测试代码是官方给的样例，

// main.cpp

#include "log4cpp/Category.hh"
#include "log4cpp/Appender.hh"
#include "log4cpp/FileAppender.hh"
#include "log4cpp/OstreamAppender.hh"
#include "log4cpp/Layout.hh"
#include "log4cpp/BasicLayout.hh"
#include "log4cpp/Priority.hh"

int main(int argc, char** argv) {
    log4cpp::Appender *appender1 = new log4cpp::OstreamAppender("console", &std::cout);
    appender1->setLayout(new log4cpp::BasicLayout());

    log4cpp::Appender *appender2 = new log4cpp::FileAppender("default", "program.log");
    appender2->setLayout(new log4cpp::BasicLayout());

    log4cpp::Category& root = log4cpp::Category::getRoot();
    root.setPriority(log4cpp::Priority::WARN);
    root.addAppender(appender1);

    log4cpp::Category& sub1 = log4cpp::Category::getInstance(std::string("sub1"));
    sub1.addAppender(appender2);

    // use of functions for logging messages
    root.error("root error");
    root.info("root info");
    sub1.error("sub1 error");
    sub1.warn("sub1 warn");

    // printf-style for logging variables
    root.warn("%d + %d == %s ?", 1, 1, "two");

    // use of streams for logging messages
    root << log4cpp::Priority::ERROR << "Streamed root error";
    root << log4cpp::Priority::INFO << "Streamed root info";
    sub1 << log4cpp::Priority::ERROR << "Streamed sub1 error";
    sub1 << log4cpp::Priority::WARN << "Streamed sub1 warn";

    // or this way:
    root.errorStream() << "Another streamed error";

    return 0;
}

错误如下：

/tmp/ccoWxTVC.o：在函数‘__static_initialization_and_destruction_0(int, int)’中：
/usr/local/include/log4cpp/Appender.hh:164：对‘log4cpp::Appender::AppenderMapStorageInitializer::AppenderMapStorageInitializer()’未定义的引用
/usr/local/include/log4cpp/Appender.hh:164：对‘log4cpp::Appender::AppenderMapStorageInitializer::~AppenderMapStorageInitializer()’未定义的引用
collect2: 错误：ld 返回 1

我认为最主要的是__static_initialization_and_destruction_0这个函数，但是我不知道是怎么回事？
Appender.hh的 164 行是

static Appender::AppenderMapStorageInitializer appenderMapStorageInitializer; // static initializer for every translation unit

系统是CentOS8，先记录一下。
