdk

-F/Users/ops/workspace/MobileFramework_Test_IOS_Client/LibCoreMobile/LibCoreMobileGHUnit
-F/Users/ops/workspace/MobileFramework_Test_IOS_Client/LibCoreMobile/ExternalFrameworks
这是成功的
但是当我运行以下
scan-build -k -v -v -o ../clangScanBuildReports xcodebuild -target LibCoreMobileGHUnit -configuration Debug -sdk iphonesimulator5.0 clean build
它与以下选项链接：
"/usr/llvm-gcc-4.2/libexec/gcc/i686-apple-darwin11/4.2.1/ld"
-dynamic
-arch i386
-all_load
-ios_simulator_version_min 5.0.0

所以这里有一些东西在运行 scan-build 时有所不同，它似乎使用了不同的链接器 /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ld vs /usr/llvm- gcc-4.2/libexec/gcc/i686-apple-darwin11/4.2.1/ld
在普通的 xcodebuild 中它有一个额外的选项 -demangle 并且在 scan-build 中它缺少两个 libclang 库
-lc++ /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../lib/clang/4.1/lib/darwin/libclang_rt.profile_ios.a
-lSystem /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../lib/clang/4.1/lib/darwin/libclang_rt.ios.a
有谁知道我如何强制将库包含在“扫描构建”执行的链接器标志中。
