You need to correctly specify the member function pointer, and pass in
the 'this' pointer. Try boost::bind(&MyClass::ChildThreadFunc, this,
ii)

Hi,
I've had a good search on the mailing list and while some posts have got close to my problem and given me a few glues, my code does't quite work the way I want it to.
My goal is to have a (non-static) class member function run in a child thread + passing a parameter to it. The code I've got at the moment goes something like this:
void MyClass::spawn_threads() { for ( int ii = 0; ii < num_threads; ++ii) { threadGroup.create_thread( boost::bind( ChildThreadFunc, _1, ii)); } }
void MyClass::ChildThreadFunc( int &threadNumber) { // Does some work }
I get the following error on the create_thread line:
error: no matching function call to bind(<unknown type>, boost::arg<1>&, int&) cadiates are: .... boost:bind(F, A1, A2)[ with F= void (MyClass::*)(int&), A1=boost:arg<1>, A2=int]
I'm confused by the <unknown type> business. How do I tell it the correct type?
Maybe someone could point out where I've erred.
Cheers,
Steve.
