我有一个静态库目标，它有一个运行脚本构建阶段，可以为模拟器和设备创建一个 FAT 库到同一个 .a 文件中。

当我从Xcode (4.6.2)运行它时，构建中有一个点，其中状态是带有进度条的“正在运行的脚本”，但是在指定的目录中没有 .a 文件。

当我使用 Xcode 的构建从 CLI 运行时，有。有任何想法吗？

这是我的构建脚本，它是一个稍微修改过的标准脚本：

DEBUG_THIS_SCRIPT="false"
    if [ $DEBUG_THIS_SCRIPT = "true" ]
    then
    echo "########### TESTS #############"
    echo "Use the following variables when debugging this script; note that they may change on recursions"
    echo "BUILD_DIR = $BUILD_DIR"
    echo "BUILD_ROOT = $BUILD_ROOT"
    echo "CONFIGURATION_BUILD_DIR = $CONFIGURATION_BUILD_DIR"
    echo "BUILT_PRODUCTS_DIR = $BUILT_PRODUCTS_DIR"
    echo "CONFIGURATION_TEMP_DIR = $CONFIGURATION_TEMP_DIR"
    echo "TARGET_BUILD_DIR = $TARGET_BUILD_DIR"
    fi
    #####################[ part 1 ]##################
    # First, work out the BASESDK version number (NB: Apple ought to report this, but they hide it)
#    (incidental: searching for substrings in sh is a nightmare! Sob)
SDK_VERSION=$(echo ${SDK_NAME} | grep -o '.\{3\}$')
# Next, work out if we're in SIM or DEVICE
if [ ${PLATFORM_NAME} = "iphonesimulator" ]
then
OTHER_SDK_TO_BUILD=iphoneos${SDK_VERSION}
else
OTHER_SDK_TO_BUILD=iphonesimulator${SDK_VERSION}
fi
echo "XCode has selected SDK: ${PLATFORM_NAME} with version: ${SDK_VERSION} (although back-targetting: ${IPHONEOS_DEPLOYMENT_TARGET})"
echo "...therefore, OTHER_SDK_TO_BUILD = ${OTHER_SDK_TO_BUILD}"

# IF this is the original invocation, invoke WHATEVER other builds are required
#
# Xcode is already building ONE target...
#
# ...but this is a LIBRARY, so Apple is wrong to set it to build just one.
# ...we need to build ALL targets
# ...we MUST NOT re-build the target that is ALREADY being built: Xcode WILL CRASH YOUR COMPUTER if you try this (infinite recursion!)
#
#
# So: build ONLY the missing platforms/configurations.
if [ "true" == ${ALREADYINVOKED:-false} ]
then
echo "RECURSION: I am NOT the root invocation, so I'm NOT going to recurse"
else
# CRITICAL:
# Prevent infinite recursion (Xcode sucks)
export ALREADYINVOKED="true"
echo "RECURSION: I am the root ... recursing all missing build targets NOW..."
echo "RECURSION: ...about to invoke: xcodebuild -configuration \"${CONFIGURATION}\" -target \"${TARGET_NAME}\" -sdk \"${OTHER_SDK_TO_BUILD}\" ${ACTION} RUN_CLANG_STATIC_ANALYZER=NO"

ACTION="build"
#Merge all platform binaries as a fat binary for each configurations.
# Calculate where the (multiple) built files are coming from:
CURRENTCONFIG_DEVICE_DIR=${SYMROOT}/${CONFIGURATION}-iphoneos
CURRENTCONFIG_SIMULATOR_DIR=${SYMROOT}/${CONFIGURATION}-iphonesimulator
echo "Taking device build from: ${CURRENTCONFIG_DEVICE_DIR}"
echo "Taking simulator build from: ${CURRENTCONFIG_SIMULATOR_DIR}"
CREATING_UNIVERSAL_DIR=${SYMROOT}/${CONFIGURATION}-universal
echo "...I will output a universal build to: ${CREATING_UNIVERSAL_DIR}"
# ... remove the products of previous runs of this script
#      NB: this directory is ONLY created by this script - it should be safe to delete!
rm -rf "${CREATING_UNIVERSAL_DIR}"
mkdir "${CREATING_UNIVERSAL_DIR}"
#
echo "lipo: for current configuration (${CONFIGURATION}) creating output file: ${CREATING_UNIVERSAL_DIR}/${EXECUTABLE_NAME}"
lipo -create -output "${CREATING_UNIVERSAL_DIR}/${EXECUTABLE_NAME}" "${CURRENTCONFIG_DEVICE_DIR}/${EXECUTABLE_NAME}" "${CURRENTCONFIG_SIMULATOR_DIR}/${EXECUTABLE_NAME}"
fi

谢谢。
