thanks,

Ok, looking at the resulting libs, I realized that the gcc version in my
~/user-config.jam file was wrong, here's the new one:

#################################################################
# Compiler configuration
using darwin : 4.2.1~iphone
   :
/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc-4.2 -arch arm
   : <striper>
   : <architecture>arm <target-os>iphone <macosx-version>iphone-3.0
   ;
using darwin : 4.2.1~iphonesim
   :
/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/gcc-4.2
-arch i386
   : <striper>
   : <architecture>x86 <target-os>iphone <macosx-version>iphonesim-3.0
   ;
#################################################################

Ok, I wanted to play it dumb, but here is a shortcut. An estimate is that
each option in the following incantation took me 30 minutes of search on the
net.

So here is the command line I used to build boost for the iphone device (as
opposed to the simulator)

./bjam toolset=darwin architecture=arm target-os=iphone
macosx-version=iphone-3.0 link=static threading=single define=_LITTLE_ENDIAN
include=/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.0.sdk/usr/include/c++/4.2.1/armv6-apple-darwin9

Compilation succeded, so that's all good. I still three questions thought:

1) couldn't I make the command line shorter? maybe by migrating some of the
stuff in the last command line to the user-config.jam?
If so, an example would be great (for the include option for instance)

2) I'm now worrying a bit about the name of the generated lib:
libboost_filesystem-xgcc42-1_39.a
Is that what I should expect?
On boost 1.38.0, it was libboost_filesystem.a

3) Btw, how do I know which compiler (exact path) I'm using for sure because
all I can see is "darwin.compile.c++"?

Thanks,
