为iOS编译arm64和x86_64的Libical
我花了一些时间来编译iOS的arm64和x86_64架构的LibiCal（设备和模拟器）。 认为这可能对其他人有用。 这是我遵循的编译LibiCal-1.0的步骤。 我从下面的链接采取代码
编译libical
并修改了一下，以适应Xcode 5.1
1）从下面的URL下载LibiCal
http://sourceforge.net/projects/freeassociation/
解压并进入libCal-1.0文件夹。 然后运行
./bootstrap
（需要从http://www.jattcode.com/installing-autoconf-automake-libtool-on-mac-osx-mountain-lion/下载make工具）
使用下面的脚本
#!/bin/sh # SEE: http://www.smallsharptools.com/downloads/libical/ PATH="`xcode-select -print-path`/usr/bin:/usr/bin:/bin" # set the prefix PREFIX=${HOME}/Library/libical OUTPUTDIR=../libical-build export ARCH=arm64 # Select the desired iPhone SDK export SDKVER="7.1" export DEVROOT=`xcode-select --print-path` export SDKROOT=$DEVROOT/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS${SDKVER}.sdk export IOSROOT=$DEVROOT/Platforms/iPhoneOS.platform # Includes # find $DEVROOT -type d -name include|grep -i iphone|grep -i arm-apple-darwin|grep -vi install-tools|grep -vi simulator # $SDKROOT/usr/include # $DEVROOT/Platforms/iPhoneOS.platform/Developer/usr/llvm-gcc-4.2/lib/gcc/arm-apple-darwin10/4.2.1/include if [ ! -d $DEVROOT ] then echo "Developer Root not found! - $DEVROOT" exit fi echo "DEVROOT = $DEVROOT" if [ ! -d $SDKROOT ] then echo "SDK Root not found! - $SDKROOT" exit fi echo "SDKROOT = $SDKROOT" if [ ! -d $IOSROOT ] then echo "iOS Root not found! - $IOSROOT" exit fi echo "IOSROOT = $IOSROOT" # finding ld # find $DEVROOT -type f -name ld|grep -i iphone # Set up relevant environment variables export CPPFLAGS="-arch $ARCH -I$SDKROOT/usr/include -I$IOSROOT/Developer/usr/llvm-gcc-4.2/lib/gcc/arm-apple-darwin10/4.2.1/include" export CFLAGS="$CPPFLAGS -pipe -no-cpp-precomp -isysroot $SDKROOT" export CXXFLAGS="$CFLAGS" export LDFLAGS="-L$SDKROOT/usr/lib/ -arch $ARCH" export CLANG=$DEVROOT/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang #export CC=$IOSROOT/Developer/usr/bin/arm-apple-darwin10-llvm-gcc-4.2 #export CXX=$IOSROOT/Developer/usr/bin/arm-apple-darwin10-llvm-g++-4.2 export CC=$CLANG export CXX=$CLANG export LD=$IOSROOT/Developer/usr/bin/ld export AR=$IOSROOT/Developer/usr/bin/ar export AS=$IOSROOT/Developer/usr/bin/as export LIBTOOL=$IOSROOT/usr/bin/libtool export STRIP=$IOSROOT/Developer/usr/bin/strip export RANLIB=$IOSROOT/Developer/usr/bin/ranlib HOST=arm-apple-darwin10 if [ ! -f $CC ] then echo "C Compiler not found! - $CC" exit fi if [ ! -f $CXX ] then echo "C++ Compiler not found! - $CXX" exit fi if [ ! -f $LD ] then echo "Linker not found! - $LD" exit fi if [ -d $OUTPUTDIR/$ARCH ] then rm -rf $OUTPUTDIR/$ARCH fi find . -name \*.a -exec rm {} \; make clean ./configure --prefix=$PREFIX --disable-dependency-tracking --host $HOST CXX=$CXX CC=$CC LD=$LD AR=$AR AS=$AS LIBTOOL=$LIBTOOL STRIP=$STRIP RANLIB=$RANLIB make -j4 # copy the files to the arch folder mkdir -p $OUTPUTDIR mkdir -p $OUTPUTDIR/$ARCH cp `find . -name \*.a` $OUTPUTDIR/$ARCH/ xcrun -sdk iphoneos lipo -info $OUTPUTDIR/$ARCH/*.a echo $ARCH DONE echo "See $OUTPUTDIR" 修改行：11“导出ARCH = arm64”得到所需的架构，即arm64，armv7，armv7s。
这应该在../libical-build文件夹中为所需的体系结构创buildbin。
为x86_64构build。
使用以下命令为x86_64运行获取构build。
