Hi all,

Up until now I have been developing exclusively with VC++ 2010, and there my 
project builds just fine and without warnings. However, I am also planning 
to target Unix so I figured that a first step would be to make sure my 
project builds with MinGw. I set up my path environment variable to include 
the location of the MinGw 4.7.0 bin directory, and I built Boost with the 
following parameters:

b2 variant=release link=static runtime-link=static threading=multi 
toolset=gcc

Everything seems to be working fine (stage/lib contains all the .a files 
that I would expect). However, when I attempt to build my program I get tons 
of errors like the following:

myprog_main.o:myprog_main.cpp:(.text+0x28ef): undefined reference to

Etc...

I tried to specify -DBOOST_NO_LIB and add all the libraries manually, but no 
luck. Then I thought that maybe there's a problem with the fact that there 
are spaces in some of my directory names, so I copied the relevant .a files 
to the same directory as the program itself but still with no success. At 
this point, I'm swamped. I have managed to compile MinGw programs in the 
past that used Boost Thread, so I have no idea why it is not working with 
this version of Boost. Any suggestions would be highly appreciated.

Kind regards,
