Build OpenLDAP client for iOS - no SASL - ios

Question

Since Apple is systematically deprecating OpenLDAP for iOS and OS X (some features which are needed has been removed in 10.10), my team decided to get latest OpenLDAP, build it and include libraries to application.
I need only client functionality.
Build for MacOS is not a problem:
$ ./configure --with-tls=openssl --disable-slapd \
> --prefix="`pwd`/openldap-build/common" \
> --exec-prefix="`pwd`/openldap-build/MacOS"
$ make depend
$ make
$ make install
This goes smoothly.
Problem is building for iOS. I've found nice solution which allows to build such external libraries for iOS. I tweak this bash script to go with ~openLDAP` code:
#!/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
Configuration and make depend are Ok. make fails on each iOS target with this error:
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

^
1 error generated.
make[2]: *** [sasl.o] Error 1
make[1]: *** [all-common] Error 1
make: *** [all-common] Error 1
Form what I can see SALS is not available for iOS and this is source of problems.
How I can overcome this problem? Can I configure openLDAP differently so it will use something else? Or is there a decent way to provide SASL for iOS?

I'm not familiar with iOS/OSX, but to disable Cyrus SASL you could try
--without-cyrus-sasl
in addition to your other ./configure flags, i.e. you need to run
./configure --with-tls=openssl --disable-slapd \
--without-cyrus-sasl \
--prefix="`pwd`/openldap-build/common" \
--exec-prefix="`pwd`/openldap-build/MacOS"
For further flags info check out
./configure --help
and this nice reference.
