Hi all,

I’ve updated xCode to version 5.1 and I’ve tried to compile curl with the latest iOS SDK released by Apple 7.1, but the compilation phase failed. I’ve attached below an example.
export IPHONEOS_DEPLOYMENT_TARGET="4.3"

export CC="/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang"
export CFLAGS="-arch armv7 -pipe -Os -gdwarf-2 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Deveoper/SDKs/iPhoneOS7.1.sdk"
export LDFLAGS="-arch armv7 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.1.sdk"

./configure --host=armv7-apple-darwin --with-zlib --disable-shared --enable-static --disable-ipv6 --disable-manual --disable-verbose

make -j `sysctl -n hw.logicalcpu_max`
I noticed this issue when configure is invoked:

Has someone experience on this issue?