tar -xovf libical-1.0.tar cd libical-1.0 ./bootstrap ./configure make
这应该在文件夹src / libical / .libs / libical.a中创buildlibical.a。
创build一个胖库
使用下面的命令来build立胖库。 （请使用适当的lipo命令）。
export DEVROT=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/lip $DEVROOT/usr/bin/lipo -arch arm64 $OUTPUTDIR/armv6/libical.a -arch i386 $OUTPUTDIR/i386/libical_Simulator.a -arch armv7 $OUTPUTDIR/x86_64/libical.a -arch armv7s $OUTPUTDIR/x86_64/libical.a -arch x86_64 $OUTPUTDIR/x86_64/libical.a -create -output $OUTPUTDIR/libical_fat_universal.a
请设置适当的OUTPUTDIR环境variables。
我希望以上会帮助一些想快速构buildiOS的Libical的人。
我find了解决这个问题的方法。 我做的主要事情是添加下面的开关
-mios-simulator-version-min=7.0
这是我目前的脚本版本：
#!/bin/sh set -o xtrace # SEE: http://www.smallsharptools.com/downloads/libical/ PATH="`xcode-select -print-path`/usr/bin:/usr/bin:/bin" if [ ! -n "$ARCH" ]; then export ARCH=armv7 fi # Select the desired iPhone SDK export SDKVER="7.1" export DEVROOT=`xcode-select --print-path` if [ "i386" = $ARCH ] || [ "x86_64" = $ARCH ]; then export SDKROOT=$DEVROOT/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator${SDKVER}.sdk export MIOS="-mios-simulator-version-min=7.0" else export SDKROOT=$DEVROOT/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS${SDKVER}.sdk export MIOS="" fi; export IOSROOT=$DEVROOT/Platforms/iPhoneOS.platform if [ ! -d $DEVROOT ] then echo "Developer Root not found! - $DEVROOT" exit 1 fi echo "DEVROOT = $DEVROOT" if [ ! -d $SDKROOT ] then echo "SDK Root not found! - $SDKROOT" exit 1 fi echo "SDKROOT = $SDKROOT" if [ ! -d $IOSROOT ] then echo "iOS Root not found! - $IOSROOT" exit 1 fi echo "IOSROOT = $IOSROOT" # Set up relevant environment variables export CPPFLAGS="-arch $ARCH -I$SDKROOT/usr/include $MIOS --debug" export CFLAGS="$CPPFLAGS -pipe -no-cpp-precomp -isysroot $SDKROOT " export CXXFLAGS="$CFLAGS" export LDFLAGS="-L$SDKROOT/usr/lib/ -arch $ARCH" export CLANG=$DEVROOT/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang export CC=$CLANG export CXX=$CLANG export LD=$IOSROOT/Developer/usr/bin/ld export AR=$IOSROOT/Developer/usr/bin/ar export AS=$IOSROOT/Developer/usr/bin/as export LIBTOOL=$IOSROOT/usr/bin/libtool export STRIP=$IOSROOT/Developer/usr/bin/strip export RANLIB=$IOSROOT/Developer/usr/bin/ranlib export LIPO="xcrun -sdk iphoneos lipo" export HOST=arm-apple-darwin10 if [ ! -f $CC ] then echo "C Compiler not found! - $CC" exit fi if [ ! -f $CXX ] then echo "C++ Compiler not found! - $CXX" exit fi if [ ! -f $LD ] then echo "Linker not found! - $LD" exit fi if [ -d $OUTPUT_DIR/$ARCH ] then rm -rf $OUTPUT_DIR/$ARCH fi find ./src -name \*.a -exec rm {} \; make clean ./configure --prefix="$OUTPUT_DIR" --disable-dependency-tracking --host $HOST CXX=$CXX CC=$CC LD=$LD AR=$AR AS=$AS LIBTOOL=$LIBTOOL STRIP=$STRIP RANLIB=$RANLIB make -j4 # copy the files to the arch folder mkdir -p $OUTPUT_DIR mkdir -p $OUTPUT_DIR/$ARCH cp `find . -name \*.a` $OUTPUT_DIR/$ARCH/ cp config.log $OUTPUT_DIR/$ARCH/config.log $LIPO -info $OUTPUT_DIR/$ARCH/*.a echo $ARCH DONE echo "See $OUTPUT_DIR"
我已经开始为这个库构build一个Objective C包装器，你可以在https://github.com/ahalls/XbICalendar看到进展情况。我可以使用一些build议甚至一些帮助的眼球。
那些想用iOS编译cmake（来自github）的最新版本的libical，请查看我的答案：
