cocoa touch - Gnu Scientific Library in iOS

Question

How can I use the GNU Scientific Library in an iOS application?

I tried following this tutorial: http://www.os-scientific.org/devel/gslxcode/index.html. But it seems not to work for iOS this way, only for OS X. After I added the GSL source code to XCode using an "external build system", XCode wants to build the target of that GSL subproject for the OS X SDK instead of the iOS SDK.

Ok! The configuration that worked for me:

sudo ./configure --disable-shared --disable-dependency-tracking --host=armv7-apple-darwin10 CFLAGS="-I/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.3.sdk/usr/include -I/Library/iPhone/include -isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.3.sdk" CC="/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/arm-apple-darwin10-gcc-4.2.1" CPP=cpp LDFLAGS="-isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.3.sdk"
