I've been having some troubles figuring out why this error is occuring deep within the bowls of other code.

This occurs when I include thread & mutex header files from boost libraries for a class that has a single thread implemented.

Visual Studio 2008 level 4

c:\boost\include\boost-1_39\boost\date_time\microsec_time_clock.hpp(103) : warning C4244: 'argument' : conversion from 'int' to 'unsigned short', possible loss of data c:\boost\include\boost-1_39\boost\thread\thread_time.hpp(20) : see reference to class template instantiation 'boost::date_time::microsec_clock<time_type>' being compiled1>c:\boost\include\boost-1_39\boost\date_time\microsec_time_clock.hpp(103) : warning C4244: 'argument' : conversion from 'int' to 'unsigned short', possible loss of data

... and a few other errors.

There is absalutely no implicit coversions within the code I have written.

I simply create a single thread within the entire program.

If anyone knows or could point me in the right direction would be great!

Thanks

Not all boost compiles cleanly specially using warning level 4.
I use well placed pragma to turn them on and off.
#pragma warning(push)
#pragma warning (disable : 4100) // '' : unreferenced formal parameter
#include <boost/variant.hpp>
#pragma warning(pop)

If you tell the Boost mailing list about this including your compiler, someone may actually get around to fixing it.
