Using g++ and cmake to compile thread library error

Project scenario:

Use g++ to compile C++ code with thread library

g++ listing_1.1.cpp -o list_1.1

---

Problem Description

Error:

/usr/bin/ld: /tmp/ccYH9VAd.o: in function `std::thread::thread<void (&)(), , void>(void (&)())':
listing_1.1.cpp:(.text._ZNSt6threadC2IRFvvEJEvEEOT_DpOT0_[_ZNSt6threadC5IRFvvEJEvEEOT_DpOT0_]+0x33): undefined reference to `pthread_create'

---

Cause Analysis:

C++11 is not added, lpthread is not the default multithreading library under linux

---

solution:

The g++ command adds parameters:

g++ listing_1.1.cpp -std=c++11 -o list_1.1 -lpthread

compile successfully
