If you want to download the tar format, the zip press enter is incorrect. confg may be faulty. The following is a record of the library has build deployments for most platforms, but unfortunately not IOS. this document describes how to build libfreetype. A as a universal binary for iOS and the MAC (i386, x86_64, ARM7 ). Download the sourcedownload the latest FreeType sourcecode from
SourceForge. Open a terminal and extract the archive. Compiling the librarywe have to compile the library four times, once for each architecture. i386

$ ./configure CFLAGS="-arch i386"$ make

This forces configure to use the i386 architecture and build the library. the built library is located at objs /. libs/libfreetype. a. we copy this to our top level folder and build the next architecture.

$ cp objs/.libs/libfreetype.a libfreetype-i386.a

X86_64similar build setup for x86_64, notice the addition of make clean, we want to completely remove the i386 code.

$ ./configure CFLAGS="-arch x86_64";make clean;make$ cp objs/.libs/libfreetype.a libfreetype-x86_64.a

Arm77.is used on iPhone 3gs and newer. there are quite a few arguments that need to be passed to configure to make it build for arm7. I'm going under the assumption that you're targeting IOS 5.1 using gcc-4.2 as your compiler. if this is not what you want,
Please update the arguments below accordingly.

$ ./configure --prefix=/usr/local/iphone --host=arm-apple-darwin --enable-static=yes --enable-shared=no CC=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc  CFLAGS="-arch armv7 -pipe -mdynamic-no-pic -std=c99 -Wno-trigraphs -fpascal-strings -O2 -Wreturn-type -Wunused-variable -fmessage-length=0 -fvisibility=hidden -miphoneos-version-min=5.1 -I/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.1.sdk/usr/include/libxml2 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.1.sdk" CPP=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/llvm-cpp-4.2 AR=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/ar LDFLAGS="-arch armv7 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.1.sdk -miphoneos-version-min=5.1"$ make clean;make$ cp objs/.libs/libfreetype.a libfreetype-arm7.a

Bringing it all together as a universal librarywe now have 4 individual libraries. to combine them into a single universal library use the lipo tool.

$ lipo -create -output libfreetype.a libfreetype-i386.a libfreetype-x86_64.a libfreetype-arm7.a

And thats it. You can check which ubuntures are in a library with the-Info argument.

$ lipo -info libfreetype.a

Ubuntures In the FAT file: libfreetype. A are: armv7 i386 x86_64refer to
