I have installed gcc 4.1.2 (from Cent OS 5.5 repos), boost 1.44, and built all 
the libraries. I am able to link to all other libraries I try. As soon as I so 
much as add the include for boost::filesystem, and attempt to build my single 
.cpp file, I get the following errors:

 In function `__static_initialization_and_destruction_0(int, int)':
testbuild.cpp:(.text+0xfa): undefined reference to 
`boost::system::generic_category()'
testbuild.cpp:(.text+0x106): undefined reference to 
`boost::system::generic_category()'
testbuild.cpp:(.text+0x112): undefined reference to 
`boost::system::system_category()'
collect2: ld returned 1 exit status

The linking stage fails and despite hours of googling I see no clear solution. I 
would be grateful for any advice on how to move past this, as it's the only 
thing holding me back from developing with boost. To be clear again, simply 
including <boost/filesystem.hpp> is enough to cause this when performing a link 
against libboost_filesystem.a.
