Using libcurl on iOS 5 as an alternative to NSURLConnection

Question

Update: NSURLConnection now seems to properly support 100-Continue. In any case, this answer contains a link to the script to build libcurl for iOS/OSX.

Important Update for people getting: C compiler cannot create executables
Make sure you install the command line XCode tools...

From XCode menu select: Preferences --> downloads --> Command Line Tools

...and hit "Install" if not installed.

The issue with the above script is that it works with older versions of XCode. If you installed the latest XCode, the location of all the compiler tools will be different. I've changed the script to support both old and new XCode versions, and have some error checking built-in. Does this help?

Below -- I assume SDK version 5.1 -- you may need to modify that...

#!/bin/bash

set -e

export SDK=5.1

checkExists() {

    if [ ! -e $1 ]
    then
        echo "Didn't find: $1 -- try to locate parts of this to see how to fix the path"
        exit 1
    else 
        echo "using $1"
    fi

}

buildit() {

    target=$1
    platform=$2

    root="/Applications/Xcode.app/Contents/Developer/Platforms/${platform}.platform/Developer"
    oldRoot="/Developer/Platforms/${platform}.platform/Developer"

    if [ ! -d "${root}" ]
    then
        root="${oldRoot}"
    fi

    if [ ! -d "${root}" ]
    then
        echo " "
        echo "Oopsie.  You don't have an iOS SDK root in either of these locations: "
        echo "   ${root} "
        echo "   ${oldRoot}"
        echo " "
        echo "If you have 'locate' enabled, you might find where you have it installed with:"
        echo "   locate iPhoneOS.platform | grep -v 'iPhoneOS.platform/'"
        echo " "
        echo "and alter the 'root' variable in the script -- or install XCode if you can't find it... "
        echo " "
        exit 1
    fi

    export CC="${root}/usr/bin/gcc"
    export CFLAGS="-arch ${target} -isysroot ${root}/SDKs/${platform}${SDK}.sdk"
    export CPP="${root}/usr/bin/llvm-cpp-4.2"
    export AR="${root}/usr/bin/ar"
    export RANLIB="${root}/usr/bin/ranlib"

    checkExists ${CC}
    checkExists ${root}/SDKs/${platform}${SDK}.sdk
    checkExists ${CPP}
    checkExists ${AR}
    checkExists ${RANLIB}

    ./configure --disable-shared --without-ssl --without-libssh2 --without-ca-bundle --without-ldap --disable-ldap --host=${target}-apple-darwin10

    make clean
    make
    $AR rv libcurl.${target}.a lib/*.o
}

buildit armv6 iPhoneOS
buildit armv7 iPhoneOS
buildit i386 iPhoneSimulator

lipo -create libcurl.armv7.a libcurl.armv6.a libcurl.i386.a -output libcurl.a
