使用cmake错误链接boost日志 [英] linking boost log using cmake error

问题描述

什么会导致以下问题: 我试图在cmake项目中使用boost :: log.

我的CMakeList.txt文件如下:

cmake_minimum_required(VERSION 3.10)
project(boostLogTest)
set(CMAKE_CXX_STANDARD 11)
add_executable(boostLogTest main.cpp)
ADD_DEFINITIONS(-DBOOST_LOG_DYN_LINK) #####  edit after DiCri's answer #####
find_package(Boost REQUIRED COMPONENTS log system)

if (Boost_FOUND)
    include_directories(${Boost_INCLUDE_DIRS})

    message("Boost VERSION: ${Boost_VERSION}")
    message("Boost INCLUDE_DIRS: ${Boost_INCLUDE_DIRS}")
    message("Boost Boost_LIBRARY_DIRS: ${Boost_LIBRARY_DIRS}")
    message("Boost LIBRARIES: ${Boost_LIBRARIES}")

    TARGET_LINK_LIBRARIES(boostLogTest ${Boost_LIBRARIES})
endif ()

我的main.cpp文件看起来像这样:

#include <iostream>

#include <boost/log/trivial.hpp>

int main(int, char*[])
{
    BOOST_LOG_TRIVIAL(trace) << "A trace severity message";
    BOOST_LOG_TRIVIAL(debug) << "A debug severity message";
    BOOST_LOG_TRIVIAL(info) << "An informational severity message";
    BOOST_LOG_TRIVIAL(warning) << "A warning severity message";
    BOOST_LOG_TRIVIAL(error) << "An error severity message";
    BOOST_LOG_TRIVIAL(fatal) << "A fatal severity message";

    return 0;
}

我的CMake输出如下

-Boost版本:1.64.0

-找到了以下Boost库:

-日志

-系统

-date_time

-log_setup

-文件系统

-线程

-正则表达式

-计时

-原子Boost版本:106400 Boost INCLUDE_DIRS:/usr/local/include Boost Boost_LIBRARY_DIRS:/usr/local/lib Boost

图书馆: /usr/local/lib/libboost_log.so;/usr/local/lib/libboost_system.so;/usr/local/lib/libboost_date_time.so;/usr/local/lib/libboost_log_setup.so;/usr/local/lib/libboost_log.set.so;/usr/local/lib/libboost_filesystem.so;/usr/local/lib/libboost_thread.so;/usr/local/lib/libboost_regex.so;/usr/local/lib/libboost_chrono.so;/usr/local/lib/libboost_atomic.so

-配置完成

-生成完成

-构建文件已写入:/home/.../CLionProjects/boostLogTest/cmake-build-debug

但是在链接时出现以下错误消息:

[50％]链接CXX可执行文件boostLogTest

CMakeFiles/boostLogTest.dir/main.cpp.o:在函数"main"中:

/home/.../CLionProjects/boostLogTest/main.cpp:7:对`boost :: log :: v2s_mt_posix :: trivial :: logger :: get()'的未定义引用

在DiCri的答案后进行 现在，我收到以下错误消息:

[50％]链接CXX可执行文件boostLogTest

/usr/bin/ld:CMakeFiles/boostLogTest.dir/main.cpp.o:对符号'pthread_rwlock_unlock @@ GLIBC_2.2.5'的未定义引用

make [1]:*** [CMakeFiles/boostLogTest.dir/rule]错误2

Makefile:118:目标"boostLogTest"的配方失败

make:*** [boostLogTest]错误2

如果我添加

set(Boost_USE_STATIC_LIBS        ON) 

库的路径更改为* .a文件，例如:

Boost LIBRARIES: /usr/local/lib/libboost_log.a;/usr/local/lib/libboost_system.a;...

所有列出的库(* .so和* .a)都存在于此文件夹中.

我想念什么?

解决方案

只需尝试添加此行

#define BOOST_LOG_DYN_LINK 1

作为main.cpp文件的第一行，我认为它应该可以工作，有人遇到了相同的问题

and my main.cpp file looks like this:

#include <iostream>

#include <boost/log/trivial.hpp>

int main(int, char*[])
{
    BOOST_LOG_TRIVIAL(trace) << "A trace severity message";
    BOOST_LOG_TRIVIAL(debug) << "A debug severity message";
    BOOST_LOG_TRIVIAL(info) << "An informational severity message";
    BOOST_LOG_TRIVIAL(warning) << "A warning severity message";
    BOOST_LOG_TRIVIAL(error) << "An error severity message";
    BOOST_LOG_TRIVIAL(fatal) << "A fatal severity message";

    return 0;
}

My CMake output is the following

-- Boost version: 1.64.0

-- Found the following Boost libraries:

-- log

-- system

-- date_time

-- log_setup

but while linking I get the following error messages:

[ 50%] Linking CXX executable boostLogTest

Edit after DiCri's answer: Now I get the following error messages:

[ 50%] Linking CXX executable boostLogTest

/usr/bin/ld: CMakeFiles/boostLogTest.dir/main.cpp.o: undefined reference to symbol 'pthread_rwlock_unlock@@GLIBC_2.2.5'

If I add

set(Boost_USE_STATIC_LIBS        ON) 

the paths to the libraries change to a *.a file, like:

Boost LIBRARIES: /usr/local/lib/libboost_log.a;/usr/local/lib/libboost_system.a;...

All listed libraries (the *.so and the *.a) exist in this folders.

What am I missing?

解决方案

Just try to add this line

#define BOOST_LOG_DYN_LINK 1

As the first line of the main.cpp file, i think it should work, someone got your same issue here

If that doesn't work, try to add this line

ADD_DEFINITIONS(-DBOOST_LOG_DYN_LINK)

To CMake file You need to add OpenMP package too
