I was looking at some open source project that I thought was interesting and wanted to compile the code for myself. Unfortunately my visual studio 2010 isn't c++11 compliant enough so I installed gcc/g++ 4.7.2 and that doesn't work either
Here is a snippet that shows my problem.
> g++ --version
g++ (GCC) 4.7.2

>g++ -std=c++11 main.cpp
main.cpp: In function 'int main()':
main.cpp:5:2: error: 'mutex' is not a member of 'std'
main.cpp:5:13: error: expected ';' before 'mutex_'

Hmm..Are you using on Linux?

no... visual studio doesn't work too well on linux.

I only have g++ 4.6.1, but looking at /usr/local/include/c++/4.6.1/mutex it seems that the mutex class is protected by some #defines.
I found a (german) article on the web which mentions that you must have installed the pthread library.
