I know several people have successfully achieved this already but I'm not an expert in this area and would appreciate a little advice. My plan is to roughly follow the end-to-end build instructions for MaxOSX on the website, but to use a configure script for each package to set the various options needed to create the simulator and iOS versions of the library. Following a previous post and various search results, I'm using the following configure script for the simulator : #!/bin/sh export DEVROOT=/Developer/Platforms/iPhoneSimulator.platform/Developer export SDKROOT=$DEVROOT/SDKs/iPhoneSimulator4.2.sdk export CPPFLAGS="-I$SDKROOT/usr/lib/gcc/i686-apple-darwin10/4.2.1/include/ -I$SDKROOT/usr/include/ -I$SDKROOT/System/Library/Frameworks/" export CFLAGS="$CPPFLAGS -arch i686 -pipe -no-cpp-precomp -isysroot $SDKROOT" export CPP="$DEVROOT/usr/bin/cpp $CPPFLAGS" export CXXFLAGS="$CFLAGS" LIBNAME="cairosim" ../configure CXX=$DEVROOT/usr/bin/i686-apple-darwin10-g++-4.2.1 CC=$DEVROOT/usr/bin/i686-apple-darwin10-gcc-4.2.1 LD=$DEVROOT/usr/bin/ld --host=i686-apple-darwin However, I'm getting the following error : 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 checking for arm-apple-darwin-gcc... /Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/arm-apple-darwin10-gcc-4.2.1 checking whether the C compiler works... no Looking at the config.log file the error seems to be at this point : configure:3463: checking whether the C compiler works configure:3485: /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/i686-apple-darwin10-gcc-4.2.1 -I/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.2.sdk/usr/lib/gcc/i686-apple-darwin10/4.2.1/include/ -I/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.2.sdk/usr/include/ -I/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.2.sdk/System/Library/Frameworks/ -arch i686 -pipe -no-cpp-precomp -isysroot /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.2.sdk -I/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.2.sdk/usr/lib/gcc/i686-apple-darwin10/4.2.1/include/ -I/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.2.sd k/usr/include/ -I/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.2.sdk/System/Library/Frameworks/ conftest.c >&5 cc1: error: unrecognized command line option "-arch" configure:3489: $? = 1 configure:3527: result: no If anyone can shed some light on what I'm doing wrong, I'd be very grateful.
