Hello,

I've recently added the Boost header libraries to my iPhone project,
but I'd also like to use some of the compiled libraries. I've looked
at the documentation and archives for the correct procedure, but I'm
hitting a snag.
I have added the following to the user-config.jam file:

using darwin : 4.0.1~iphone
   :
/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/g++
-arch arm
   : <striper>
   : <architecture>arm <target-os>iphone <macosx-version>iphone-2.0
   ;
using darwin : 4.0.1~iphonesim
   :
/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/g++
   : <striper>
   : <architecture>x86 <target-os>iphone <macosx-version>iphonesim-2.0
   ;

I then run bjam with the following parameters:

bjam toolset=darwin architecture=arm target-os=iphone
macosx-version=iphone-2.0 define=_LITTLE_ENDIAN

Which fails on linking with the following message:

darwin.link.dll

Any insights on what I'm doing wrong here?
