Strange Errors while including boost

[Malang]

I'm using boost::threads for spawning multiple threads and in order to use functors for thread i'm using boost::bind but including <boost/bind.hpp> in my file util.hpp gives following errors:(I'm using FC 8 with g++ version 4.1.2).

I have realy tried hard but couldn't find whats the problem and how to resolve it, but to no avail. if i comment the <boost/bind.hpp> there are no errors and compiler complains that there is no bind in boost...

Thanks in Advance

Here is the code

	{// local block for the thread group
				boost::thread_group tgroup;
				for(UINT j=0; j < np+1;++j)
				{
					presult[j].clear();
					if(j==0)
					{
						tgroup.add_thread(new boost::thread(
														boost::bind(&Ft:::ScanFt,
																rfilter,hinfo,presult[j])));
					}
					else
					{
						tgroup.add_thread(new boost::thread(
														boost::bind(&Ft:::ScanFt,
																pfilter,hinfo2,presult[j])));

					}
				}
				tgroup.join_all();
			}// local block for the thread group

Are you using a different library that already defined _2 etc?

For example, boost::lambda also uses it.

What version of boost?

Is it blowing up on a syntax error?

Ft:::ScanFt

[Malang]

Boost version is { BOOST_LIB_VERSION "1_34_1" } and i'm just using boost::thread & boost::progress no other header file is being included


Is it blowing up on a syntax error?
Ft:::ScanFt no it was just a typo
