Subject: [Boost-users] undefined reference to `boost::thread_resource_error::thread_resource_error()'

On ubuntu, I have a piece of software linking against the boost thread
library. Linking with boost version 1.40 I don't have any problem,
whereas switching to 1.41 I got the

undefined reference to

In the sources I see that this constructor is now inlined and if I do

nm -C -D | grep thread_resource_error

from this (1.40)

0000ee80 T boost::thread_resource_error::thread_resource_error(int)
0000ee00 T boost::thread_resource_error::thread_resource_error()
0000ee40 T boost::thread_resource_error::thread_resource_error(int)
0000edc0 T boost::thread_resource_error::thread_resource_error()
0000f4c0 T boost::thread_resource_error::~thread_resource_error()
0000f500 T boost::thread_resource_error::~thread_resource_error()
0000f530 T boost::thread_resource_error::~thread_resource_error()
0000eec0 T boost::thread_resource_error::what() const
00013e00 V typeinfo for boost::thread_resource_error
0000ffc0 V typeinfo name for boost::thread_resource_error
00013d98 V vtable for boost::thread_resource_error

I got this (1.41)

0000b6e0 W boost::thread_resource_error::~thread_resource_error()
0000b720 W boost::thread_resource_error::~thread_resource_error()
0000b480 W boost::thread_resource_error::what() const
0001282c V typeinfo for boost::thread_resource_error
0000ed00 V typeinfo name for boost::thread_resource_error
00012848 V vtable for boost::thread_resource_error

The symbol is weak now. I should be not a problem, right? But I got the
unresolved ref

What is the best option to have my stuff compiled without the unresolved
