How to build GLib for iOS

Question

I want to use lasem in my iOS App, but compiling lasem needs glib. How to build it?

I download glib-2.37.4 from https://git.gnome.org/browse/glib/refs/tags. I then used autogen.sh to get a configure file, ran make and installed on mac. I wrote a shell script try to build glib for iOS, as blow:

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

When I run this script, return as:

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

What can I do?

Given that you have built libffi and proxy-libintl for iOS, and installed both those to the same PREFIX as this script uses, this will build GLib for you:

#! /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 \
