Bus is only for 13.10. I'm learning c++ and I tried to write a simple code using std::thread (code is in attachment). I found info, that the code won't build without -pthread/-lpthread g++ option. I build code with every position of this flags and with std=c++11/std=c++0x, but I've got the same error: shkiper@server:~/C++$ g++ thread.cpp -pthread -std=c++11 -o thread shkiper@server:~/C++$ ./thread terminate called after throwing an instance of 'std::system_error' what(): Enable multithreading to use std::thread: Operation not permitted Аварийный останов (сделан дамп памяти) shkiper@server:~/C++$ I tryed to build this code on live cd - same error.

I tryed to build this code on live cd - same error.
It bullds and works on ubuntu <13.10.
I think, g++ doesn't links pthread lib:
