I got this figured out. For some reason gmail decided now to show me all the replies to my original thread. This is what I ended up using. boost::thread thrd(&DataParse::rets_init,dparse,instUUID); On Wed, Mar 18, 2009 at 1:38 PM, r ottmanj <rottmanj@hsmove.com> wrote:

Even after updating to boost 1.38 I still get this error. This is the current error that I get. Any help with this is greatly appreciated.

I am working on an application that takes use of boost::thread. During the initial method of my application I need to pass one argument to the method. As per the api documentation for boost::thread I am using the following:

boost::thread dataThread(dparse.dataMain,instUUID); dataThread.join();

However, when I attempt to use this, I get the following exception from my compiler. Is there something that I am missing? I do not see how my thread constructor is any different from the constructor in the api documentation.

Any help with this is greatly appreciated.

error: no matching function for call to ‘boost::thread::thread(<unresolved overloaded function type>, std::string&)’ /usr/include/boost/thread/thread.hpp:38: note: candidates are: boost::thread::thread(const boost::function0<void, std::allocator<boost::function_base> >&) /usr/include/boost/thread/thread.hpp:37: note: boost::thread::thread() /usr/include/boost/thread/thread.hpp:35: note: boost::thread::thread(const boost::thread&)

It looks like you have an older version of Boost that doesn't support extra arguments to the constructor. You'll need to use Boost.Bind.
