Hadoop - ld：找不到架构x86_64的符号

Question

我在运行hadoop管道代码时遇到问题。

我的环境是：Hadoop2.7.3 Mac10.13.3单节点。

我的代码如下：

#include <algorithm>
#include <limits>
#include <stdint.h>
#include <string>

#include "Pipes.hh"
#include "TemplateFactory.hh"
#include "StringUtils.hh"
using namespace std;

class MaxTemperatureMapper : public HadoopPipes::Mapper {
public:
  MaxTemperatureMapper(HadoopPipes::TaskContext& context) {
  }
  void map(HadoopPipes::MapContext& context) {
    std::string line = context.getInputValue();
    std::string year = line.substr(15, 4);
    std::string airTemperature = line.substr(87, 5);
    std::string q = line.substr(92, 1);
    if (airTemperature != "+9999" &&
        (q == "0" || q == "1" || q == "4" || q == "5" || q == "9")) {
      context.emit(year, airTemperature);
    }
  }
};

class MapTemperatureReducer : public HadoopPipes::Reducer {
public:
  MapTemperatureReducer(HadoopPipes::TaskContext& context) {
  }
  void reduce(HadoopPipes::ReduceContext& context) {
    int maxValue = INT_MIN;
    while (context.nextValue()) {
      maxValue = std::max(maxValue, HadoopUtils::toInt(context.getInputValue()));
    }
    context.emit(context.getInputKey(), HadoopUtils::toString(maxValue));
  }
};

int main(int argc, char *argv[]) {
  return runTask(HadoopPipes::TemplateFactory<MaxTemperatureMapper, MapTemperatureReducer>());
}

Makefile是：

HADOOP_INSTALL = /用户/的MacBookPro /文档/ Hadoop的2.7.5

CC = g ++

CCFLAGS = -I $（HADOOP_INSTALL）/ include

wordcount：wordcount-simple.cpp

$（CC）$（CCFLAGS）$＆lt; -Wall -L $（HADOOP_INSTALL）/ lib / native -lhadooppipes -lhadooputils -lpthread -lcrypto -lssl -g -O2 -o $ @

当我运行wordcount程序时，我遇到以下错误： - *

Undefined symbols for architecture x86_64:
  "HadoopPipes::runTask(HadoopPipes::Factory const&)", referenced from:
      _main in wordcount-simple-52c3c0.o

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [wordcount] Error 1

你能帮我解决这个问题吗？
