How to build a openldap library for iphone on OSX?

Question

I am trying to build openldap-2.4.23 library for iOS3 and 4 but when I try to run configure I get error :

>./configure --disable-slapd --disable-shared --enable-static --host=arm-apple-darwin

configure: WARNING: If you wanted to set the --build type, don't use --host.
If a cross compiler is detected then cross compile mode will be used.

configure: error: C compiler cannot create executables
See `config.log' for more details.

My env settings are like this :

export DEVROOT="/Developer/Platforms/iPhoneOS.platform/Developer"
export SDKROOT="/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.3.sdk"
export CC="${DEVROOT}/usr/bin/gcc"
export LD="${DEVROOT}/usr/bin/ld"
export AR="${DEVROOT}/usr/bin/ar"
export AS="${DEVROOT}/usr/bin/as"
export NM="${DEVROOT}/usr/bin/nm"
export CPPFLAGS="-I${SDKROOT}/usr/lib/gcc/arm-apple-darwin10/4.2.1/include -I${SDKROOT}/usr/include"
export CPP="${DEVROOT}/usr/bin/cpp ${CPPFLAGS}"
export CFLAGS="${CPPFLAGS} -arch armv6 -pipe -no-cpp-precomp"
export LDFLAGS="-L${SDKROOT}/usr/lib"

By the way, I succeeded to configure after the CFLAGS and LDFALGS are modified as follows :

export CFLAGS="${CPPFLAGS} -pipe -no-cpp-precomp"
export LDFLAGS=""

However, that results of make & make install are not armv architecture :

> lipo -detailed_info libldap.a
input file libldap.a is not a fat file
Non-fat file: libldap.a is architecture: i386

How can I build armv6 architecture openldap library? Anyone, please help!!

Thanks.

You are compiling it on Mac OS X Lion aren't you? – tamasgal May 10 '11 at 18:43 — tamasgal, May 10 '11 at 18:43

I think I'm one step closer to the solution (it configuration is successful). I've found similar problem here and simply adjusted build script so it would work on openLDAP.

#!/bin/bash

PLATFORMPATH="/Applications/Xcode.app/Contents/Developer/Platforms"
TOOLSPATH="/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin"
export IPHONEOS_DEPLOYMENT_TARGET="8.0"
pwd=`pwd`

findLatestSDKVersion()
{
    sdks=`ls $PLATFORMPATH/$1.platform/Developer/SDKs`
    arr=()
    for sdk in $sdks
    do
       arr[${#arr[@]}]=$sdk
    done

    # Last item will be the current SDK, since it is alpha ordered
    count=${#arr[@]}
    if [ $count -gt 0 ]; then
       sdk=${arr[$count-1]:${#1}}
       num=`expr ${#sdk}-4`
       SDKVERSION=${sdk:0:$num}
    else
       SDKVERSION="8.0"
    fi
}

buildit()
{
    target=$1
    hosttarget=$1
    platform=$2

    echo =============================================================
    echo = building for target $target platform $platform ... =
    echo =============================================================

    if [[ $hosttarget == "x86_64" ]]; then
        hostarget="i386"
    elif [[ $hosttarget == "arm64" ]]; then
        hosttarget="arm"
    fi

    export CC="$(xcrun -sdk iphoneos -find clang)"
    export CPP="$CC -E"
    export CFLAGS="-arch ${target} -isysroot $PLATFORMPATH/$platform.platform/Developer/SDKs/$platform$SDKVERSION.sdk -miphoneos-version-min=$SDKVERSION"
    export AR=$(xcrun -sdk iphoneos -find ar)
    export RANLIB=$(xcrun -sdk iphoneos -find ranlib)
    export CPPFLAGS="-arch ${target}  -isysroot $PLATFORMPATH/$platform.platform/Developer/SDKs/$platform$SDKVERSION.sdk -miphoneos-version-min=$SDKVERSION"
    export LDFLAGS="-arch ${target} -isysroot $PLATFORMPATH/$platform.platform/Developer/SDKs/$platform$SDKVERSION.sdk"

    mkdir -p $pwd/output/$target

     ./configure --disable-shared --host=$hosttarget-apple-darwin --with-tls=openssl --disable-slapd --prefix="$pwd/output-build/common"  --exec-prefix="$pwd/output-build/$target"

    make depend
    # make clean
    make
    make install

    echo =============================================================
    echo = Success for target $target platform $platform ... =
    echo =============================================================
}

findLatestSDKVersion iPhoneOS

buildit armv7 iPhoneOS
buildit armv7s iPhoneOS
buildit arm64 iPhoneOS
buildit i386 iPhoneSimulator
buildit x86_64 iPhoneSimulator

#LIPO=$(xcrun -sdk iphoneos -find lipo)
#$LIPO -create $pwd/output/armv7/lib/libpresage.a  $pwd/output/armv7s/lib/libpresage.a $pwd/output/arm64/lib/libpresage.a $pwd/output/x86_64/lib/libpresage.a $pwd/output/i386/lib/libpresage.a -output libpresage.a

Problem is that build error is reported (when executing make):

Making all in /Users/maru/Documents/openldap-2c705e4/libraries
  Entering subdirectory liblutil
cc -g -O2 -I../../include        -I../../include     -arch x86_64  -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator8.4.sdk -miphoneos-version-min=8.4  -c -o sasl.o sasl.c
sasl.c:26:10: fatal error: 'sasl/sasl.h' file not found
#include <sasl/sasl.h>
         ^
1 error generated.
make[2]: *** [sasl.o] Error 1
make[1]: *** [all-common] Error 1
make: *** [all-common] Error 1

If I understand documentation o SASL correctly it is not available for iOS. So it looks like I'm one step closer then @alkain, but still didn't find final solution.

This may be a little late for you, however I ported OpenLDAP to iOS using Xcode. The project can be cloned from github. https://github.com/bindle/iOSPorts

There is some documentation and examples in the project.
