Once built, lipo can be used to combine the ARM v6 and v7 variants into a
universal library.
An ARM v7s version of libjpeg-turbo, for iPhone 5 and iPad 4th Generation
devices, can be built by using the iPhone 5 SDK in XCode 4.5. You will have to
adjust IOS_PLATFORMDIR, IOS_SYSROOT, and IOS_GCC accordingly, and use the
following compiler flags:
IOS_CFLAGS="-march=armv7s -mcpu=swift -mtune=swift -mfpu=neon"
Unfortunately, XCode 4.5 also dropped support for ARM v6, so it will not be
possible to use a single version of XCode to build a universal binary that
supports both the iPhone 3G and earlier and the iPhone 5/iPad 4 and later.
Even more unfortunately, XCode 4.5 requires OS X 10.7, which means that we
cannot currently install and test it.
Once built, lipo can be used to combine the ARM v6, v7, and/or v7s variants
into a universal library.

On OS X systems, this creates a Macintosh package and disk image in which the
libjpeg-turbo static libraries contain ARM architectures necessary to build
iOS applications. If building on an x86-64 system, the binaries will also
contain the i386 architecture, as with 'make udmg' above. You should first
configure ARM v6 and ARM v7 out-of-tree builds of libjpeg-turbo (see
"Building libjpeg-turbo for iOS" above.) If you are building an x86-64
configure ARM v6, ARM v7, and/or ARM v7s out-of-tree builds of libjpeg-turbo
(see "Building libjpeg-turbo for iOS" above.) If you are building an x86-64
version of libjpeg-turbo, you should configure a 32-bit out-of-tree build as
well. Next, build libjpeg-turbo as you would normally, using an out-of-tree
build. When it is built, run 'make iosdmg' from the build directory. The
build system will look for the ARM v6 build under {source_directory}/iosarmv6
by default, the ARM v7 build under {source_directory}/iosarmv7 by default,
and (if applicable) the 32-bit build under {source_directory}/osxx86 by
default, but you can override this by setting the BUILDDIR32, BUILDDIRARMV6,
and/or BUILDDIRARMV7 variables on the make command line as shown above.
