[Boost-users] building boost on MAC link error in .dylib

Subject: [Boost-users] building boost on MAC link error in .dylib

Hi,

I am trying to build boost 1.42.0 on MAC but I am having some problem. I am using the following command line
./bjam --build-dir=/tmp/build-boost toolset=gcc stage

At the end of build I get most of the ".a" version of lib but none of ".dylib"(dynamic library). I see multiple of the following error for different library, "...failed gcc.link.dll stage/lib/libboost_math_tr1.dylib...".

I usually work on window and new to MAC, so could some one point me what's I am doing wrong?

System Configuration:
MAC OS X, Version 10.6.4.
X Code version :3.2.3

Here is the partial build log, remove some of the lines to make sure more than one linking error is included.
