如何为 iOS 构建 GLib

Question

我想在我的 iOS 应用程序中使用 lasem，但是编译 lasem 需要 glib。如何构建它？

我从https://git.gnome.org/browse/glib/refs/tags 下载 glib-2.37.4。然后我使用 autogen.sh 获取配置文件，运行 make 并安装在 mac 上。我写了一个shell脚本尝试为iOS构建glib，作为打击：

export path=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/llvm-gcc-4.2/bin/:$path
 export CC=arm-apple-darwin10-llvm-gcc-4.2
 export CFLAGS="-arch armv7"
 export LDFLAGS="-miphoneos-version-min=2.0"
 export LD="/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/ld--disable-cxx"
./configure --prefix=/usr/local/ios/ --host=arm-apple-darwin10 --enable-static=yes --enable-shared=no CC=$CC CFLAGS=$CFLAGS CPP=cpp AR=ar LDFLAGS=$LDFLAGS LD=$LD

当我运行这个脚本时，返回：

checking for arm-apple-darwin10-gcc... arm-apple-darwin10-llvm-gcc-4.2
checking whether the C compiler works... no
configure: error: in `/Users/tinyfool/Downloads/glib-2.34.3':
configure: error: C compiler cannot create executables

我能做什么？

鉴于您已经为 iOS 构建了 libffi 和 proxy-libintl，并将它们安装到与此脚本使用相同的 PREFIX，这将为您构建 GLib：

#! /bin/bash

export MINVER="5.1" # the minimum supported OS version
export SDKVER="5.1" # SDK version
export PREFIX="$HOME/built-for-ios" # where the library goes

export DEVROOT="/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer"
export SDKROOT="${DEVROOT}/SDKs/iPhoneOS${SDKVER}.sdk"
export PKG_CONFIG_LIBDIR="${PREFIX}/lib/pkgconfig:${SDKROOT}/usr/lib/pkgconfig"
export COMMON_FLAGS="-arch armv7 -isysroot ${SDKROOT}"
export CPPFLAGS="-I${PREFIX}/include ${COMMON_FLAGS} -miphoneos-version-min=${MINVER}"
export CFLAGS="${CPPFLAGS}"
export LDFLAGS="-L${PREFIX}/lib ${COMMON_FLAGS} -Wl,-iphoneos_version_min,${MINVER}"
export CC="${DEVROOT}/usr/bin/gcc"
export CXX="${DEVROOT}/usr/bin/g++"
export OBJC="${CC}"
export LD="${CC}"

[ ! -d "${PREFIX}" ] && mkdir -p "${PREFIX}"
./configure --prefix="${PREFIX}" \
--build="x86_64-apple-darwin" \
--host="arm-apple-darwin" \
--enable-static \
--disable-shared \
