CMake解決c++11的phread庫問題：undefined reference to `pthread_create’

方法一

PROJECT(HELLO)
set(CMAKE_CXX_FLAGS "${CAMKE_CXX_FLAGS} -std=c++11")
AUX_SOURCE_DIRECTORY(. SRC_LIST)
ADD_EXECUTABLE(hello ${SRC_LIST})

從cmake的CMakeLists.txt文件中可以看出cmake是像g++使用c++11特性一樣，都有-std=c++11，所以像一樣加個-pthread解決就行。

PROJECT(HELLO)
set(CMAKE_CXX_FLAGS "${CAMKE_CXX_FLAGS} -std=c++11 -pthread")
AUX_SOURCE_DIRECTORY(. SRC_LIST)
ADD_EXECUTABLE(hello ${SRC_LIST})

方法二

使用包Threads和鏈接${CMAKE_THREAD_LIBS_INIT}

PROJECT(HELLO)
set(CMAKE_CXX_FLAGS "${CAMKE_CXX_FLAGS} -std=c++11")
FIND_PACKAGE(Threads)
AUX_SOURCE_DIRECTORY(. SRC_LIST)
ADD_EXECUTABLE(hello ${SRC_LIST})
TARGET_LINK_LIBRARIES(hello ${CMAKE_THREAD_LIBS_INIT})
