What is it that doesn't work? Compiler error? Link error? Runtime error?

Hi all,
I would like to know, if it is possible, to create an osg::Thread from
a c++ class-member-function. My guess is, that the osg::Thread is not
designed for that purpose, it relies on pthreads, doesn't it?
I created a simple program which uses threads in C:
//-------------<begin TestFader.c>------------------
#include <iostream.h>
#include <OpenSG/OSGGLUTWindow.h>
osg::Thread* tfadeOut;
void fadeOut(void *ptr){
cout << "it works!\n";
}
int startThread(){
// declaration & start of the thread
tfadeOut = dynamic_cast<osg::Thread
*>(osg::ThreadManager::the()->getThread("fOut"));
tfadeOut->runFunction(fadeOut, 0, NULL);
return 0;
}
int main(int argc, char **argv){
osg::osgInit(argc,argv);
startThread();
osg::Thread::join(tfadeOut);
return 0;
}
//-------------<end TestFader.c>------------------
This code works perfectly and prints out "it works". Nevertheless my
attempts to put the same code into a class won't bring any positive
results. My C++ code looks like this:
//-------------<begin TestFader.cpp>------------------
#include <iostream.h>
#include <OpenSG/OSGGLUTWindow.h>
class TestFader{
public:
osg::Thread* tfadeOut;
void fadeOut(void *ptr){
cout << "it works!\n";
}
int startThread(){
// declaration & start of the thread
tfadeOut = dynamic_cast<osg::Thread
*>(osg::ThreadManager::the()->getThread("fOut"));
tfadeOut->runFunction(TestFader::fadeOut, 0, NULL);
cout << "it works!\n";
return 0;
}
};
int main(int argc, char **argv){
TestFader *f = new TestFader();
osg::osgInit(argc,argv);
f->startThread();
osg::Thread::join(f->tfadeOut);
return 0;
}
//-------------<end TestFader.cpp>------------------
So has anybody got a hint for me on how to create threads from c++
class-member-functions with OSG-Threads? That would really be
appreciated.
Thanks, Markus
