运行otest会在映像中找到旧的ABI元数据

Question

我试图从终端运行单元测试，但每次都失败。以下消息是当我尝试在终端中运行otest时得到的消息。

objc[42339]: GC: forcing GC OFF because OBJC_DISABLE_GC is set
objc[42339]: found old-ABI metadata in image /Developer/Tools/otest !
Segmentation fault

我需要Hudson集成的单元测试输出，并将iOS部署目标设置为4.2。这就是我要运行的代码。

export SDKROOT=/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.2.sdk
export BUILD_DIR=~/Documents/XCode/MyApp/build
export BUILD_PRODUCTS_DIR=~/Documents/XCode/MyApp/build/Debug-iphonesimulator

export DYLD_ROOT_PATH=$SDKROOT
export DYLD_FRAMEWORK_PATH=$BUILD_PRODUCTS_DIR:$SDKROOT
export IPHONE_SIMULATOR_ROOT=$SDKROOT
export CFFIXED_USER_HOME="~/Library/Application Support/iPhone Simulator/User/"
export OBJC_DISABLE_GC=YES
export DYLD_LIBRARY_PATH=$BUILD_PRODUCTS_DIR:$SDKROOT
export DYLD_NEW_LOCAL_SHARED_REGIONS=YES
export DYLD_NO_FIX_PREBINDING=YES

arch -i386 /Developer/Tools/otest MyApp.octest

Answer 1

bbum是正确的，我使用的是错误的 otest。Described here我需要运行以下命令

$ find /Developer -name otest
/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.2.sdk/Developer/usr/bin/otest
/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.0.sdk/Developer/usr/bin/otest
/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.1.sdk/Developer/usr/bin/otest
/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.2.sdk/Developer/usr/bin/otest
/Developer/Tools/otest

显然，通过输出，我为我的应用程序选择了正确的otest，并且它工作得很好。
