7085	Boost pool library it not header only as claimed in documentation	Roger Pawlowski <rppawlo@…>	Chris Newbold	"Hi,

I have been trying to use the bool pool library out of the current release 1.50.0.  The documentation page claims the library is header only, but it pulls in the threads library which is not header only.  You can reproduce this with the code:


#include <boost/pool/pool_alloc.hpp>

int main () {
  return 0;
}

I get the following error on gnu 4.3.5 compilers:

Linking CXX executable Panzer_roger_junk.exe
CMakeFiles/Panzer_roger_junk.dir/roger.cpp.o: In function `__static_initialization_and_destruction_0':
/home/rppawlo/install_boost_1_50_0/include/boost/system/error_code.hpp:214: undefined reference to `boost::system::generic_category()'
/home/rppawlo/install_boost_1_50_0/include/boost/system/error_code.hpp:215: undefined reference to `boost::system::generic_category()'
/home/rppawlo/install_boost_1_50_0/include/boost/system/error_code.hpp:216: undefined reference to `boost::system::system_category()'
collect2: ld returned 1 exit status

The issue is that <boost/pool/pool_alloc.hpp> includes <boost/pool/poolfwd.hpp> which includes <boost/pool/detail/mutex.hpp> which includes <boost/thread/mutex.hpp>  which includes <boost/thread/pthread/mutex.hpp> which includes <boost/thread/exceptions.hpp> 

The <boost/thread/exceptions.hpp> directly uses the boost system library which is not header only.
