How to build a openldap library for iphone on OSX? - iphone

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.

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.

Answer 1

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.

Answer 2

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

^
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.
