CMakeLists.txt 中配置Boost庫

未配置正確時報錯：

‘__static_initialization_and_destruction_0(int, int)’中：
/usr/include/boost/system/error_code.hpp:221：對‘boost::system::generic_category()’未定義的引用
/usr/include/boost/system/error_code.hpp:222：對‘boost::system::generic_category()’未定義的引用
/usr/include/boost/system/error_code.hpp:223：對‘boost::system::system_category()’未定義的引用

CMakeLists.txt中，增加以下配置：

add_definitions(-DBOOST_ERROR_CODE_HEADOR_ONLY)# for boost

find_package(Boost REQUIRED COMPONENTS system thread)#for boost

include_directories(${Boost_INCLUDE_DIRS})


# 可執行文件編譯時的配置
add_executable(_node_name_
src/_file_name_.cpp)
target_link_libraries(_node_name_ 
   ${PROJECT_NAME}
   ${Boost_LIBRARIES}

   )

 

示例：

src/main.cpp

#include <iostream>
#include <boost/thread/thread.hpp> 
#include <boost/thread/mutex.hpp> 
 
boost::mutex mutex;
 
void print_block(int n, char c)
{

    mutex.lock();
    for (int i = 0; i < n; ++i)
    {
        std::cout << c;
    }
    std::cout << '\n';
    mutex.unlock();
}
 
int main(int argc, char* argv[])
{
    boost::thread thread1(&print_block, 300, '*');
    boost::thread thread2(&print_block, 300, '$');
 
    thread1.join();
    thread2.join();
 
    return 0;
}

CMakeLists.txt配置：

# cmake needs this line
cmake_minimum_required(VERSION 2.8)
 
# Define project name
project(mutex_project)
 
SET(CMAKE_CXX_FLAGS ${CMAKE_CXX_FLAGS} "-std=c++11")
 
## System dependencies are found with CMake's conventions
find_package(Boost REQUIRED COMPONENTS
    thread
)
 
if(NOT Boost_FOUND)
    message("NOT found Boost")
endif()
 
include_directories(${Boost_INCLUDE_DIRS})
# Declare the executable target built from your sources
add_executable(${PROJECT_NAME} src/main.cpp)
target_link_libraries(${PROJECT_NAME} ${Boost_LIBRARIES})
