未定义的引用的boost::log_mt_posix:basic_attribute_set ::~ basic_attribute_set()”

Newbie question... I'm trying out Boost for the first time because I want to test drive the Boost Log library. I built this test program...

新手问题…我第一次尝试Boost，因为我想测试Boost日志库。我建立了这个测试程序…

#include <boost/log/trivial.hpp>
#include <iostream>

int fibonacci(int num) {
    int i;
    int a = 1;
    int b = 1;

    for (i = 2; i <= num; ++i) {
        BOOST_LOG_TRIVIAL(info) << "Iteration " << i << " (a = " << a << ", b = " << b << ")...";
        b = a + b;
        a = b - a;
    }

    return a;
}

int main() {
    std::cout << "8th fibonacci number: " << fibonacci(8) << std::endl;
    return 0;
}

About Boost Log syntax

关于提高日志语法

Did I install Boost Log incorrectly? Am I missing crucial libraries? Did I omit necessary linker flags?

我是否错误地安装了Boost日志?我错过了重要的图书馆吗?我省略了必要的链接标记吗?

3 个解决方案

#1

It looks like you haven't built log?

看起来你还没建日志?

Once you've copied the log header files, etc into the corresponding folders in your boost distro (keep the same structure i.e. merge the headers to the headers, the libs folder into the libs folder of your boost distro, etc), you still need to build boost and then like John mentioned, link against it. That's why the link you referred to above points you to the standard boost build instructions.

一旦你复制日志头文件等等到相应的文件夹在你提升发行版(保持相同的结构即合并头的头,填词文件夹到库文件夹增加发行版的,等等),你仍然需要建立促进然后像约翰·提到,链接。这就是为什么你提到的链接指向了标准的boost构建指令。

It's a while ago, but AFAIR on linux you simply run ./bjam in the root of your boost folder.

这已经是很久以前的事了，但是在linux上你只是运行。/bjam在你的boost文件夹的根目录。

#2

You need to add something like -lboost-log-mt to your link line.

您需要在链接行中添加类似-lboost-log-mt的内容。

#3

Maybe switch unright version of the boost_log.

可能切换到boost_log的不正确版本。

I have the same issue for undefined reference to "boost::log::v2_mt_posix::core::push_record_move(boost::log::v2_mt_posix::record&)"

对于未定义的引用，我有相同的问题，“boost::log::v2_mt_posix:: push_record_move(boost::log::v2_mt_posix:: recordand)”

I build the libboost_log by myself. And I use the nm to grep the push_record_move found that, "boost::log::v2s_mt_posix::core::push_record_move(boost::log::v2s_mt_posix::record&)"

我自己构建libboost_log。我使用nm来grep, push_record_move发现，“boost::log::v2s_mt_posix:: push_record_move(boost::log::v2s_mt_posix:: recordand)”

From the experience of before, should add some cflag in the Makefile.

从以前的经验来看，应该在Makefile中添加一些cflag。
