| Can't use std::thread with CDT and MinGW [message #778436] |

I am wanting to use std::thread with my Eclipse Indigo and MinGW (gcc 4.6.2)
combination on Windows 7 but it reports that thread is not a member of std.
I have included <thread> but what else do I need to do to have std::thread
as a
usable class?

Thanks but it's a pity that your link points back to another of my own posts
on the subject.
Someone else has pointed out how to define the symbol in my original
question but the class std::thread is still not visible because of other
symbols not being defined. I have posted about this 3 times now and the
first two times I requested help in having that original symbol defined. In
my most recent post I did not refer to that symbol anymore because I now
know how to define it; the problem is simply that I still cannot use
std::thread.
So, does anyone know how I can use std::thread? The other symbols which are
not defined probably mean that other dependencies are not met in this
configuration so I really need to hear from someone who has either managed
to use this class or can explain why I cannot use it.

Thanks Rob but I must be missing something as it still doesn't work.
I have added that flag to Discovery Options->Compiler invocation arguments
and also to Settings->GCC C++ Compiler->Miscellaneous->Other flags as well
as rebuilding the index and rebuilding the project but any reference to
std::thread is still in red and I get this compiler error:
'thread' is not a member of 'std'
Are you sure you are able to actually use std::thread with this flag and/or
is there something else that I am supposed to be doing?
