gcc does not fully support std::thread yet:
http://gcc.gnu.org/projects/cxx0x.html
http://gcc.gnu.org/onlinedocs/libstdc++/manual/status.html
Use boost::thread in the meantime.
Edit
Although the following compiled and ran fine for me with gcc 4.4.3:
#include <thread>
#include <iostream>
struct F
{
void operator() () const
{
std::cout<<"Printing from another thread"<<std::endl;
}
};
int main()
{
F f;
std::thread t(f);
t.join();
return 0;
}
Compiled with
g++ -Wall -g -std=c++0x -pthread main.cpp
Output of a.out
:
Printing from another thread
Can you provide the full code? Maybe there’s some obscure issue lurking in those ...
s?
