Quantlib with boost for iOS build on xcode 4.6 - ios

Question

I'm trying to build quantlib for xcode 4.6.
The project of concern is this one: https://github.com/philipbarnes/quantlib-on-iOS
This quantlib project relies on this boost project: https://gitorious.org/boostoniphone/boostoniphone
My problem is I cannot get this boost to build, but I can get another version to build on github also by Pete.
One of the steps in building quantlib for iOS asks to set the boost dir. I tried to adjust this to no avail. 
This means I have a dir 'boostoniphone-huuskpes-boostoniphone' - which does not build and was said to be the version to use with the quantlib on iPhone project,
and the dir 'boostoniphone-master' which did build - it has a different build structure with folders and maybe setting the $BOOSTDIR variable in the quantlib project isn't so simple.
These outputs from the console have been shorted for more comfortable reading
My gitorious boost output says:
3 warnings generated.

as the other boost project works for me it, I try to link it into the buildql.sh script as a boost ref, but I get:

checking whether the C compiler works... no

and

A pointer to how to make frameworks may also be a solution? But I think getting the quantlib for iOS project to work is the real solution.
Coming back to the BOOST variable, in the buildql.sh file, changes such as the following have been made:
#: ${BOOST_HOME:=$HOME/workspace/huuskpes-boostoniphone}
: ${BOOST_HOME:=$HOME/workspace/boostoniphone-master/}
: ${BOOST_SRC:=$BOOST_HOME/src/boost_1_51_0}
The following were also altered to attempt to fit the 'boostoniphone-master'
: ${SRCDIR:=`pwd`/src}
: ${BUILDDIR:=`pwd`/build}
: ${PREFIXDIR:=`pwd`/prefix}
: ${FRAMEWORKDIR:=`pwd`/framework}
Thanks for any hints, potential solutions.

Changes to the buildql.sh script look like this:
: ${BOOST_HOME:=/Volumes/Untitled\ 1/workspace/boostoniphone-master/iphone-build/stage/lib}
: ${BOOST_SRC_HOME:=/Volumes/Untitled\ 1/workspace/boostoniphone-master/boostoniphone-master}
: ${BOOST_SRC:=$BOOST_SRC_HOME/src/boost_1_51_0/boost}
...
: ${SRCDIR:=/Volumes/Untitled\ 1/workspace/quantlib-on-iOS-master/QuantLib-1.2.1/src}
: ${BUILDDIR:=/Volumes/Untitled\ 1/workspace/quantlib-on-iOS-master/QuantLib-1.2.1/build}
: ${PREFIXDIR:=/Volumes/Untitled\ 1/workspace/quantlib-on-iOS-master/QuantLib-1.2.1/prefix}
: ${PREFIXDIR_2:=/Volumes/Untitled\ 1/workspace/quantlib-on-iOS-master/QuantLib-1.2.1/prefix}
: ${FRAMEWORKDIR:=/Volumes/Untitled\ 1/workspace/quantlib-on-iOS-master/./ql/.libs/libQuantLib.a}
Build command runs with a new error:
./buildql.sh -with-boost-include=/opt/local/include/ --with-boost-lib=/Volumes/Untitled 1/workspace/boostoniphone-master/iphone-build/stage --prefix=/opt/local/
Current output looks like this:

Answer 2

Rather than go into all the script details the following is the solution:
Set the paths carefully, that means, try not to have spaces or have data on external drive (although you can)
Set the parameters for the ARM chip, simulator and the iOS version installed very very carefully!
All in all that should be the most of it.
